TIP! Sort multiple columns simultaneously by holding down the Shift key and clicking a second, third or even fourth column header!

Getting started

To use the tablesorter plugin, include the jQuery library and the tablesorter plugin inside the <head> tag of your HTML document:

<!-- choose a theme file -->
<link rel="stylesheet" href="/path/to/theme.default.css">
<!-- load jQuery and tablesorter scripts -->
<script type="text/javascript" src="/path/to/jquery-latest.js"></script>
<script type="text/javascript" src="/path/to/jquery.tablesorter.js"></script>

<!-- tablesorter widgets (optional) -->
<script type="text/javascript" src="/path/to/jquery.tablesorter.widgets.js"></script>

tablesorter works on standard HTML tables. You must include THEAD and TBODY tags:

<table id="myTable" class="tablesorter">
  <thead>
    <tr>
      <th>Last Name</th>
      <th>First Name</th>
      <th>Email</th>
      <th>Due</th>
      <th>Web Site</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>Smith</td>
      <td>John</td>
      <td>jsmith@gmail.com</td>
      <td>$50.00</td>
      <td>http://www.jsmith.com</td>
    </tr>
    <tr>
      <td>Bach</td>
      <td>Frank</td>
      <td>fbach@yahoo.com</td>
      <td>$50.00</td>
      <td>http://www.frank.com</td>
    </tr>
    <tr>
      <td>Doe</td>
      <td>Jason</td>
      <td>jdoe@hotmail.com</td>
      <td>$100.00</td>
      <td>http://www.jdoe.com</td>
    </tr>
    <tr>
      <td>Conway</td>
      <td>Tim</td>
      <td>tconway@earthlink.net</td>
      <td>$50.00</td>
      <td>http://www.timconway.com</td>
    </tr>
  </tbody>
</table>

Start by telling tablesorter to sort your table when the document is loaded:

$(function(){
  $("#myTable").tablesorter();
});

Click on the headers and you'll see that your table is now sortable! You can also pass in configuration options when you initialize the table. This tells tablesorter to sort on the first and second column in ascending order.

$(function(){
  $("#myTable").tablesorter({ sortList: [[0,0], [1,0]] });
});

NOTE! tablesorter will auto-detect most data types including numbers, dates, ip-adresses for more information see Examples

Examples

These examples will show what's possible with tablesorter. You need Javascript enabled to run these samples, just like you and your users will need Javascript enabled to use tablesorter.

Configuration

tablesorter has many options you can pass in at initialization to achieve different effects
TIP! Click on the link in the property column to reveal full details (or toggle|show|hide all) or double click to update the browser location.
Property Type Default Description Link
Property Type Default Description Link
cancelSelection Boolean true Indicates if tablesorter should disable selection of text in the table header (TH). Makes header behave more like a button.
String "" Additional CSS class applied to style the header with a ascending sort (v2.11).

Changed to empty string ("") in v2.11, as the "tablesorter-headerAsc" class will always be added to a header cell with an ascending sort; this option now contains any additional class names to add.

Example from the blue theme:

.tablesorter-blue .tablesorter-headerAsc {
  background-color: #9fbfdf;
  background-image: url(black-asc.gif);
}
Default changed v2.5 to "tablesorter-headerAsc". Default changed v2.1.7 to "tablesorter-headerSortUp". Original default: "headerSortUp"
cssChildRow String "tablesorter-childRow" Add this css class to a child row that should always be attached to its parent. Click on the "cssChildRow" link to toggle the view on the attached child row. Previous default was "expand-child" (Modified v2.4). 1 2
This is an entirely new row, but attached to the row above while sorting
cssChildRow Example HTML:
<table width="100%" border="1">
  <thead>
    <tr>
      <th>Item #</th>
      <th>Name</th>
      <th>Available</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>12345</td>
      <td>Toy Car</td>
      <td>5</td>
    </tr>
    <tr class="tablesorter-childRow"> <!-- this row will remain attached to the above row, and not sort separately -->
      <td colspan="3">
        It's a toy car!
      </td>
    </tr>
    <tr>
      <td>23456</td>
      <td>Toy Plane</td>
      <td>2</td>
    </tr>
    <tr class="tablesorter-childRow"> <!-- this row will remain attached to the above row, and not sort separately -->
      <td colspan="3">
        It's a toy plane!
      </td>
    </tr>
    <tr class="tablesorter-childRow"> <!-- this row will remain attached to the above two rows, and not sort separately -->
      <td colspan="3">
        and it flies!
      </td>
    </tr>
  </tbody>
</table>
					
String "" Additional CSS class applied to style the header with a descending sort (v2.11).

Changed to empty string in v2.11, as the "tablesorter-headerDesc" class will always be added to a header cell with a descending sort; this option now contains any additional class names to add.

Example from the blue theme:

.tablesorter-blue .tablesorter-headerDesc {
  background-color: #8cb3d9;
  background-image: url(black-desc.gif);
}
Default changed v2.5 to "tablesorter-headerDesc". Default changed v2.1.7 to "tablesorter-headerSortDown". Original default: "headerSortDown"
String "" Additional CSS class applied to style the headers (v2.11).

Changed to empty string in v2.11, as the "tablesorter-header" class will always be added to the table headers; this option now contains any additional class names to add.

Example from the blue theme:

.tablesorter-blue .tablesorter-header {
  background-color: #99bfe6;
  background-repeat: no-repeat;
  background-position: center right;
  padding: 4px 20px 4px 4px;
  white-space: normal;
  cursor: pointer;
}
Default changed v2.1.7 to "tablesorter-header". Original default: "header"
String "" Additional CSS class applied to style the header row (v2.11).

Changed to empty string in v2.11, as the "tablesorter-headerRow" class will always be added to a table header row; this option now contains any additional class names to add.

This CSS style was added in v2.4, prior to that the row would get the same class as the header cells. This class was added to make it easier to determine what element was being targeted in the plugin.

String "tablesorter-icon" The CSS style used to style the header cell icon (modified v2.7).

As of v2.4, an <i> element, with this class name, is automatically appended to the header cells. To prevent the plugin from adding an <i> element to the headers, set the cssIcon option to an empty string.

In v2.7, the icon will only be added to the header if both the cssIcon option is set AND the headerTemplate option includes the icon tag ({icon}).
String "" The CSS style added to the header cell icon when the column has an ascending sort (v2.18.3).

This class is only applied when the headerTemplate option includes a {icon} tag or an HTML element with the class name from the cssIcon option.
String "" The CSS style used to style the header cell icon when the column has a descending sort (v2.18.3)

This class is only applied when the headerTemplate option includes a {icon} tag or an HTML element with the class name from the cssIcon option.
String "" The CSS style used to style the header cell icon when the column does not have a sort applied (v2.18.3)

This class is only applied when the headerTemplate option includes a {icon} tag or an HTML element with the class name from the cssIcon option.
String "" Additional CSS class applied to style the header when no sort is applied (v2.15).

A "tablesorter-headerUnSorted" class will always be added to an unsorted header cell; this option contains any additional class names to add. Currently, no themes use this class name.
String "" Additional CSS class applied to style the header cell while it is being sorted or filtered (v2.4; v2.11).

Changed to empty string in v2.11, as the "tablesorter-processing" class will always be added to a table cells during processing; this option now contains any additional class names to add.

This class name is added to the header cell that is currently being sorted or filted. To prevent this class name from being added, set the showProcessing option to false.

String "tablesorter-infoOnly" All tbodies with this class name will not have its contents sorted. (v2.2).

With the addition of multiple tbody sorting in v2.2, you can now insert a non-sorting tbody within the table by adding this class to the tbody.
<tbody class="tablesorter-infoOnly">
  <tr>
    <th>The contents of this tbody</th>
  </tr>
  <tr>
    <td>will not be sorted</td>
  </tr>
</tbody>
As an example, I've split up this options table into three (3) tbodies. The first contains the active options, the second is the info block with a row that only contains the text "Deprecated Options", and the last tbody contains the deprecated options. Sort the table to see how each tbody sorts separately.

NOTE! The pager plugin will only be applied to the first tbody, as always. I may work on modifying this behavior in the future, if I can figure out the best implementation.

cssAllowClicks String "tablesorter-allowClicks" Class name added to table header which allows clicks to bubble up. (v2.18.1).
String "tablesorter-ignoreRow" Class name to add to a table header row if you want all cells within this row to be ignored (v2.18.4).

Header rows with this class name will not be added into the table.config.$headers variable.

This class name should be added to header rows that contain custom HTML, like for the pager controls, custom filter row or table toolbar.
String "mmddyyyy" Set the date format. Here are the available options. (Modified v2.0.23).
  • "mmddyyyy" (default)
  • "ddmmyyyy"
  • "yyyymmdd"
In previous versions, this option was set as "us", "uk" or "dd/mm/yy". This option was modified to better fit needed date formats. It will only work with four digit years!

The sorter should be set to "shortDate" and the date format can be set in the "dateFormat" option or set for a specific columns within the "headers" option. See the demo page to see it working.
$(function(){
  $("table").tablesorter({

    dateFormat : "mmddyyyy", // default date format

    // or to change the format for specific columns,
    // add the dateFormat to the headers option:
    headers: {
      0: { sorter: "shortDate" }, // "shortDate" with the default dateFormat above
      1: { sorter: "shortDate", dateFormat: "ddmmyyyy" }, // day first format
      2: { sorter: "shortDate", dateFormat: "yyyymmdd" }  // year first format
    }

  });
});
Individual columns can be modified by adding the following (they all do the same thing), set in order of priority (Modified v2.3.1):
  • jQuery data data-dateFormat="mmddyyyy".
  • metadata class="{ dateFormat: 'mmddyyyy'}". This requires the metadata plugin.
  • headers option headers : { 0 : { dateFormat : 'mmddyyyy' } }.
  • header class name class="dateFormat-mmddyyyy".
  • Overall dateFormat option.
Example
debug Boolean false Boolean flag indicating if tablesorter should display debuging information useful for development. Example
delayInit Boolean false Setting this option to true will delay parsing of all table cell data until the user initializes a sort. This speeds up the initialization process of very large tables, but the data still needs to be parsed, so the delay is still present upon initial sort. Example
String "bottom" Boolean flag indicating how tablesorter should deal with empty table cells. (Modified v2.1.16, v2.16.2).
  • bottom - sort empty table cells to the bottom.
  • top - sort empty table cells to the top.
  • none or zero - sort empty table cells as if the cell has the value equal to zero.
  • emptyMax - sort empty table cells as having a value greater than the max (more positive) value (v2.16.2).
  • emptyMin - sort empty table cells as having a value greater than the min (more negative) value (v2.16.2).
Individual columns can be modified by adding the following (they all do the same thing), set in order of priority:
  • jQuery data data-empty="top".
  • metadata class="{ empty: 'top'}". This requires the metadata plugin.
  • headers option headers : { 0 : { empty : 'top' } }.
  • header class name class="empty-top".
  • Overall emptyTo option.
emptyToBottom option was added in v2.1.11, then replaced by the emptyTo option in v2.1.16.
Example
Object null An object of instructions for per-"header cell" controls in the format: headers: { 0: { option: setting }, ... } (v2.17.1) docs updated

For example, to disable sorting on the first two columns of a table: headers: { 0: { sorter: false}, 1: {sorter: false} }.

The plugin attempts to detect the type of data that is contained in a column, but if it can't figure it out then it defaults to alphanumeric. You can easily override this by setting the header argument (or column parser). See the full list of default parsers here or write your own.
$(function(){
  $("table").tablesorter({
    headers: {

      // See example - Disable first header cell; parser false skips extracting content
      0: { sorter: false, parser: false },

      // See example 2: Sort column numerically & treat any text as if its value is:
      1: { sorter: "digit", empty:  "top" }, // zero; sort empty cells to the top
      2: { sorter: "digit", string: "max" }, // maximum positive value
      3: { sorter: "digit", string: "min" }, // maximum negative value

      // Sort the fifth column by date & set the format
      4: { sorter: "shortDate", dateFormat: "yyyymmdd" }, // year first format

      // See example 3: lock the sort order
      // this option will not work if added as metadata
      5: { lockedOrder: "asc" },

      // See Example 4: Initial sort order direction of seventh header cell
      6: { sortInitialOrder: "desc" },

      // Set filter widget options for this column
      // See the "Applying the filter widget" demo
      7: { filter: false },    // disable filter widget for this column
      8: { filter: "parsed" }, // use parsed data for this column in the filter search

      // Set resizable widget options for this column
      9: { resizable: false } // prevent resizing of header cell 9

    }
  });
});
Please note that the headers index values corresponds to the table header cells index (zero-based) and not the actual columns. For example, given the following table thead markup, the header-index counts the header th cells and does not actually match the data-column index when extra rows and/or colspan or rowspan are included in any of the header cells:
<thead>
	<tr>
		<th colspan="4" data-column="0">header-index 0</th>
	</tr>
	<tr>
		<th data-column="0">header-index 1</th>
		<th data-column="1">header-index 2</th>
		<th data-column="2">header-index 3</th>
		<th data-column="3">header-index 4</th>
	</tr>
	<tr>
		<th colspan="2" data-column="0">header-index 5</th>
		<th colspan="2" data-column="2">header-index 6</th>
	</tr>
</thead>
So, in the above example, to disable the sort of the second table column (data-column index of 1), the header cell of index 2 needs to be set as follows: 2 : { sorter : false }.

In v2.17.0, you can reference the column(s) using a class name, id or column index.
headers : {
    '.first-name' : { sorter: 'text' },
    '.disabled'   : { sorter: false }
}
Warning What won't work is if you try to target the header using a filtering selector that uses an index, e.g. "th:eq()", ":gt()", ":lt()", ":first", ":last", ":even" or ":odd", ":first-child", ":last-child", ":nth-child()", ":nth-last-child()", etc.
1 2 3 4 5
String "{content}" This is a template string which allows adding additional content to the header while it is being built (v2.7; v2.17.8).

In v2.17.8, if this option is set to an empty string (''), an inner div will no longer be wrapped around the header content.

This template string has two modifying tags: {content} and {icon}.
{content} will be replaced by the current header HTML content.
{icon} will be replaced by <i class="tablesorter-icon"></i>, but only if a class name is defined in the cssIcon option.

This template string may also contain HTML, e.g ('<em>{content}</em> {icon}')

After the template string is built, the onRenderTemplate function is called to allow further manipulation. Please read more about this onRenderTemplate function and/or check out the example (link to the right).
Example
ignoreCase Boolean true When true, text sorting will ignore the character case. If false, upper case characters will sort before lower case. (v2.2).
String "alt" Used by the image parser to grab the image attribute content (v2.17.5; moved to tablesorter core in v2.18.0; see config.parsers).

Change this setting to grab a different image attribute to be used for sorting:
$(function(){
  $('table').tablesorter({
    // parse image title (value to be used while sorting & filtering)
    imgAttr : 'title',
    headers : {
      0 : { sorter: 'image' } // this parser is auto-detected, but will only work on the first image
    }
  });
});
Function null This callback fires when tablesorter has completed initialization. (v2.2).
$(function(){

  // bind to tablesorter-initialized event BEFORE initializing tablesorter*
  $("table")
    .bind("tablesorter-initialized",function(e, table) {
      // do something after tablesorter has initialized
    });

  // initialize the tablesorter plugin
  $("table").tablesorter({
    // this is equivalent to the above bind method
    initialized : function(table){
      // do something after tablesorter has initialized
    }
  });

});
* Note: bind to all initialization events before initializing tablesorter; because most of the time, if bound after, the events will fire before the binding occurs.
Boolean true Apply widgets after table initializes (v2.3.5).
When true, all widgets set by the widgets option will apply after tablesorter has initialized, this is the normal behavior.

If false, the each widget set by the widgets option will be initialized, meaning the "init" function is run, but the format function will not be run. This is useful when running the pager plugin after the table is set up. The pager plugin will initialize, then apply all set widgets.

Why you ask? Well, lets say you have a table with 1000 rows that will have the pager plugin applied to it. Before this option, the table would finish its setup, all widgets would be applied to the 1000 rows, pager plugin initializes and reapplies the widgets on the say 20 rows showing; making the widget application to 100 rows unnecessary and a waste of time. So, when this option is false, widgets will only be applied to the table after the pager is set up.
String 'widget-{name}' When the table has a class name that matches the template and a widget id that matches the {name}, the widget will automatically be added to the table (v2.18.0)

By default, this option is set to 'widget-{name}'. So if the table has a class name of widget-zebra the zebra widget will be automatically added to the config.widgets option and applied to the table.

Some widget ID's with special characters may not be detected; ID's with letters, numbers, underscores and/or dashes will be correctly detected.

The template string *must* contain the {name} tag.
Function null This function is called after content is to the TH tags (after the template is procressed and added). You can use this to modify the HTML in each header tag for additional styling (v2.18.0).

In versions 2.0.6+, all TH text is wrapped in a div with a class name of "tablesorter-inner" by default. In the example below, the header cell (TH) div is given a class name (source).
Function parameters:
  • index - zero-based index of the current table header cell; this value is not indicative of the column index, as it is simply a count of header cells. So it will be effected by rowspan, colspan and multiple rows in the header.
  • config - The current table.config.
  • $table - This value is the current table jQuery object. If this function is being applied to cloned headers, as is does in the stickyHeaders widget, then this value will contain the sticky header clone added after the current table, and not the main table (v2.18.0).
$(function(){
  $("table").tablesorter({
    headerTemplate: '{content}',
    onRenderHeader: function (index, config, $table){
      $(this).find('div').addClass('roundedCorners');
    }
  });
});
and you'll end up with this HTML (only the thead is shown)
<thead>
  <tr>
    <th class="tablesorter-header"><div class="tablesorter-header-inner roundedCorners">Column 1</div></th>
    <th class="tablesorter-header"><div class="tablesorter-header-inner roundedCorners">Column 2</div></th>
  </tr>
</thead>
* Note: this function adds additional rendering time to the table if any DOM manipulation is done. Because this time will be on top of the processing time already added by the template.
Example
Function null This function is called after the template string has been built, but before the template string is applied to the header and before the onRenderHeader function is called (v2.7).

The onRenderTemplate function receives a column index and template string parameters. The template string, from the headerTemplate option, will already have the {icon} and {content} tags replaced; it's just a string of formatted HTML. When done manipulating this string, return it. Here is an example:
$(function(){
  $("table").tablesorter({
    headerTemplate: '{icon}{content}',
    onRenderTemplate: function (index, template){
      return '<em>' + (index + 1) + ':</em> ' + template;
    }
  });
});
The template parameter can be manipulated as a string, or if you prefer, turn it into a jQuery object (var $t = $(template)) to find and replace content as desired. Just make sure you return a string (return $t.html())

From the example function above, you'll end up with something similar to this HTML (only the thead is shown)
<thead>
  <tr>
    <th class="tablesorter-header"><div class="tablesorter-header-inner"><em>1:</em> <i class="tablesorter-icon"></i>First Name</div></th>
    <th class="tablesorter-header"><div class="tablesorter-header-inner"><em>2:</em> <i class="tablesorter-icon"></i>Last Name</div></th>
  </tr>
</thead>
* Note: If the cssIcon option is an empty string, the {icon} tag will also become an empty string.
Example
String "> thead th, > thead td" jQuery selectors used to find cells in the header.
You can change this, but the table will still need the required thead and tbody before this plugin will work properly.
Added > to the selector in v2.3 to prevent targetting nested table headers. It was modified again in v2.4 to include td cells within the thead.
String "tr.remove-me" This CSS class name can be applied to all rows that are to be removed prior to triggering a table update. (v2.1).

It was necessary to add this option because some widgets add table rows for styling (see the writing custom widgets demo) and if a table update is triggered ($('table').trigger('update');) those added rows will automatically become incorporated into the table.
selectorSort String "th, td" jQuery selector of content within selectorHeaders that is clickable to trigger a sort (v2.4). Example
serverSideSorting Boolean false Set to true if the server is performing the sorting. The ui and events will still be used (v2.5.3).
showProcessing Boolean false Show an indeterminate timer icon in the header when the table is sorted or filtered. Please note that due to javascript processing, the icon may not show as being animated. I'm looking into this further and would appreciate any feedback or suggestions with the coding (v2.4). Example
Array null Use to add an additional forced sort that is prepended to sortList.

For example, sortForce: [[0,0]] will sort the first column in ascending order. After the forced sort, the user selected column(s), or during initialzation, the sorting order defined in the sortList will follow. And lastly, the sort defined in the sortAppend option will be applied. More explicitly:

There are three options to determine the sort order and this is the order of priority:
  1. sortForce forces the user to have this/these column(s) sorted first (null by default).
  2. SortList is the initial sort order of the columns.
  3. SortAppend is the default sort that is added to the end of the users sort selection (null by default).
The value of these sort options is an array of arrays and can include one or more columns. The format is an array of instructions for per-column sorting and direction in the format: [[columnIndex, sortDirection], ... ] where columnIndex is a zero-based index for your columns left-to-right and sortDirection is 0 for Ascending and 1 for Descending. A valid argument that sorts ascending first by column 1 and then column 2 looks like: [[0,0],[1,0]].
$(function(){
  $("table").tablesorter({
    sortForce  : [[0,0]],        // Always sort first column first
    sortList   : [[1,0], [2,0]], // initial sort columns (2nd and 3rd)
    sortAppend : [[3,0]]         // Always add this sort on the end (4th column)
  });
});
Example
Array null Use to add an initial sort to the table.

The value contains an array of instructions for per-column sorting and direction in the format: [[columnIndex, sortDirection], ... ] where columnIndex is a zero-based index for your columns left-to-right and sortDirection is 0 for Ascending and 1 for Descending. A valid argument that sorts ascending first by column 1 and then column 2 looks like: [[0,0],[1,0]]. Please see sortForce for more details on other sort order options.
$(function(){
  $("table").tablesorter({
    sortList : [[1,0], [2,0]] // initial sort columns (2nd and 3rd)
  });
});
This option can also be set using jQuery data (v2.3.1) or metadata on the table:
** Note: data-sortlist data is not supported in jQuery versions older than 1.4.
jQuery data<table data-sortlist="[[0,0],[4,0]]"> **
Meta data<table class="tablesorter {sortlist: [[0,0],[4,0]]}">
Example
Array null Use to add an additional forced sort that will be appended to the dynamic selections by the user.

For example, can be used to sort people alphabetically after some other user-selected sort that results in rows with the same value like dates or money due. It can help prevent data from appearing as though it has a random secondary sort.

The value contains an array of instructions for per-column sorting and direction in the format: [[columnIndex, sortDirection], ... ] where columnIndex is a zero-based index for your columns left-to-right and sortDirection is 0 for Ascending and 1 for Descending. A valid argument that sorts ascending first by column 1 and then column 2 looks like: [[0,0],[1,0]]. Please see sortForce for more details on other sort order options.
Example
String "asc" This sets the direction a column will sort when clicking on the header for the first time. Valid arguments are "asc" for Ascending or "desc" for Descending.

This order can also be set by desired column using the headers option (v2.0.8).

Individual columns can be modified by adding the following (they all do the same thing), set in order of priority (modified v2.3.1):
  • jQuery data data-sortInitialOrder="asc".
  • metadata class="{ sortInitialOrder: 'asc'}". This requires the metadata plugin.
  • headers option headers : { 0 : { sortInitialOrder : 'asc' } }.
  • header class name class="sortInitialOrder-asc".
  • Overall sortInitialOrder option.
1 2
Boolean false Boolean flag indicating if certain accented characters within the table will be replaced with their equivalent characters. (Modified v2.2).
  • This option no longer switches the sort to use the String.localeCompare method.
  • When this option is true, the text parsed from table cells will convert accented characters to their equivalent to allow the alphanumeric sort to properly sort.
  • If false (default), any accented characters are treated as their value in the standard unicode order.
  • The following characters are replaced for both upper and lower case (information obtained from sugar.js sorting equivalents table):
    • áàâãä replaced with a
    • ç replaced with c
    • éèêë replaced with e
    • íìİîï replaced with i
    • óòôõö replaced with o
    • úùûü replaced with u
    • ß replaced with S
  • Please see the example page for instrcutions on how to modify the above equivalency table.
  • If you would like to continue using the String.localeCompare method, then set the sortLocaleCompare option to false and use the new textSorter option as follows:
    $('table').tablesorter({
      textSorter: function(a,b) {
        return a.localeCompare(b);
      }
    });

NOTE! See the Language wiki page for language specific examples and how to extend the character equivalent tables seen in the sortLocaleCompare demo.

Boolean flag indicating whenever to use javascript String.localeCompare method or not.
This is only used when comparing text with international character strings. A sort using localeCompare will sort accented characters the same as their unaccented counterparts.
Example
Boolean false Setting this option to true will allow you to click on the table header a third time to reset the sort direction. (v2.0.27).

Don't confuse this option with the sortReset method. This option only resets the column sort after a third click, while the method immediately resets the entire table sort.
Example
sortResetKey String "ctrlKey" The key used to reset sorting on the entire table. Defaults to the control key. The other options are "shiftKey" or "altKey" (reference).
sortRestart Boolean false Setting this option to true will start the sort with the sortInitialOrder when clicking on a previously unsorted column. (v2.0.31). Example
Boolean false Setting this option to true and sorting two rows with exactly the same content, the original sort order is maintained (v2.14).

This isn't exactly a stable sort because the sort order maintains the original unsorted order when sorting the column in an ascending direction. When sorting the column in a descending order, the opposite of the original unsorted order is returned. If that doesn't make any sense, please refer to issue #419.
sortMultiSortKey String "shiftKey" The key used to select more than one column for multi-column sorting. Defaults to the Shift key. The other options are "ctrlKey" or "altKey" (reference). Example
String "max" A key word indicating how tablesorter should deal with text inside of numerically sorted columns. (v2.1.16).

String options was initially set in the header options only. Overall option added and values changed in version 2.1.16; setting the value to:
  • "max" will treat any text in that column as a value greater than the max (more positive) value. Renamed from "max+".
  • "min" will treat any text in that column as a value greater than the min (more negative) value. Renamed from "max-".
  • "top" will always sort the text to the top of the column.
  • "bottom" will always sort the text to the bottom of the column.
  • "none" or "zero" will treat the text as if it has a value of zero.
Individual columns can be modified by adding the following (they all do the same thing), set in order of priority:
  • jQuery data data-string="top".
  • metadata class="{ string: 'top'}". This requires the metadata plugin.
  • headers option headers : { 0 : { string : 'top' } }.
  • header class name class="string-top".
  • Overall stringTo option.
Example
tabIndex Boolean true Add a tabindex to the headers for keyboard accessibility; this was previously always applied (v2.14).
String "" Additional CSS class applied to style the table (v2.11).

Changed to empty string in v2.11, as the "tablesorter" class will always be added to the table; this option now contains any additional class names to add.

This class was required in the default markup in version 2.0.5. But in version 2.0.6, it was added as an option.

Modify this option if you are not using the default css, or if you are using a completely custom stylesheet.
String "default" This option will add a theme css class name to the table "tablesorter-{theme}" for styling (v2.4; v2.18.0).

When changing this theme option, make sure that the appropriate css theme file has also been loaded. Included theme files include: see all themes
Example
String "data-text" This data-attribute can be added to any tbody cell and can contains alternate cell text (v2.16.0).

This option contains the name of the data-attribute used by the textExtraction function. Add it to the cell(s) as follows:
<td data-text="1">First repository</td>
Note This option only works when the textExtraction option is set to "basic".
String Or Function "basic" Defines which method is used to extract data from a table cell for sorting (v2.17.0)

In v2.17.0, the textExtraction column can also be referenced by using a jQuery selector (e.g. class name, id or column index) that points to a table header cell.
textExtraction : {
    // 'jQuery thead cell selector' : function ( new method )
    '.styled' : function(node, table, cellIndex) {
        return $(node).find('strong').text();
    },
    // columnIndex : function ( original method )
    2 : function(node, table, cellIndex) {
        return $(node).find('img').attr('title');
    }
}
Warning What won't work is if you try to target the header using a filtering selector that uses an index, e.g. "th:eq()", ":gt()", ":lt()", ":first", ":last", ":even" or ":odd", ":first-child", ":last-child", ":nth-child()", ":nth-last-child()", etc.

As of version 2.16.0,
  • The default text extraction method has been renamed and updated to get data from a data-attribute (set by the textAttribute option).
  • If you need to support older versions of IE, this may add a significant delay to the table initialization especially for large tables; in this case, set the textExtraction option to any name other than "basic".
  • Also, this option can now be set using a data-attribute named "data-text-extraction" on the table.
You can customize the text extraction by writing your own text extraction function "myTextExtraction" which you define like:
var myTextExtraction = function(node, table, cellIndex){
  // extract data from markup and return it
  // originally: return node.childNodes[0].childNodes[0].innerHTML;
  return $(node).find('selector').text();
}
$(function(){
  $("#myTable").tablesorter( { textExtraction: myTextExtraction } );
});
tablesorter will pass the current table cell object for you to parse and return. Thanks to Josh Nathanson for the examples; updated to a jQuery example by Rob G (Mottie).

Now if the text you are finding in the script above is say a number, then just include the headers sorter option to specify how to sort it. Also in this example, we will specify that the special textExtraction code is only needed for the second column (1 because we are using a zero-based index). All other columns will ignore this textExtraction function.

Added table and cellIndex variables to the textExtraction function in version 2.1.2 (this is not part of the original plugin).

$(function(){
  $("table").tablesorter({
    textExtraction: {
      1: function(node, table, cellIndex) {
           return $(node).find("span:last").text();
      }
    },
    headers: {
      1: { sorter : "digit" }
    }
  });
});
The built-in option is "basic" (modified v2.16.0) which is the equivalent of doing this inside of the textExtraction function: $(node).text();.
Example
String undefined This option should contain a unique namespace for each table; it is used when binding to event listeners (v2.15.7).

Notes about this namespace option:
  • If a namesspace is not defined, a (hopefully) unique random namespace will be generated.
  • If defined, any "non-word" characters (anything not "a-z", "0-9" or "_") within the namespace will be removed.
  • Added or not, the namespace will be saved with a leading period (e.g. ".myuniquetableid")
$(function(){
  $("#mytable").tablesorter({
    // if table id = "mytable", this namespace is saved as ".mytable"
    namespace : $('#mytable')[0].id;
  });
});
Function null Replace the default number sorting algorithm with a custom one using this option (v2.12).

Here is an example:
$(function(){
  $("table").tablesorter({
    numberSorter : function(a, b, direction, maxColumnValue){
      // direction; true = ascending; false = descending
      // maxColumnValue = the maximum value of that column (ignoring its sign)
      return a - b;
    }
  });
});
The direction parameter (boolean) is merely for informational purposes as the plugin automatically switches a and b depending on the sort direction ( i.e. there's no need to worry about reverse sorting, it's taken care of by the plugin ).
Function null Replace the default sorting algorithm with a custom one using this option (v2.12) - *NOTE* The parameters have changed!!.

Include a script like naturalSort.js as follows:
$(function(){
  $("table").tablesorter({
    textSorter : naturalSort
  });
});
or use the localeCompare sort
$(function(){
  $("table").tablesorter({
    // replace the OVERALL text sorter function
    textSorter: function(a, b, direction, columnIndex, table){
      // direction: true = ascending; false = descending
      // columnIndex: zero-based index of the current table column being sorted
      // table: table DOM element (access options by using table.config)
      return a.localeCompare(b);
    }
  });
});
In v2.12, the textSorter option will now accept a text sorter per column:
$(function(){
  $("table").tablesorter({
    textSorter : {
      // replace INDIVIDUAL COLUMN text sorter functions
      0 : function(a, b, direction, columnIndex, table){
        // same as $.tablesorter.sortText (basic alphabetical sort)
        // direction: true = ascending; false = descending
        // columnIndex: zero-based index of the current table column being sorted
        // table: table DOM element (access options by using table.config)
        return a > b ? 1 : (a < b ? -1 : 0);
      },
      1 : $.tablesorter.sortText,    // same as the function in column 0 above (modified in v2.12)
      2 : $.tablesorter.sortNatural, // renamed v2.12 from $.tablesorter.sortText - performs natural sort
      3 : Array.AlphanumericSort     // alphanumeric sort from sugar (http://sugarjs.com/arrays#sorting)
    }
  });
});
The direction parameter (boolean) is merely for informational purposes as the plugin automatically switches a and b depending on the sort direction ( i.e. there's no need to worry about reverse sorting, it's taken care of by the plugin ).

Boolean true Indicates how tablesorter should deal with a numerical format: (v2.1.3).
true U.S. 1,234,567.89
false German:
French:
1.234.567,89
1 234 567,89
Example
widgets Array [ ] (empty array) Initialize widgets using this option ( e.g. widgets : ['zebra'], or custom widgets widgets: ['zebra', 'myCustomWidget'];, see this demo on how to write your own custom widget ). Example
Boolean false Indicates if tablesorter should apply fixed percentage-based widths to the table columns (modified v2.4).
Prior to v2.4, this option set pixel widths to added colgroups to fix the column widths. This is useful for the Pager companion.
Requires the jQuery dimension plugin to work. This is now part of the jQuery core.
Example
Object { } In version 2.1, all widget options have been moved into this option. This is a move to store all widget specific options in one place so as not to polute the main table options. All current widgets have been modified to use this new option. (v2.1).

Previously documented widget options widgetZebra, widgetColumns and widgetUitheme will be retained for backwards compatibility.

Use the widgetOptions option as follows, please note that each option is followed by a comma (except the last one):
$(function(){

Example
Utility Options
data Object, Array undefined Storage for processed table build widget data (array, object, string) (v2.11). Example
dateRange Numeric 50 Used by the two digit year parser to set the date range (v2.14). Example
String undefined This option was added to set a specific page when storing data using the $.tablesorter.storage code (v2.12).

More specifically, when the storage function is used, it attempts to give every table a unique identifier using both the page url and table ID (or index on the page if no id exists). This option allows you to override the current page url (it doesn't need to be a url, just some constant value) and save data for multiple tables across a domain.

The table url & id can also be overridden by setting table data attributes data-table-page (url) and data-table-group (id)
(e.g. <table class="tablesorter" data-table-page="mydomain" data-table-group="financial">...</table>)

For a bit more detail, specifically on how to use the new storage function options for a custom widget, please refer to issue #389.
Deprecated Options
Object with Array { css: [ "primary", "secondary", "tertiary" ] } This option is being deprecated! It has been replaced by widgetOptions.columns; but is still available for backwards compatibility.

When the column styling widget is initialized, it automatically applied the default class names of "primary" for the primary sort, "secondary" for the next sort, "tertiary" for the next sort, and so on (add more as needed)... (v2.0.17). Use the widgetColumns option to change the css class name as follows:
$(function(){
  $("table").tablesorter({
    widgets: ["columns"], // initialize column styling of the table
    widgetColumns: { css: ["primary", "secondary", "tertiary" ] }
  });
});
Object with Array { css: [ "ui-icon-arrowthick-2-n-s", "ui-icon-arrowthick-1-s", "ui-icon-arrowthick-1-n" ] } This option is being deprecated! It has been replaced by widgetOptions.uitheme; but is still available for backwards compatibility.

Used when the ui theme styling widget is initialized. It automatically applies the default class names of "ui-icon-arrowthick-2-n-s" for the unsorted column, "ui-icon-arrowthick-1-s" for the descending sort and "ui-icon-arrowthick-1-n" for the ascending sort. (v2.0.9). Find more jQuery UI class names by hovering over the Framework icons on this page: http://jqueryui.com/themeroller/

Use the widgetUitheme option to change the css class name as follows:
$(function(){
  $("table").tablesorter({
    widgets: ["uitheme"], // initialize ui theme styling widget of the table
    widgetUitheme: {
      css: [
        "ui-icon-carat-2-n-s", // Unsorted icon
        "ui-icon-carat-1-s",   // Sort up (down arrow)
        "ui-icon-carat-1-n"    // Sort down (up arrow)
      ]
    }
  });
});
Object with Array { css: [ "even", "odd" ] } This option is being deprecated! It has been replaced by widgetOptions.zebra; but is still available for backwards compatibility.

When the zebra striping widget is initialized, it automatically applied the default class names of "even" and "odd". Use the widgetZebra option to change the css class name as follows:
$(function(){
  $("table").tablesorter({
    widgets: ["zebra"], // initialize zebra striping of the table
    widgetZebra: { css: [ "normal-row", "alt-row" ] }
  });
});

tablesorter widgets have many options, and to better organize them, they now are grouped together inside of the widgetOptions. Thanks to thezoggy for putting together this jQuery-widget compatibility table, but please note:
TIP! Click on the link in the property column to reveal full details (or toggle|show|hide all) or double click to update the browser location.
Property Type Default Description Link
Property Type Default Description Link
Array [ "primary", "secondary", "tertiary" ] Columns widget: When the column styling widget is initialized, it automatically applied the default class names of "primary" for the primary sort, "secondary" for the next sort, "tertiary" for the next sort, and so on (add more as needed)... (Modified v2.1).

Use the "columns" option to change the css class name as follows:
$(function(){
  $("table").tablesorter({
    widgets: ["columns"], // initialize column styling of the table
    widgetOptions : {
      columns: [ "primary", "secondary", "tertiary" ]
    }
  });
});
Example
Boolean true Columns widget: If true, the class names from the columns option will also be added to the table thead (v2.4).

Use the "columns_thead" option to add the column class names to the thead as follows:
$(function(){
  $("table").tablesorter({
    widgets: ["columns"], // initialize column styling of the table
    widgetOptions : {
      columns_thead: true
    }
  });
});
Example
Boolean true Columns widget: If true, the class names from the columns option will also be added to the table tfoot (v2.4).

Use the "columns_tfoot" option to add the column class names to the tfoot as follows:
$(function(){
  $("table").tablesorter({
    widgets: ["columns"], // initialize column styling of the table
    widgetOptions : {
      columns_tfoot: true
    }
  });
});
Example
Boolean false Filter widget: If there are child rows in the table (rows with class name from "cssChildRow" option) and this option is true and a match is found anywhere in the child row, then it will make that row visible. (Modified v2.1).

Use the filter_childRows option include child row text as follows:
$(function(){
  $("table").tablesorter({
    widgets: ["filter"],
    widgetOptions : {
      filter_childRows : true
    }
  });
});
Boolean true Filter widget: If true, a filter will be added to the top of each table column (v2.4).

Use the filter_columnFilters option as follows:
$(function(){
  $("table").tablesorter({
    widgets: ["filter"],
    widgetOptions : {
      filter_columnFilters : true
    }
  });
});
String or Array "" Additional CSS class applied to each filter cell (v2.18.0).

When the filter row is built, each table cell (<td>) will get the class name from this option.
  • If this option is a plain string, all filter row cells will get the text applied as a class name.
  • If this option is an array, then each filter row cell will get the text from the associate array element applied as a class name.

Use the filter_cellFilter option to add an extra css class name as follows:

$(function(){
  $("table").tablesorter({
    widgets: ["filter"],
    widgetOptions : {
      // css class applied to the table row containing the filters & the inputs within that row
      // or [ "filter-cell0", "filter-cell1", "filter-cell2", etc... ]
      filter_cellFilter : "tablesorter-filter-cell"
    }
  });
});
Note The cells from this option are also contained within the config.$filters variable.
Example
String or Array "" Additional CSS class applied to each filter (v2.15).

As of v2.15, this option can also contain an array of class names that are to be applied to input filters.

Changed to empty string in v2.11, as the "tablesorter-filter" class will always be added to the filter; this option now contains any additional class names to add.

Use the filter_cssFilter option to add an extra css class name as follows:

$(function(){
  $("table").tablesorter({
    widgets: ["filter"],
    widgetOptions : {
      // css class applied to the table row containing the filters & the inputs within that row
      // or [ "filter0", "filter1", "filter2", etc... ]
      filter_cssFilter : "tablesorter-filter"
    }
  });
});
Example
Object { } Filter widget: Add a default filter type to a column (v2.17.8).

Warning If a column has a default filter set, the user will not be able to use other filters.

Use the filter_defaultFilter option as follows:
$(function(){
  $("table").tablesorter({
    widgets: ["filter"],
    widgetOptions : {

      filter_defaultFilter : {
        // target a column by class name or column index (zero-based)

        '.fuzzy' : '~{q}',
        2 : '{q}=',

        // for default "anyMatches" use the column length as the index
        // e.g. if your table has 5 columns (0,1,2,3,4), then set the anyMatch column as 5.
        5 : '{q} or {q}' // any match column
      }

    }
  });
});
Set up the column string as follows:
  • Add the desired filter type symbol along with {query} or {q} to maintain positioning
  • Symbols can be added to the beginning "~{query}" (default fuzzy search) or end "{q}=" (default exact search)
  • For symbols that separate queries, like "AND", "OR" or "-" (range):
    • Add one additional {q} tag.
    • For example, to add a default "OR" search, use "{q} OR {q}".
    • If the user enters "a b c d" the column will be filtered using "a OR b OR c OR d", so there is no need to add more {q} tags within the string; adding more will likely mess up the results.
    • If the user only enters "a", then the column will be filtered using "a OR a" so as not to cause other issues.
  • Note It is not possible to set up a default filter search within a query. So the "wild" filter search will not work as intended (e.g. {q}* and {q}? are essentially the same as {q}.
Example
Object { } Additional CSS class applied to each filter (v2.17.8). Filter widget: Exclude a filter type(s) for a column.

Use the filter_excludeFilter option as follows:
$(function(){
  $("table").tablesorter({
    widgets: ["filter"],
    widgetOptions : {

      filter_excludeFilter : {
        // target a column by class name or column index (zero-based)
        '.title' : 'range',

        // separate multiple filter types using spaces
        2 : 'range notMatch exact'
      }

    }
  });
});
Exclusion names must be separated by a comma. Here is a full list of filter type names:
  • and - logical " AND " or && type filter.
  • exact - exact match (using " or =).
  • fuzzy - fuzzy match (~)
  • notMatch - not match (! or !=)
  • operators - comparison filters (< <= >= >)
  • range - range ( - or to )
  • regex - regex (/\d/)
  • wild - wild card matching (? for single characters, * for multiple characters not including spaces, or | or OR for a logical OR.
String "" Filter widget: jQuery selector string of inputs, outside of the table, to be used for searching table content (v2.15).

Set this option to be a jQuery selector string, or jQuery object, pointing to any external inputs that are to be used for searching the table.

Use the filter_external option as follows:
$(function(){
  $("table").tablesorter({
    widgets: ["filter"],
    widgetOptions : {
      filter_external : '.search'
    }
  });
});
These external inputs have one requirement, they must have a data-column="#", where the # targets the column (zero-based index), pointing to a specific column to search.
<input class="search" type="search" data-column="0" placeholder="Search first column">
If you want to search all columns, using the updated "any match" method, set the data column value to "all":
<input class="search" type="search" data-column="all" placeholder="Search entire table">
The updated any matching code will now automatically update all associated inputs with the latest search.
This option replaces filter_anyMatch.
Example
filter_filteredRow String "filtered" Filter widget: This is the class name applied to all rows that do not match the filter (hidden rows); used by pager plugin (v2.10).
Object null Filter widget: This option allows you to add custom controls within the filter widget row (v2.7.7; v2.17.0).

In v2.17.0, the filter_formatter column can also be referenced by using a jQuery selector (e.g. class name or ID) that points to a table header cell.
filter_formatter : {
    ".col-value" : function($cell, indx){
      return $.tablesorter.filterFormatter.uiSpinner( $cell, indx, {
        ...
      });
    }
}
Warning What won't work is if you try to target the header using a filtering selector that uses an index, e.g. "th:eq()", ":gt()", ":lt()", ":first", ":last", ":even" or ":odd", ":first-child", ":last-child", ":nth-child()", ":nth-last-child()", etc.

A new file has been included named "jquery.tablesorter.widgets-filter-formatter.js". It includes code to add jQuery UI and HTML5 controls via the filter_formatter option.

Most of the formatter functions have an option named valueToHeader which, when true adds a span to the header cell above the filter row and updates it with the current control's value (see example 2). If the option exists and is set to false, then the current value is added to the control's handle and css can be used to create a popup to show the current value (see example 1).

Another custom option named addToggle is included with the "uiSpinner", "html5Color" and "html5Number" code. This allows the user to disable the control to show all table rows. For the single sliders, "uiSlider" and "html5Range", the minimum value is used to clear the filter (show all rows).

The options included for each jQuery UI control only show basic options, but any or all of the jQuery UI options for that control can be included.
  • To add the jQuery UI slider, follow this example:
    $(function(){
      $("table").tablesorter({
        widgets: ["filter"],
        widgetOptions : {
          filter_formatter : {
            // column index `0` or use a jQuery selector `"th:contains('Discount')"`
            0 : function($cell, indx){
              return $.tablesorter.filterFormatter.uiSpinner( $cell, indx, {
                value : 0,  // starting value
                min   : 0,  // minimum value
                max   : 50, // maximum value
                step  : 1,  // increment value by
                addToggle: true, // Add a toggle to enable/disable the control
                valueToHeader: false // add current slider value to the header cell
              });
            }
          }
        }
      });
    });
    Any of the other jQuery UI spinner widget options can also be included.

  • Filter formatter functions include: "uiSpinner", "uiSlider", "uiRange" (uiSlider ranged), "uiDatepicker" (range only), "html5Number", "html5Range" and "html5Color".
  • For other examples, please refer to the example pages. Formatter part 1 (example 1) adds jQuery UI controls to the filter row, while formatter part 2 (example 2) adds HTML5 controls, if supported, to the filter row.

Object null Filter widget: Customize the filter widget by adding a select dropdown with content, custom options or custom filter functions (v2.3.6; v2.17.0).

In v2.17.0, the filter_functions column can also be referenced by using a jQuery selector (e.g. class name or ID) that points to a table header cell.
filter_functions : {
    ".col-date" : {
        "< 2004" : function (e, n, f, i) {
            return n < Date.UTC(2004, 0, 1); // < Jan 1 2004
        },
        ...
    }
}
Warning What won't work is if you try to target the header using a filtering selector that uses an index, e.g. "th:eq()", ":gt()", ":lt()", ":first", ":last", ":even" or ":odd", ":first-child", ":last-child", ":nth-child()", ":nth-last-child()", etc.

Use the "filter_functions" option in three different ways:
  • Make a sorted select dropdown list of all column contents. Repeated content will be combined.
    $(function(){
      $("table").tablesorter({
        widgets: ["filter"],
        widgetOptions: {
          filter_functions: {
            // Add select menu to this column
            // set the column value to true, and/or add "filter-select" class name to header
            0 : true
          }
        }
      });
    });
    Alternately, instead of setting the column filter funtion to true, give the column header a class name of "filter-select". See the demo.

  • Make a select dropdown list with custom option settings. Each option must have a corresponding function which returns a boolean value; return true if there is a match, or false with no match.

    Regex example

    $(function(){
      $("table").tablesorter({
        widgets: ["filter"],
        widgetOptions: {
          // function variables:
          // e = exact text from cell
          // n = normalized value returned by the column parser
          // f = search filter input value
          // i = column index
          filter_functions: {
            // Add these options to the select dropdown (regex example)
            2 : {
              "A - D" : function(e, n, f, i) { return /^[A-D]/.test(e); },
              "E - H" : function(e, n, f, i) { return /^[E-H]/.test(e); },
              "I - L" : function(e, n, f, i) { return /^[I-L]/.test(e); },
              "M - P" : function(e, n, f, i) { return /^[M-P]/.test(e); },
              "Q - T" : function(e, n, f, i) { return /^[Q-T]/.test(e); },
              "U - X" : function(e, n, f, i) { return /^[U-X]/.test(e); },
              "Y - Z" : function(e, n, f, i) { return /^[Y-Z]/.test(e); }
            }
          }
        }
      });
    });

    Comparison example

    $(function(){
      $("table").tablesorter({
        widgets: ["filter"],
        widgetOptions: {
          // function variables:
          // e = exact text from cell
          // n = normalized value returned by the column parser
          // f = search filter input value
          // i = column index
          filter_functions: {
            // Add these options to the select dropdown (numerical comparison example)
            // Note that only the normalized (n) value will contain numerical data
            // If you use the exact text, you'll need to parse it (parseFloat or parseInt)
            4 : {
              "< $10"      : function(e, n, f, i) { return n < 10; },
              "$10 - $100" : function(e, n, f, i) { return n >= 10 && n <=100; },
              "> $100"     : function(e, n, f, i) { return n > 100; }
            }
          }
        }
      });
    });
    Note: if the filter_ignoreCase option is true, it DOES alter the normalized value (n) by making it all lower case.

  • Make a custom filter for the column.
    $(function(){
      $("table").tablesorter({
        widgets: ["filter"],
        widgetOptions: {
          // function variables:
          // e = exact text from cell
          // n = normalized value returned by the column parser
          // f = search filter input value
          // i = column index
          filter_functions: {
            // Exact match only
            1 : function(e, n, f, i) {
              return e === f;
            }
          }
        }
      });
    });
    Note: if the filter_ignoreCase option is true, it DOES alter the normalized value (n) by making it all lower case.

Example
Boolean true Filter widget: Set this option to false to always show the filter row; by default, the filter row is completely hidden when no rows exist within the tbody (v2.15).

Use the filter_hideEmpty option as follows:
$(function(){
  $("table").tablesorter({
    widgets: ["filter"],
    widgetOptions : {
      filter_hideEmpty : false
    }
  });
});
Boolean false Filter widget: Set this option to true to hide the filter row initially. The row is revealed by hovering over the visible portion of the filter row or by giving any filter input/select focus (tab key) (v2.4).

Use the filter_hideFilters option as follows:
$(function(){
  $("table").tablesorter({
    widgets: ["filter"],
    widgetOptions : {
      filter_hideFilters : true
    }
  });
});
You can change the style (thickness) of the hidden filter row in the tablesorter theme css. Look for .tablesorter-filter-row (revealed row) and .tablesorter-filter-row.hideme (for the hidden row) css definitions.
Example
Boolean true Filter widget: Set this option to false to make the column content search case-insensitive, so typing in "a" will not find "Albert". (v2.3.4)

Use the filter_ignorecase option as follows:
$(function(){
  $("table").tablesorter({
    widgets: ["filter"],
    widgetOptions : {
      filter_ignoreCase : false
    }
  });
});
Example
Boolean, or Number true Filter widget: If true, a search of the column content will occur as the user types, with the delay set in the filter_searchDelay option (v2.9; v2.10).

This option, when false allows you to disable the live search behavior, so that a filter is only applied when the user presses Enter (or uses Esc to clear and cancel the search).

If this option is set to a number, e.g. 4, a search of the column content will not initiate until this minimum number of characters are entered into the input.
String "filter-onlyAvail" Filter widget: If a header contains a select dropdown and this class name, only the available (visible) options in the column will show (v2.10.1; v2.17.6).

In v2.17.6, columns with the only available class name set, that are not currently being filtered will only show the available options. Conversely, the column(s) with a selected option will show all options.

This option is useful after one or more columns have been filtered, then the column select filter with this class applied will only show the contents of the column within the dropdown that are currently visible. See the custom filter widget demo "Discount" column for an example (sort the "First Name" column first).

Caution: The main issue with this functionality is with keyboard accessibility. If the keyboard is used to select an option, only the first and default options will be available for chosing. The only way to select other options is with the mouse.
Example
object { search : '', select : '' } Filter widget: Set global filter input placeholder text for search inputs and selects (v2.16).

Any search type input added to the filter row will automatically get a placeholder attribute added, the source of this placeholder text is from the following sources, in order of priority:
  • Header cell data (table.config.$headers.eq(0).data('placeholder', 'search for...');
  • Header cell data-attribute (<th data-placeholder="Find Rank...">Rank</th>)
  • Global filter_placeholder.search setting.
The filter_placeholder.select setting adds the text to the first select option (default option to show all rows).

Note: The jquery.tablesorter.widgets-filter-formatter.js jQuery UI Datepicker Range Selector creates two inputs, so this option then includes two additional settings:

filter_placeholder : {
	search : '',
	select : '',
	from   : '', // datepicker range "from" placeholder
	to     : ''  // datepicker range "to" placeholder
}
Note: The browser must support the placeholder attribute before it will be visible.
Example
String, jQuery object null Filter widget: jQuery selector string of an element used to reset the filters (v2.4; v2.16).

When this option points to a reset element using a jQuery selector string, it is bound using event delegation. So if any additional reset elements, with the same class name, are added to the page dynamically, they will be associated with the same table.

For example, add this button (<button class="reset">Reset</button>) to the table header, or anywhere else on the page. That element will be used as a reset for all column and quick search filters (clears all fields):

Use the filter_reset option as follows:
$(function(){
  $("table").tablesorter({
    widgets: ["filter"],
    widgetOptions : {
      filter_reset : '.reset'
    }
  });
});
If this option contains a jQuery object (v2.16), clicking on any of the elements within that jQuery object will trigger a filter reset. If any additional elements with the same selector are added to the page, they will not be dynamically functional.

If either of these methods do not work as desired, simply trigger a filterReset event on the table.
Example
Boolean false Filter widget: If the storage utility is available (included with jquery.tablesorter.widgets.js file, the last applied filter is saved to storage (v2.14).

Filters saved to local storage (or cookies) will over-ride any default filters within the header data-attribute (set by the filter_defaultAttrib option and be available to the pager before any ajax calls are made.

To bypass this behavior, clear out the saved filters as follows:
$.tablesorter.storage( $('table'), 'tablesorter-filters', '' );
Example
Numeric 300 Filter widget: Set this option to the number of milliseconds to delay the search. (v2.3.4).

Use the filter_searchDelay option as follows:
$(function(){
  $("table").tablesorter({
    widgets: ["filter"],
    widgetOptions : {
      filter_searchDelay : 500
    }
  });
});
If you want to want to initialize the filter without user input, target any one of the filters and trigger a "search".
// target the first filter input
// this method will begin the search after the searchDelay time
$('input.tablesorter-filter:eq(0)').trigger('search');

// this method will begin the search immediately
$('input.tablesorter-filter:eq(0)').trigger('search', false);
In tablesorter v2.4+, the trigger can be applied directly to the table:
// refresh the widget filter; no delay
$('table').trigger('search', false);
Boolean true Filter widget: Set this option to allow searching through already filtered rows (in special conditions); this will speed up searching in large tables (v2.17.4).

To better explain this, lets do it by example. Lets say you have a column of color names and you enter "light" and results like "light blue" and "light grey" show up.

When you press the space bar, a space is added, and instead of searching though all of the colors again, the filter widget only searches through the already filtered results that started with "light". This can substantially speed up searching, especially in large tables.

But, there are some special circumstances which would make this method return incorrect results. So, this option was added to allow you to disable this feature in case one of these following conditions doesn't cover your need; but still, please report any issues!

The search through filtered results only occurs if the following conditions are met:
  • The last search (for all columns) was not completely empty - all rows will be searched anyway.
  • If there were no changes to the search from the beginning of the search string (changing the above search to "bright" will force a new search of all rows).
  • If the search does not contain a logical or ( or or |), or a range delimiter ( - or to ) within the search query.
  • If the search is not looking for an exact match (" or =) or a logical not search (!).
  • Or, if the search is using a select dropdown without a "filter-match" class name (looking for an exact match).
  • If the search does not contain an operator greater than or equal to a negative number (>=-10) or less than or equal to a positive number (<=10).
  • And lastly, only search filtered rows if all rows are not hidden.
If the debug option is set to true, then a message will appear while filtering stating the specific number of rows, or "all" rows, that are being searched.

Use the filter_searchFiltered option as follows:
$(function(){
  $("table").tablesorter({
    widgets: ["filter"],
    widgetOptions : {
      filter_searchFiltered : false
    }
  });
});
Function null Filter widget: Include a function to return an array of values to be added to the column filter select (v2.16.0; v2.17.2).

In v2.17.0, the filter_selectSource column can also be referenced by using a jQuery selector (e.g. class name or ID) that points to a table header cell.
filter_selectSource : {
  ".model-number" : [ "abc", "def", "ghi", "xyz" ]
}
Warning What won't work is if you try to target the header using a filtering selector that uses an index, e.g. "th:eq()", ":gt()", ":lt()", ":first", ":last", ":even" or ":odd", ":first-child", ":last-child", ":nth-child()", ":nth-last-child()", etc.

A column will have a filter select dropdown when a "filter-select" class name is added to the header cell, or if the filter_functions column value is set to true

This option allows using an alternate source, or customizing options of the filter select dropdown. This option can be set as follows:
  • null - this value will set the default behavior and return all table cell values from the current column.
  • An overall function - when this option is a function, it will be used for all filter selects in the table.
    $(function(){
      $("table").tablesorter({
        widgets: ["filter"],
        widgetOptions : {
          filter_selectSource : function(table, column, onlyAvail){
            // get an array of all table cell contents for a table column
            var array = $.tablesorter.filter.getOptions(table, column, onlyAvail);
            // manipulate the array as desired, then return it
            return array;
          }
        }
      });
    });
  • An object containing column keys set with a function - when the option is set in this manner, a function can be applied to a specific column
    $(function(){
      $("table").tablesorter({
        widgets: ["filter"],
        widgetOptions : {
          filter_selectSource : {
            0 : function(table, column, onlyAvail){
              return $.getJSON('ajax/options.json', function(data) {
                // return false if there is a problem and the select
                // will display the original defaults
                return data.hasOwnProperty('options') ? data.options : false;
            }
          }
        }
      });
    });
The function uses the following parameters:
  • table - table DOM element
  • column - zero-based index of the column with a filter select
  • onlyAvail - boolean indicating if the returned options should only be from available (non-filtered) rows.
Important Return an array of values which will be added to the filter select dropdown. This array will automatically be stripped of any duplicate values and sorted alphanumerically before being added to the select. If for some reason the custom filter_selectSource function does not obtain the desired array of values, return false and the original method of obtaining column cell content will be used.
Example
String '|' Filter widget: Set this option to be any separator (v2.17.6) that is to be used within the filter_selectSource returned array.

Use the filter_selectSourceSeparator option as follows:
$(function(){
  $("table").tablesorter({
    widgets: ["filter"],
    widgetOptions : {
      filter_selectSource : {
        0 : [ 'en|English', 'fr|French', 'de|German' ]
      },
      // filter_selectSource array text left of the separator is added to the option value, right into the option text
      filter_selectSourceSeparator : '|'
    }
  });
});
Results in this HTML:
<select>
	<option value=""></option>
	<option value="en">English</option>
	<option value="fr">French</option>
	<option value="de">German</option>
</select>
This also works for the filter_functions
$(function(){
  $("table").tablesorter({
    widgets: ["filter"],
    widgetOptions: {
      filter_functions: {
        // Add these options to the select dropdown (regex example)
        1 : {
          "<10|Less than 10" : function(e, n, f, i) { return n < 10; },
          "10 - 100|Between 10 & 100" : function(e, n, f, i) { return n >= 10 && n <=100; },
          ">100|Greater than 100" : function(e, n, f, i) { return n > 100; }
        }
      },
      // filter_selectSource array text left of the separator is added to the option value, right into the option text
      filter_selectSourceSeparator : '|'
    }
  });
});
Results in this HTML (this adds a data-function-name attribute to keep a reference to the associated filter_functions.
<select>
  <option value=""></option>
  <option data-function-name="&lt;10|Less than 10" value="&lt;10">Less than 10</option>
  <option data-function-name="10 - 100|Between 10 &amp; 100" value="10 - 100">Between 10 & 100</option>
  <option data-function-name="&gt;100|Greater than 100" value="&gt;100">Greater than 100</option>
</select>
Boolean false Filter widget: Set this option to true if filtering is performed on the server-side (v2.5.3).

Use the filter_serversideFiltering option as follows:
$(function(){
  $("table").tablesorter({
    widgets: ["filter"],
    widgetOptions : {
      filter_serversideFiltering : true
    }
  });
});
Boolean false Filter widget: Set this option to true to use the filter to find text from the start of the column, so typing in "a" will find "albert" but not "frank", both have a's. (v2.1).

Use the filter_startsWith option as follows:
$(function(){
  $("table").tablesorter({
    widgets: ["filter"],
    widgetOptions : {
      filter_startsWith : true
    }
  });
});
Example
Boolean false Filter widget: If true, ALL filter searches will only use parsed data (v2.4).

Use the filter_useParsedData option as follows:
$(function(){
  $("table").tablesorter({
    widgets: ["filter"],
    widgetOptions : {
      filter_useParsedData : false
    }
  });
});
  • To only use parsed data in specific columns, set this option to false and use any of the following (they all do the same thing), set in order of priority:
    • jQuery data data-filter="parsed".
    • metadata class="{ filter: 'parsed'}". This requires the metadata plugin.
    • headers option headers : { 0 : { filter : 'parsed' } }.
    • header class name class="filter-parsed".
  • Remember that parsed data most likely doesn't match the actual table cell text, 20% becomes 20 and Jan 1, 2013 12:01 AM becomes 1357020060000.
String "data-value" Filter widget: This option contains the name of the data-attribute which contains the default (starting) filter value (v2.10.8).

Use the filter_defaultAttrib option as follows:
$(function(){
  $("table").tablesorter({
    widgets: ["filter"],
    widgetOptions : {
      filter_defaultAttrib : 'data-value'
    }
  });
});
Then add the default filter value to the table header as follows:
<th data-value="<30">Age</th>
Example
String "" Sticky Headers widget: This additional CSS class applied to the sticky header row (v2.11).

Changed to empty string in v2.11, as the "tablesorter-stickyHeader" class will always be added to the sticky header row; this option now contains any additional class names to add.

Previously, this option contained the class name to be applied to the sticky header row (tr) (v2.1).

Use the "stickyHeaders" option to add an extra css class name as follows:
$(function(){
  $("table").tablesorter({
    widgets: ["stickyHeaders"],
    widgetOptions : {
      // css class name applied to the sticky header
      stickyHeaders : "tablesorter-stickyHeader"
    }
  });
});
Example
String "-sticky" Sticky Headers widget: If the table has an ID defined, the suffix from this option will be added to the ID in the cloned sticky table (v2.9).

So if your table ID is "gummy", then the cloned sticky table id becomes "gummy-sticky"

Use the "stickyHeaders_cloneId" option to change the cloned table id as follows:
$(function(){
  $("table").tablesorter({
    widgets: ["stickyHeaders"],
    widgetOptions : {
      // cloned table id suffix
      stickyHeaders_cloneId : "-clone"
    }
  });
});
Boolean true Sticky Headers widget: If this option is false and a caption exists, it will not be included in the sticky header (v2.10.8).

Use the stickyHeaders_includeCaption option as follows:
$(function(){
  $("table").tablesorter({
    widgets: ["stickyHeaders"],
    widgetOptions : {
      // cloned table id suffix
      stickyHeaders_includeCaption : false
    }
  });
});
Example
String null Sticky Headers widget: points to the table wrapper to stick the headers to while scrolling. Use this option to point to their needs (v2.14.4).

Use the stickyHeaders_attachTo option as follows:
$(function(){
  $("table").tablesorter({
    widgets: ["stickyHeaders"],
    widgetOptions : {
      // Where to attach the stickyHeaders
      stickyHeaders_attachTo : '.wrapper' // $('.wrapper') jQuery object can also be used
    }
  });
});
Example
String null Sticky Headers widget: points to the element in which to monitor for horizontal scrolling (v2.18.0).

If undefined (or null), the window element will be monitored.

Use the stickyHeaders_xScroll option as follows:
$(function(){
  $("table").tablesorter({
    widgets: ["stickyHeaders"],
    widgetOptions : {
      // jQuery selector or object to monitor horizontal scroll position (defaults: xScroll > attachTo > window)
      stickyHeaders_xScroll : '.wrapper' // $('.wrapper') jQuery object can also be used
    }
  });
});
Example
String null Sticky Headers widget: points to the element in which to monitor for vertical scrolling (v2.18.0).

If undefined (or null), the window element will be monitored.

Use the stickyHeaders_yScroll option as follows:
$(function(){
  $("table").tablesorter({
    widgets: ["stickyHeaders"],
    widgetOptions : {
      // jQuery selector or object to monitor vertical scroll position (defaults: yScroll > attachTo > window)
      stickyHeaders_yScroll : '.wrapper' // $('.wrapper') jQuery object can also be used
    }
  });
});
Example
Multiple 0 Sticky Headers widget: Set the sticky header offset from the top as a Number or jQuery selector string or object (v2.10).

If the page includes a fixed navigation bar at the top, like Bootstrap, set "stickyHeaders_offset" option to offset the sticky table header to be below the fixed navigation by setting this option using any of the following examples:
$(function(){
  $("table").tablesorter({
    widgets: ["stickyHeaders"],
    widgetOptions : {
      // apply sticky header top 30px below the top of the browser window
      stickyHeaders_offset : 30
    }
  });
});
or
stickyHeaders_offset : '.navbar-fixed-top' // jQuery selector string
or
stickyHeaders_offset : $('.navbar-fixed-top') // jQuery object
Boolean true Sticky Headers widget: Scroll table top into view after filtering (v2.16.2).

When a user searches the table using the sticky header filter row the results may reduce the number of rows so that the table would scroll up out of the viewport. So, this option scrolls the table top into view and moves the filter focus to the same input in the original header, instead of the sticky header input.

Set this option to false to prevent the page scroll after filtering the table.
Boolean true Sticky Headers widget: If true, sticky table headers will resize automatically when content is added to or removed from the table headers (v2.10).

While this option is true, a timer is initialized to check the width of every header cell every 1/4 second. If this causes lag, or any other problems, set this option to false. When this option is false, sticky table headers are unable to detect and match the width of the original table headers when content is added or removed.

Use the "stickyHeaders_addResizeEvent" option as follows:
$(function(){
  $("table").tablesorter({
    widgets: ["resizable"],
    widgetOptions : {
      // add header resize detection
      stickyHeaders_addResizeEvent : true
    }
  });
});
When the browser window is resized, the headers (original and sticky) will resize automatically no matter the value of this option.
Numeric 2 Sticky Headers widget: The zIndex added to the stickyHeaders. This option allows the user to adjust the value to their needs (v2.11).

Use the stickyHeaders_zIndex option as follows:
$(function(){
  $("table").tablesorter({
    widgets: ["stickyHeaders"],
    widgetOptions : {
      // The zIndex of the stickyHeaders, allows the user to adjust this to their needs
      stickyHeaders_zIndex : 100
    }
  });
});
Boolean true Resizable widget: If this option is set to false, resized column widths will not be saved. Previous saved values will be restored on page reload (v2.4).

Use the "resizable" option to not save the resized widths:
$(function(){
  $("table").tablesorter({
    widgets: ["resizable"],
    widgetOptions : {
      // css class name applied to the sticky header
      resizable : false
    }
  });
});
Example
Boolean false Resizable widget: If this option is set to true, a resizing anchor will be included in the last column of the table (v2.8.3).

If an anchor was included and the table is full width, the column would resize in the opposite direction which my not be intuitive to the user. So set this option as desired, but please be mindful of the user experience.

Use the "resizable_addLastColumn" option to include the last column resizer as follows:
$(function(){
  $("table").tablesorter({
    widgets: ["resizable"],
    widgetOptions : {
      // css class name applied to the sticky header
      resizable_addlastcolumn : true
    }
  });
});
Example
Array [] Resizable widget: Set this option to the starting & reset header widths (v2.15.12).

Use the "resizable_widths" option as follows:
$(function(){
  $("table").tablesorter({
    widgets: ["resizable"],
    widgetOptions : {
      // headers widths applied at initialization & resizable reset
      // this setting includes any non-resizable cells (resizable-false)
      resizable_widths : [ '10%', '10%', '50px' ]
    }
  });
});
Example
Boolean false Resizable widget: Set this option to throttle the resizable events (v2.17.4).

When false throttling of the mousemove (resizing) event is not applied.

Set this option to either true for a default 5 millisecond delay, or set it to any number less than 10 to adjust the throttling delay that is applied to the mousemove/resizing event.

Use the "resizable_widths" option as follows:
$(function(){
  $("table").tablesorter({
    widgets: ["resizable"],
    widgetOptions : {
      // set to true for a default 5ms throttling delay
      // or set to a number < 10 (more than that makes the resizing adjustment unusable
      resizable_throttle : true
    }
  });
});
Boolean true saveSort widget: If this option is set to false, new sorts will not be saved. Any previous saved sort will be restored on page reload (v2.4).

Use the "saveSort" option to not save the current sort:
$(function(){
  $("table").tablesorter({
    widgets: ["saveSort"],
    widgetOptions : {
      // if false, the sort will not be saved for next page reload
      saveSort : false
    }
  });
});
Example
String "jui" This option contains the name of the theme. Currently jQuery UI ("jui") and Bootstrap ("bootstrap") themes are supported (updated v2.4)

To modify the class names used, extend from the $.tablesorter.themes variable as follows:

// Extend the themes to change any of the default class names ** NEW **
$.extend($.tablesorter.themes.jui, {
  // change default jQuery uitheme icons - find the full list of icons
  // here: http://jqueryui.com/themeroller/ (hover over them for their name)
  table      : 'ui-widget ui-widget-content ui-corner-all', // table classes
  header     : 'ui-widget-header ui-corner-all ui-state-default', // header classes
  footerRow  : '',
  footerCells: '',
  icons      : 'ui-icon', // icon class added to the <i> in the header
  sortNone   : 'ui-icon-carat-2-n-s',
  sortAsc    : 'ui-icon-carat-1-n',
  sortDesc   : 'ui-icon-carat-1-s',
  active     : 'ui-state-active', // applied when column is sorted
  hover      : 'ui-state-hover',  // hover class
  filterRow  : '',
  even       : 'ui-widget-content', // even row zebra striping
  odd        : 'ui-state-default'   // odd row zebra striping
});
This widget option replaces the previous widgetUitheme. All theme css names are now contained within the $.tablesorter.themes variable. Extend the default theme as seen above.

The class names from the $.tablesorter.themes.{name} variable are applied to the table as indicated.

As before the jQuery UI theme applies the default class names of "ui-icon-arrowthick-2-n-s" for the unsorted column, "ui-icon-arrowthick-1-s" for the descending sort and "ui-icon-arrowthick-1-n" for the ascending sort. (Modified v2.1; Updated in v2.4). Find more jQuery UI class names by hovering over the Framework icons on this page: http://jqueryui.com/themeroller/

Use the "uitheme" option to change the css class name as follows:
$(function(){
  $("table").tablesorter({
    theme     : 'jui',       // set theme name from $.tablesorter.themes here
    widgets   : ["uitheme"], // initialize ui theme styling widget of the table
    widgetOptions: {
      uitheme : "jui"        // this is now optional in v2.7, it is overridden by the theme option
    }
  });
});
To add a new theme, define it as follows; replace "custom" with the name of your theme:
$.tablesorter.themes.custom = {
  table      : 'table',       // table classes
  header     : 'header',      // header classes
  footerRow  : '',
  footerCells: '',
  icons      : 'icon',        // icon class added to the <i> in the header
  sortNone   : 'sort-none',   // unsorted header
  sortAsc    : 'sort-asc',    // ascending sorted header
  sortDesc   : 'sort-desc',   // descending sorted header
  active     : 'sort-active', // applied when column is sorted
  hover      : 'hover',       // hover class
  filterRow  : 'filters',     // class added to the filter row
  even       : 'even',        // even row zebra striping
  odd        : 'odd'          // odd row zebra striping
}
Example
Array [ "even", "odd" ] zebra widget: When the zebra striping widget is initialized, it automatically applied the default class names of "even" and "odd". (Modified v2.1).

Use the "zebra" option to change the theme as follows:
$(function(){
  $("table").tablesorter({
    widgets: ["zebra"], // initialize zebra striping of the table
    widgetOptions: {
      zebra: [ "normal-row", "alt-row" ]
    }
  });
});
Example
Pager
Object null Target your one or more pager markup blocks by setting this option with a jQuery selector.

Note The pager widget equivalent option is within the widgetOptions and accessed via widgetOptions.pager_selectors.container; additionally you can change the class name that is applied to the pager (used within the jquery.tablesorter.pager.css file) by modifying the widgetOption.pager_css.container class name (default is "tablesorter-pager")

This is some example pager markup. It should contain all of the controls set by the multiple css-named options:
<div class="pager">
  <form>
    <img src="first.png" class="first"/>
    <img src="prev.png" class="prev"/>
    <span class="pagedisplay"></span> <!-- this can be any element, including an input -->
    <img src="next.png" class="next"/>
    <img src="last.png" class="last"/>
    <select class="pagesize">
      <option value="10">10</option>
      <option value="20">20</option>
      <option value="30">30</option>
      <option value="40">40</option>
    </select>
    <select class="gotoPage" title="Select page number"></select>
  </form>
</div>
Caution If you use buttons in your pager container, make sure the buttons include a button type (<button type="button">Next</button>) to prevent form submission and page reloading every time the button is clicked.

Use this option as follows:
$(function(){
  $("table")
    .tablesorter()
    .tablesorterPager({
      container: $(".pager")
    });
  });
});
Example
String null Set this option to include a url template to use so that the pager plugin can interact with your database (v2.1; v2.9).

Note The pager widget equivalent option is within the widgetOptions and accessed via widgetOptions.pager_ajaxUrl

The tags within the ajaxUrl string are optional. If do not want the user to change the page size, then you only need to include the page in this string:
ajaxUrl: "http://mydatabase.com?start={page}"
If you need to send your server a page offset (actual starting record number), then you'll need to use the customAjaxUrl option.

Here is an example of how to include the option, it should always be paired with an ajaxProcessing function:
$(function(){
  $("table")
    .tablesorter()
    .tablesorterPager({
      ajaxUrl: "http://mydatabase.com?page={page}&size={size}&{sortList:col}&{filterList:fcol}",
      ajaxProcessing: function(data, table, xhr){
        // do something with the ajax data
        return [ formatted_data, total_rows ];
      }
    });
});
The ajaxUrl template replaces the following tags with values from the tablesorter plugin and pager addon:
TagReplaced with
{page}Zero-based index of the current pager page
{page+1}One-based index of the current pager page (replace "+1" with any number) (e.g. {page+3}) (v2.9).
{size}Number of rows showing, or number of rows to get from the server
{sortList:col} or {sort:col} Adds the current sort to the ajax url string into a "col" array, so your server-side code knows how to sort the data (v2.4.5).
The col portion of the {sortList:col} tag can be any name string (no spaces) to indicate the name of the variable to apply. So if your current sortList is [[2,0],[3,0]], it becomes "&sort[2]=0&sort[3]=0" in the url. {sort:col} shortened tag also works (v2.9).
{filterList:fcol} or {filter:fcol} Adds the value of the current filters to the ajax url string into a "fcol" array, so your server-side code knows how to filter the data (v2.6).
The fcol portion of the {filterList:fcol} tag can be any name string (no spaces) to indicate the name of the variable to apply. So if your current filters are ['','Blue',13], it becomes "&fcol[2]=Blue&fcol[3]=13" in the url. {filter:col} shortened tag also works (v2.9).
Example
Function function(table, url) { return url; } This callback function allows you to modify the processed URL as desired (v2.8.1) docs updated.

Note The pager widget equivalent option is within the widgetOptions and accessed via widgetOptions.pager_customAjaxUrl

The customAjaxUrl function has two parameters, the table DOM element and the processed url string (all tags within the ajaxUrl have been replaced with their appropriate values).
$(function(){
  $("table")
    .tablesorter()
    .tablesorterPager({
      ajaxUrl: "http://mydatabase.com?page={page}&size={size}&{sortList:col}&{filterList:fcol}",
      ajaxProcessing: function(data, table, xhr){
        // do something with the ajax data
        return [ formatted_data, total_rows ];
      },
      // modify the url after all processing has been applied
      customAjaxUrl: function(table, url) {
        // trigger my custom event
        $(table).trigger('changingUrl');
        // send the server the current page
        return url += '&currntUrl=' + window.location.href;
      }
    });
});
In the following example, lets say your server needs a starting and ending record number instead of a page & size parameter. Use this option as follows:
$(function(){
  $("table")
    .tablesorter()
    .tablesorterPager({
      ajaxUrl: "http://mydatabase.com?{sortList:col}",
      customAjaxUrl: function(table, url) {
        var pager = table.config.pager,
          start = pager.page * pager.size,
          end = start + pager.size;
        return url += '&start=' + start + '&end=' + end;
      },
      ajaxProcessing: function(data, table, xhr){
        // do something with the ajax data
        return [ total_rows, data ];
      }
    });
});
Example
Object { dataType: 'json' } This option contains the ajax settings for the pager interaction with your database (v2.10).

Note The pager widget equivalent option is within the widgetOptions and accessed via widgetOptions.pager_ajaxObject

The ajaxObject is completely customizable, except for the url setting which is processed using the pager's ajaxUrl and customAjaxUrl options. This means you can also add a success callback function which is called after the ajax has rendered.

Your server does not need to return a JSON format, if you want to return pure HTML, set the dataType to "html" and modify the ajaxProcessing function to instead work with HTML; then return a jQuery object or apply the HTML to the table yourself.

See all possible settings in the jQuery.ajax documentation
$(function(){
  $("table")
    .tablesorter()
    .tablesorterPager({
      ajaxUrl: "http://mydatabase.com?page={page}&size={size}&{sortList:col}&{filterList:fcol}",
      ajaxObject: {
        // add more ajax settings here
        // see http://api.jquery.com/jQuery.ajax/#jQuery-ajax-settings
        dataType: 'json'
      },
      ajaxProcessing: function(data, table, xhr){
        // do something with the ajax data;
        return [ total_rows ];
      }
    });
});
Example
Boolean true Set this option to false if your table data is preloaded into the table, but you are still using ajax (v2.14.5).

Note The pager widget equivalent option is within the widgetOptions and accessed via widgetOptions.pager_processAjaxOnInit
Function null This function is required to return the ajax data obtained from your server into a useable format for tablesorter to apply to the table (v2.1, v2.17.3).

Note The pager widget equivalent option is within the widgetOptions and accessed via widgetOptions.pager_ajaxProcessing

This function was created and modified to allow you a great deal of flexibility. The only required information that this function needs to return is an array containing the total number of rows, which is needed to calculate total pages.

There are numerous examples below. Choosing which one to use is left to you. For more information, please check out related questions on Stackoverflow, in particular see this thread about how to use the different ajax options together.

In v2.10, the returned rows is now optional. And it can either be an array of arrays or a jQuery object (not attached to the table)

Process your ajax data so that the following information is returned:

Object

After tablesorter v2.17.3, this function can include a filteredRows property which will update the internal value and thus show a proper filtered row count, and update the "goto" page drop down selector appropriately.

After tablesorter v2.11, the ajaxProcessing function can return an object containing these properties, along with any extra properties. These extra properties will be available for use within the pager output string (see more details in issue #326);

So, lets say the data sent by the server looks like this:
{
    "total_rows"    : 100,
    "filtered_rows" : 75,
    "new_headers"   : [ "ID", "Name", "Data", "Value" ],
    "data"          : '<tr><td>a123</td><td>abc</td><td>xyz</td><td>999</td></tr>',
    "subject"       : "cheese",
    "tasty"         : "It's delicious!"
}
This ajaxProcessing function must return an object with "total", "headers" and "rows" properties! As before, "total" is the only required property; if the headers don't need to be changed, don't return a headers array, and if you append the rows to the table yourself within the ajaxProcessing function, you don't need to return a "rows" property.
ajaxProcessing: function(result, table, xhr){
    if (result && result.hasOwnProperty('data')) {

        // "total" is a required property!
        result.total = result["total_rows"];

        // "filteredRows" is optional - in tablesorter v2.17.3, this updates the filter row count internally
        // and updates the "goto" page dropdown selector appropriately
        result.filteredRows = result["filtered_rows"];

        // "headers" is optional. This is not needed if the table headers don't change
        result.headers = result["new_headers"];

        // "rows" is optional. No need to return this if you process and add the rows to the table yourself
        // otherwise, return an array of arrays or jQuery object (shown in this example)
        result.rows = $(result.data);

        return result;
    }
}
Now in the output string, you can also reference the extra ajax data:
output : '{startRow} to {endRow} of {filteredRows} ({totalRows}) rows about {subject} ({tasty})'

Array (total only)

After tablesorter v2.10, just build the table yourself and return the total number of rows:
ajaxProcessing: function(data, table, xhr){
  if (data && data.hasOwnProperty('rows')) {
    var r, row, c, d = data.rows,
    // total number of rows (required)
    total = data.total_rows,
    // all rows: array of arrays; each internal array has the table cell data for that row
    rows = '',
    // len should match pager set size (c.size)
    len = d.length;
    // this will depend on how the json is set up - see City0.json
    // rows
    for ( r=0; r < len; r++ ) {
      rows += '<tr class="ajax-row">'; // new row
      // cells
      for ( c in d[r] ) {
        if (typeof(c) === "string") {
          rows += '<td>' + d[r][c] + '</td>'; // add each table cell data to row
        }
      }
      rows += '</tr>'; // end new row
    }
    // find first sortable tbody, then add new rows
    table.config.$tbodies.eq(0).html(rows);
    // no need to trigger an update method, it's done internally
    return [ total ];
  }
}

Array (rows as jQuery object)

After tablesorter v2.10, return a jQuery object
ajaxProcessing: function(data, table, xhr){
  if (data && data.hasOwnProperty('rows')) {
    var r, row, c, d = data.rows,
    // total number of rows (required)
    total = data.total_rows,
    // array of header names (optional)
    headers = data.headers,
    // all rows: array of arrays; each internal array has the table cell data for that row
    rows = '',
    // len should match pager set size (c.size)
    len = d.length;
    // this will depend on how the json is set up - see City0.json
    // rows
    for ( r=0; r < len; r++ ) {
      rows += '<tr class="ajax-row">'; // new row
      // cells
      for ( c in d[r] ) {
        if (typeof(c) === "string") {
          rows += '<td>' + d[r][c] + '</td>'; // add each table cell data to row
        }
      }
      rows += '</tr>'; // end new row
    }
    // don't attach the $(rows) because it's difficult to tell old from new data
    // and no need to trigger an update method, it's done internally
    return [ total, $(rows), headers ];
  }
}
Or, if your JSON contains all the rows within a string this method will work:
ajaxProcessing: function(data, table, xhr){
  if (data && data.hasOwnProperty('rows')) {
    // data.rows would look something like this
    // '<tr><td>r0c0</td><td>r0c1</td></tr><tr><td>r1c0</td><td>r1c1</td></tr>'
    return [ data.total, $(data.rows), data.headers ];
  }
}

Array (rows as an array of arrays)

After tablesorter v2.1, this function must return an array with values in any of the following orders:
// [ total_rows (number), rows (array of arrays), headers (array; optional) ]
// or [ rows, total_rows, headers ]
// or [ total_rows, $(rows) ]
// or [ total_rows ]
[
  100, // total rows
  [
    [ "row1cell1", "row1cell2", ... "row1cellN" ],
    [ "row2cell1", "row2cell2", ... "row2cellN" ],
    ...
    [ "rowNcell1", "rowNcell2", ... "rowNcellN" ]
  ],
  [ "header1", "header2", ... "headerN" ] // optional
]
Note: In v2.14.3, the contents of the array can also contain table cell markup (i.e. "<td class='green'>+ 10%</td>").

Here is some example JSON (comments added, but not allowed in JSON) which is contained in the City0.json file:
{
  // total rows
  "total_rows": 80,
  // headers
  "cols" : [
    "ID", "Name", "Country Code", "District", "Population"
  ],
  // row data...
  "rows" : [{
    "ID": 1,
    "Name": "Kabul",
    "CountryCode": "AFG",
    "District": "Kabol",
    "Population": 1780000
  }, {
    // row 2, etc...
  }]
}
The above JSON is processed by the following code (this returns an array of array of table rows):
$(function(){
  $("table")
    .tablesorter()
    .tablesorterPager({
      ajaxUrl: "http://mydatabase.com?page={page}&size={size}",
      ajaxProcessing: function(data, table, xhr){
        if (data && data.hasOwnProperty('rows')) {
          var r, row, c, d = data.rows,
          // total number of rows (required)
          total = data.total_rows,
          // array of header names (optional)
          headers = data.cols,
          // all rows: array of arrays; each internal array has the table cell data for that row
          rows = [],
          // len should match pager set size (c.size)
          len = d.length;
          // this will depend on how the json is set up - see City0.json
          // rows
          for ( r = 0; r < len; r++ ) {
            row = []; // new row array
            // cells
            for ( c in d[r] ) {
              if (typeof(c) === "string") {
                row.push(d[r][c]); // add each table cell data to row array
              }
            }
            rows.push(row); // add new row array to rows array
          }
          return [ total, rows, headers ]; // or return [ rows, total, headers ] in v2.9+
        }
      }
    });
});
Example
String "{page}/{totalPages}" This option allows you to format the output display which can show the current page, total pages, filtered pages, current start and end rows, total rows and filtered rows (v2.0.9; v2.17.6).

Note The pager widget equivalent option is within the widgetOptions and accessed via widgetOptions.pager_output

This option replaced the original separator option, which only separated the page number from the total number of pages. The formatted output from this option is placed inside the information block targeted by the cssPageDisplay option.

Use it as follows:
$(function(){
  $("table")
    .tablesorter()
    .tablesorterPager({
      output: '{startRow} to {endRow} of {totalRows} rows'
    });
  });
});
The following tags are replaced within the output string:
TagReplaced with
{page}The current pager page
{page:input}The current pager page within an input (v2.17.6)
{totalPages}Total number of pager pages
{filteredPages}Total number of pages left after being filtered
{startRow}Starting row number currently displayed
{startRow:input}Starting row number currently displayed within an input (v2.17.6)
{endRow}Ending row number currently displayed
{filteredRows}Total number of rows left after being filtered
{totalRows}Total number of rows
1 2 3 4
Boolean true If true, the addon hides the left pager arrow on the first page and right pager arrow on the last page.

Note The pager widget equivalent option is within the widgetOptions and accessed via widgetOptions.pager_updateArrows

If true the classname from the cssDisabled option is applied to the arrows when at either page extreme.
Example
Numeric 0 Set the starting page of the pager (zero-based index).

Note The pager widget equivalent option is within the widgetOptions and accessed via widgetOptions.pager_startPage
Example
Numeric, Boolean 0 Reset pager to this page after filtering; set to desired page number (zero-based index), or false to not change page at filter start (v2.16).

Note The pager widget equivalent option is within the widgetOptions and accessed via widgetOptions.pager_pageReset
Numeric 10 Set initial number of visible rows. This value is changed by the dropdown selector targeted by the cssPageSize option.

Note The pager widget equivalent option is within the widgetOptions and accessed via widgetOptions.pager_size
Example
Boolean true Saves the current pager page size and number. This option requires the $.tablesorter.storage script in the jquery.tablesorter.widgets.js file (v2.11).

Note The pager widget equivalent option is within the widgetOptions and accessed via widgetOptions.pager_savePages
Example
String "tablesorter-pager" Saves tablesorter paging to custom key if defined. Key parameter name used by the $.tablesorter.storage function. Useful if you have multiple tables defined (v2.15)

Note The pager widget equivalent option is within the widgetOptions and accessed via widgetOptions.pager_storageKey
Example
Boolean false Maintain the height of the table even when fewer than the set number of records is shown (v2.1; updated 2.7.1).

Note The pager widget equivalent option is within the widgetOptions and accessed via widgetOptions.pager_fixedHeight

This option replaced the original positionFixed and offset options which set the absolute position of the pager block.

If true, it should maintain the height of the table, even when viewing fewer than the set number of records (go to the last page of any demo to see this in action). It works by adding an empty row to make up the differences in height.
Example
Boolean false If true, child rows will be counted towards the pager set size (v2.13).

Note The pager widget equivalent option is within the widgetOptions and accessed via widgetOptions.pager_countChildRows

*CAUTION* When true, child row(s) may not appear to be attached to its parent row, may be split across pages or may distort the table if rowspan or cellspans are included within the child row.

If this option is false, child row(s) will always appear on the same page as its parent.
Boolean false If true, rows are removed from the table to speed up the sort of large tables (v2.0.21).

Note The pager widget equivalent option is within the widgetOptions and accessed via widgetOptions.pager_removeRows

The original tablesorter plugin (v2.0.5) removed rows automatically, without providing an option. It really does speed up sorting of very large tables, but also breaks updating and modifying table content dynamically.

If this option is false, the addon only hides the non-visible rows; this is useful if you plan to add/remove rows with the pager enabled.
Example
String ".first" This option contains a jQuery selector string pointing to the go to first page arrow. See container for full HTML.

Note The pager widget equivalent option is within the widgetOptions and accessed via widgetOptions.pager_selectors.first
Example
String ".prev" This option contains a jQuery selector string pointing to the go to previous page arrow. See container for full HTML.

Note The pager widget equivalent option is within the widgetOptions and accessed via widgetOptions.pager_selectors.prev
Example
String ".next" This option contains a jQuery selector string pointing to the go to next page arrow. See container for full HTML.

Note The pager widget equivalent option is within the widgetOptions and accessed via widgetOptions.pager_selectors.next
Example
String ".last" This option contains a jQuery selector string pointing to the go to last page arrow. See container for full HTML.

Note The pager widget equivalent option is within the widgetOptions and accessed via widgetOptions.pager_selectors.last
Example
String ".gotoPage" This option contains a jQuery selector string pointing to the page select dropdown. See container for full HTML (v2.4; v2.17.3)

Note The pager widget equivalent option is within the widgetOptions and accessed via widgetOptions.pager_selectors.gotoPage (changed from goto in v2.17.3)

Please note that this select dropdown is initially empty and automatically updated by the plugin with the correct number of pages, which depends on the size setting.
Example
String ".pagedisplay" This option contains a jQuery selector string pointing to the output element (v2.0.9)

Note The pager widget equivalent option is within the widgetOptions and accessed via widgetOptions.pager_selectors.pageDisplay

In the original tablesorter (v2.0.5) this option could only target an input, it was updated (v2.0.9) to display the formatted output from the output option inside of any element (span, div or input).
Example
String ".pagesize" This option contains a jQuery selector string pointing to the page size selector. See container for full HTML.

Note The pager widget equivalent option is within the widgetOptions and accessed via widgetOptions.pager_selectors.pageSize
Example
String "tablesorter-errorRow" This option contains the class name that is applied to the error information row that is added inside the pager with any ajax exceptions.

Note The pager widget equivalent option is within the widgetOptions and accessed via widgetOptions.pager_css.errorRow

Note there is no period "." in front of this class name (it is not a selector).
String "disabled" This option contains the class name that is applied to disabled pager controls.

Note The pager widget equivalent option is within the widgetOptions and accessed via widgetOptions.pager_css.disabled

More explicitly, this class is applied to the pager arrows when they are at either extreme of pages and the updateArrows option is true. When the pager has been disabled, this class is applied to all controls.

Note there is no period "." in front of this class name (it is not a selector).
Removed Options
Boolean false Filter widget: This option was removed in v2.15... sorry for the sudden notice.

This option has been replaced by the filter_external option.

Show any rows that match a search query. If this option is true any column match will show that row; but there are limitations (v2.13.3).

It is best if this filter_anyMatch option is used with a single search input as follows:
<input class="search" type="search">
<button type="button" class="reset">Reset Search</button>
$(function(){
  $("table").tablesorter({
    widgets: ["filter"],
    widgetOptions : {
      filter_anyMatch : true,
      filter_columnFilters: false,
      filter_reset: '.reset'
    }
  });

  // Target the $('.search') input using built in functioning
  // this binds to the search using "search" and "keyup"
  // Allows using filter_liveSearch or delayed search &
  // pressing escape to cancel the search
  $.tablesorter.filter.bindSearch( $table, $('.search') );

});
Numeric 0 This pager plugin option has been removed!

The original tablesorter pager plugin absolutely positioned the pager controls at the bottom of the table. It appears that this option was intended to tweak the position of the pager container. The option exists, but no code was found.
Boolean true This pager plugin option has been removed!

If this option were true, the original tablesorter pager plugin would absolutely position the pager controls at the bottom of the table.
String "/" This pager plugin option has been removed! Use the output option to allow for more control over the formatting.

The original tablesorter pager plugin would combine the current page with the calculated total number of pages within the cssPageDisplay with this separator string inbetween.

Methods

tablesorter has some methods available to allow updating, resorting or applying widgets to a table after it has been initialized.
TIP! Click on the link in the method column to reveal full details (or toggle|show|hide all) or double click to update the browser location.
Method Description Link
Use this method to add table rows (v2.0.16; v2.16.2).

It does not work the same as "update" in that it only adds rows, it does not remove them.

Also, use this method to add table rows while using the pager plugin. If the "update" method is used, only the visible table rows continue to exist.
// Add multiple rows to the table
  var row = '<tr><td>Inigo</td><td>Montoya</td><td>34</td>' +
    '<td>$19.99</td><td>15%</td><td>Sep 25, 1987 12:00PM</td></tr>',
    $row = $(row),
    // resort table using the current sort; set to false to prevent resort, otherwise
    // any other value in resort will automatically trigger the table resort.
    // A callback method was added in 2.3.9.
    resort = true,
    callback = function(table){
      alert('rows have been added!');
    };
  $('table')
    .find('tbody').append($row)
    .trigger('addRows', [$row, resort, callback]);
In v2.16.1, the $row parameter can be an HTML string, row DOM element or jQuery object.
Example
Use this method reset the table to it's original settings. (v2.17.0).
Using this method will clear out any settings that have changed since the table was initialized (refreshes the entire table); so any sorting or modified widget options will be cleared.
However, it will not clear any values that were saved to storage. This method is basically like reloading the page.
$('table').trigger('resetToLoadState');
Use this method to initialize a sort while targeting a specific column header (v2.9).
// Target a specific header
$('table').find('th:eq(2)').trigger('sort');
Using this method will maintain the sorting order; so, if the column is already sorted in ascending order, this method will act as if you manually clicked on the header. Whatever sort order is applied is dependent on other option settings such as initialSortOrder, lockedOrder (set within the headers), sortReset option, sortRestart and will be ignored if the column sort is disabled (sorter: false).
Use this method to sort an initialized table in the desired order (v2.17.0)
// Choose a new sort order
var sort = [[0,0],[2,0]],
    callback = function(table){
        alert('new sort applied to ' + table.id);
    };
// Note that the sort value below is inside of another array (inside another set of square brackets)
// without a callback it could look like this:
$("table").trigger("sorton", [ [[0,0],[2,0]] ]);

// when including a callback method the outer square bracket wrap both parameters (added in 2.3.9).
$("table").trigger("sorton", [sort, callback]);
*NOTE* using this method to sort ignores the additions from the sortForce and sortAppend options.

In v2.17.0, the sort direction can be set using "a" (ascending), "d" (descending), "n" (next), "s" (same) & "o" (opposite).
$('table').trigger('sorton', [ [[0,"a"],[2,"n"]] ]);
Please try out the demo (example link) to better understand how these values work.
Example
Use this method to reset the table to it's initial unsorted state (v2.4.7; v2.16.0).

This method immediately resets the entire table sort, while the option only resets the column sort after a third click.

In v2.16.0, a callback function was added to this method.

// Reset the table (make it unsorted)
var callback = function(table) {
	console.log('sort has been reset');
};
$("table").trigger("sortReset", [callback]);
*NOTE* Don't confuse this method with the sortReset option.
Example
/ Update the tbody's stored data (update & updateRows do exactly the same thing)

// Add new content
$("table tbody").append(html);

// let the plugin know that we made a update
// the resort flag set to anything BUT false (no quotes) will trigger an automatic
// table resort using the current sort
// A callback method was added in 2.3.9.
var resort = true,
    callback = function(table){
        alert('new sort applied');
    };
$("table").trigger("update", [resort, callback]);

// As of version 2.0.14, the table will automatically resort after the update (if the "resort" flag is true
// & will use the current sort selection), so include the following if you want to specify a different sort

// set sorting column and direction, this will sort on the first and third column
var sorting = [[2,1],[0,0]];
$("table")
	.trigger("update", [ false ])
	.trigger("sorton", [sorting]);
NOTE Don't confuse this method with the sortReset option. updateRows was added to work around the issue of using jQuery with the Prototype library. Triggering an "update" would make Prototype clear the tbody; Please see issue #217 for more details.
Example
Update a column of cells (thead and tbody) (v2.8).
// Change thead & tbody column of cells
// remember, "eq()" is zero based & "nth-child()" is 1 based
$("table thead th:eq(2)").html("Number");
// add some random numbers to the table cell
$("table tbody").find('td:nth-child(3)').html(function(i,h){
  return Math.floor(Math.random()*10) + 1; // random number from 0 to 10
});

var resort = true, // re-apply the current sort
  callback = function(table){
    alert('table updated!');
  };

// let the plugin know that we made a update, then the plugin will
// automatically sort the table based on the header settings
$("table").trigger("updateAll", [ resort, callback ]);
Example
Update the parsers, only if not defined, then update the internal cache (v2.15.4).

This method is used by the pager (addon & widget) to update the data stored within the cache after the content has been updated using ajax.
$("table").trigger("updateCache");
Example
Adds all of the cached table rows back into the table.

This method was originally designed to be used with the pager. It should be used under these conditions:
  • When the pager removeRows option is true.
  • When not using the "updateCell" or "addRows" methods.
  • Before manually adding or removing table rows.
  • And, before triggering an "update".
Note: The entire table is stored in the cache, but when using the pager with the removeRows option set to true, only the visible portion is actually exists within the table. So, use this option to add all stored rows back into the table before manually changing the contents. Otherwise, if any update method is triggered, only the visible rows will be added back to the cache.
// how to update the table contents
$("table")
  .trigger("appendCache")
  .append('<tr>...</tr>') // add new row(s), or delete rows
  .trigger("update"); // update the cache
Update a table cell in the tablesorter data.
$(function() {
  $("table").tablesorter();

  $("td.discount").click(function(){

        // Do we want to reapply the current sort on the column?
    var resort = false,
        // Do something after the cell update in this callback function
        callback = function(table){
          /* do something */
        },
        // randomize a number & add it to the cell
        discount = '$' + Math.round(Math.random() * Math.random() * 100) + '.' +
          ('0' + Math.round(Math.random() * Math.random() * 100)).slice(-2);

    // add new table cell text
    $(this).text(discount);

    // update the table, so the tablesorter plugin can update its value
    // set resort flag to false to prevent automatic resort (since we're using a different sort below)
    // leave the resort flag as undefined, or with any other value, to automatically resort the table
    // $("table").trigger("updateCell", [this]); < - resort is undefined so the table WILL resort
    $("table").trigger("updateCell", [this, resort, callback]);

    // As of version 2.0.14, the table will automatically resort (using the current sort selection)
    // after the update, so include the following if you want to specify a different sort

    // set sorting column and direction, this will sort on the first and third column
    var sorting = [[3,1]];
    $("table").trigger("sorton", [sorting]);

    return false;
  });
});
Example
Apply the selected widget to the table, but the widget will not continue to be applied after each sort. See the example, it's easier than describing it.
$(function(){
  // initialize tablesorter without the widget
  $("table").tablesorter();

  // click a button to apply the zebra striping
  $("button").click(function(){
    $('table').trigger('applyWidgetId', ['zebra']);
    return false;
  });

});
Example
Apply the set widgets to the table (v2.16.0).
This method can be used after a table has been initialized, but it won't work unless you update the configuration settings. See the example, it's easier than describing it.
// Update the list of widgets to apply to the table (add or remove)
// $("table").data("tablesorter").widgets = ["zebra"]; // works the same as
$("table")[0].config.widgets = ["zebra"];

// This method applies the widget - no need to keep updating
$('table').trigger('applyWidgets');
Example
Use this method to remove tablesorter from the table (v2.3.2; v2.16).
// Remove tablesorter and all classes
$("table").trigger("destroy");

// Remove tablesorter and all classes but the "tablesorter" class on the table
// callback is a function
$("table").trigger("destroy", [false, callback]);
Refresh the currently applied widgets. Depending on the options, it will completely remove all widgets, then re-initialize the current widgets or just remove all non-current widgets (v2.4).

Trigger this method using either of the following methods (they are equivalent):
// trigger a refresh widget event
$('table').trigger('refreshWidgets', [doAll, dontapply]);

// Use the API directly
$.tablesorter.refreshWidgets(table, doAll, dontapply)
  • If doAll is true it removes all widgets from the table. If false only non-current widgets (from the widgets option) are removed.
  • When done removing widgets, the widget re-initializes the currently selected widgets, unless the dontapply parameter is true leaving the table widget-less.
  • Note that if the widgets option has any named widgets, they will be re-applied to the table when it gets resorted. So if you want to completely remove all widgets from the table, also clear out the widgets option $('table')[0].config.widgets = [];
Example
Widget Methods
filter: Trigger the filter widget to reset the search criteria (v2.7.7).

If you are using the filter_formatter option to add custom input elements, this function may not work on those columns. Please refer to the filter_formatter section for more details.
$(function(){
  // this is the same code that the "filter_reset" element runs to clear out the filters.
  $('button').click(function(){
    $('table').trigger('filterReset');
    return false;
});
This method is used by the filter_reset option when defined.
Example
Trigger the saveSort widget to clear any saved sorts for that specific table (v2.7.11).
$(function(){
  $('button').click(function(){
    $('table').trigger('saveSortReset');
    return false;
  });
});
Pager Methods
Trigger the pager to change the page size (v2.7.4).
$(function(){
  $('table').trigger('pageSize', 15);
});
Trigger the pager to change the current page (v2.7.7).
$(function(){
  $('table').trigger('pageSet', 3);
});
Calling this method will reveal the entire table, remove the pager functionality, and hide the actual pager (v2.0.16).
$(function(){
  $('table').trigger('destroy.pager');
});
The only way to restore the pager is to re-initialize the pager addon
$(function(){
  $('table').tablesorterPager(pagerOptions);
});
Example
This method will put the pager into a disabled state (v2.0.21.2).

The disabled state will reveal all table rows and disable, but not hide, pager controls.
$(function(){
  $('table').trigger('disable.pager');
});
Example
This method will re-enable the pager, but only from the disabled state (v2.0.21.2).
$(function(){
  $('table').trigger('enable.pager');
});
Example

Events

tablesorter has some methods available to allow updating, resorting or applying widgets to a table after it has been initialized.
TIP! Click on the link in the event column to reveal full details (or toggle|show|hide all) or double click to update the browser location.
Event Description Link
This event fires when tablesorter has completed initialization. (v2.2).
$(function(){

  // bind to initialized event BEFORE initializing tablesorter*
  $("table")
    .bind("tablesorter-initialized",function(e, table) {
      // do something after tablesorter has initialized
    });

  // initialize the tablesorter plugin
  $("table").tablesorter({
    // this is equivalent to the above bind method
    initialized : function(table){
      // do something after tablesorter has initialized
    }
  });

});
* Note: bind to all initialization events before initializing tablesorter; because most of the time, if bound after, the events will fire before the binding occurs.
This event fires immediately before tablesorter begins resorting the table.
$(function(){

  // initialize the tablesorter plugin
  $("table").tablesorter();

  // bind to sort events
  $("table").bind("sortBegin",function(e, table) {
    // do something crazy!
  });
});
This event fires immediately after the tablesorter header has been clicked, initializing a resort.
$(function(){

  // initialize the tablesorter plugin
  $("table").tablesorter();

  // bind to sort events
  $("table")
    .bind("sortStart",function(e, table) {
      $("#overlay").show();
    })
    .bind("sortEnd",function(e, table) {
      $("#overlay").hide();
    });
});
Example
This event fires when tablesorter has completed resorting the table.
$(function(){

  // initialize the tablesorter plugin
  $("table").tablesorter();

  // bind to sort events
  $("table")
    .bind("sortStart",function(e, table) {
      $("#overlay").show();
    })
    .bind("sortEnd",function(e, table) {
      $("#overlay").hide();
    });
});
Example
This event fires after tablesorter has completed updating. (v.2.3.9)
This occurs after an "update", "updateAll", "updateCell" or "addRows" method was called, but before any callback functions are executed.
$(function(){

  // initialize the tablesorter plugin
  $("table").tablesorter();

  // bind to sort events
  $("table")
    .bind("updateComplete",function(e, table) {
      // do something after the table has been altered;
    });
});
Widget Events
Event triggered when the filter widget has finished initializing (v2.4).

You can use this event to modify the filter elements (row, inputs and/or selects) as desired. Use it as follows:
$(function(){
  $('table')

    // bind to filter initialized event BEFORE initializing tablesorter*
    .bind('filterInit', function(){
      $(this).find('tr.tablesorter-filter-row').addClass('fred');
    })

     // initialize the sorter
    .tablesorter({
      widgets : ['filter']
    });

});
* Note: bind to all initialization events before initializing tablesorter; because most of the time, if bound after, the events will fire before the binding occurs.
Example
Event triggered when the filter widget has started processing the search (v2.4).

You can use this event to do something like add a class to the filter row. Use it as follows:
$(function(){
  $('table').bind('filterStart', function(){
    $(this).find('tr.tablesorter-filter-row').addClass('filtering');
  });
});
Example
Event triggered when the filter widget has finished processing the search (v2.4).

You can use this event to do something like remove the class added to the filter row when the filtering started. Use it as follows:
$(function(){
  $('table').bind('filterEnd', function(event, config){
    $(this).find('tr.tablesorter-filter-row').removeClass('filtering');
  });
});
Example
Event triggered when the stickyHeader widget has finished initializing (v2.10.4).

You can use this event to do something like modify content within the sticky header:
$(function(){
  $('table')
    // bind to the init event BEFORE initializing tablesorter*
    .bind('stickyHeadersInit', function(){
      // this.config.widgetOptions.$sticky contains the entire sticky header table
      this.config.widgetOptions.$sticky.find('tr.tablesorter-headerRow').addClass('sticky-styling');
    })

  // initialize the tablesorter plugin
  .tablesorter({
    widgets : ['stickyHeaders']
  });

});
* Note: bind to all initialization events before initializing tablesorter; because most of the time, if bound after, the events will fire before the binding occurs.
Pager Events
This event fires when the pager plugin begins to render the table on the currently selected page. (v2.0.7).
$(function(){

  // initialize the sorter
  $("table")
    .tablesorter()

    // initialize the pager plugin
    .tablesorterPager({
      container: $("#pager")
    })

    // bind to pager events
    .bind('pagerChange pagerComplete', function(event, options){
      // options = table.config.pager (pager addon)
      // options = table.config (pager widget) - so use options.pager.page below
      // c.totalPages contains the total number of pages
      $('#display').html( event.type + " event triggered, now on page " + (options.page + 1) );
    });

});
Example
This event fires when the pager plugin has completed initialization (v2.18.1), and its render of the table on the currently selected page. (v2.0.7).

Note In v2.18.1, the "pagerComplete" event also fires off immediately after pager initialization.

$(function(){

  // initialize the sorter
  $("table")
    .tablesorter()

    // initialize the pager plugin
    .tablesorterPager({
      container: $("#pager")
    })

    // bind to pager events
    .bind('pagerChange pagerComplete', function(event, options){
      // options = table.config.pager (pager addon)
      // options = table.config (pager widget) - so use options.pager.page below
      // c.totalPages contains the total number of pages
      $('#display').html( event.type + " event triggered, now on page " + (options.page + 1) );
    });

});
Example
This event fires after all pager controls have been bound and set up but before the pager formats the table or loads any ajax data (v2.4.4).
$(function(){

  $("table")

    // bind to pager initialized event BEFORE calling the ADDON
    // or BEFORE initializing tablesorter when using the pager WIDGET*
    .bind('pagerBeforeInitialized', function(event, options){
      // options = table.config.pager (pager addon)
      // options = table.config (pager widget)

      // event = event object; options = pager options
    })

    // initialize the sorter
    .tablesorter()

    // initialize the pager plugin
    .tablesorterPager({
      container: $("#pager")
    });

});
* Note: bind to all initialization events before initializing tablesorter; because most of the time, if bound after, the events will fire before the binding occurs.
This event fires when the pager plugin has completed initialization (v2.4.4).
$(function(){

  $("table")

    // bind to pager initialized event BEFORE calling the ADDON
    // or BEFORE initializing tablesorter when using the pager WIDGET*
    .bind('pagerInitialized', function(event, options){
      // options = table.config.pager (pager addon)
      // options = table.config (pager widget) - so use options.pager.page below
      // c.totalPages contains the total number of pages
      $('#display').html( e.type + " event triggered, now on page " + (options.page + 1) );
    })

    // initialize the sorter
    .tablesorter()

    // initialize the pager plugin
    .tablesorterPager({
      container: $("#pager")
    });

});
* Note: bind to all initialization events before initializing tablesorter; because most of the time, if bound after, the events will fire before the binding occurs.
Example
This event fires when the pager plugin begins to change to the selected page (v2.4.4).
This event may fire before the pagerComplete event when ajax processing is involved, or after the pagerComplete on normal use. See issue #153.
$(function(){

  // initialize the sorter
  $("table")
    .tablesorter()

    // initialize the pager plugin
    .tablesorterPager({
      container: $("#pager")
    })

    // bind to pager events
    .bind('pageMoved', function(event, options){
      // options = table.config.pager (pager addon)
      // options = table.config (pager widget) - so use options.pager.page below
      // c.totalPages contains the total number of pages
      $('#display').html( event.type + " event triggered, now on page " + (options.page + 1) );
    });

});

Tablesorter API

tablesorter has some useful internal variables & functions available through the API which can be used in custom coding, parsers and/or widgets.

Variables

TIP! Click on the link in the variable column to reveal full details (or toggle|show|hide all) or double click to update the browser location.
Variable Type Description Link
Array This is an array of all parser objects added using the addParser function.

If a specific parser needs to be retreived from this array, use the getParserById function.
$.tablesorter.themes Object This is an object containing a list of specific class names to be applied to table elements. Please see the widget uitheme option for more details.
Array This is an array of all widget objects added using the addWidget function.

If a specific widget needs to be retreived from this array, use the getWidgetById function.
Object This object contains the phrases (in English by default) added to the aria-label on each header column.

This is how the object is set up:
$.tablesorter.language = {
  sortAsc  : 'Ascending sort applied, ',
  sortDesc : 'Descending sort applied, ',
  sortNone : 'No sort applied, ',
  nextAsc  : 'activate to apply an ascending sort',
  nextDesc : 'activate to apply a descending sort',
  nextNone : 'activate to remove the sort'
};
So, as an example, in the following situation:
  • A table header is named "Account #"
  • This column has an ascending sort applied
  • The next click on the header will be a descending sort, which means:
    • sortInitialOrder option has its default setting; so the sort order will switch from ascending to descending on the second click.
    • No lockedOrder is set within the headers option
Then the label will be built as follows:
// "Header Name" + $.tablesorter.language.sortAsc + $.tablesorter.language.nextDesc
"Account #: Ascending sort applied, activate to apply a descending sort"
If the next click were to reset the sort (sortReset applied), then the message would use $.tablesorter.language.nextNone.

Use this variable to change the language as follows:
$(function(){

  $.tablesorter.language = {
    sortAsc  : "sorting from a to z, ",
    sortDesc : "sorting from z to a, ",
    sortNone : "not sorted, but ",
    nextAsc  : "click to sort from a to z",
    nextDesc : "click to sort from z to a",
    nextNone : "click to clear the sort"
  }
  $("table").tablesorter();
});
Access the table configuration variables (config) using any of these methods:

// pure js, get the first table (zero index)
var config = document.getElementsByTagName('table')[0].config;
// or by table ID
var config = document.getElementById('mytable').config;

// using jQuery, get first table (zero index)
var config = $('table')[0].config;
// or from the jQuery data
var config = $('#mytable').data('tablesorter');
Object Internal list of table contents (v2.0.18; v2.16.0 )

This object contains the following:
  • tbody index
    • colMax
      • This contains an array of the absolute value maximum numerical value for each "numerically" parsed column per tbody.
      • Text columns will have an undefined value in this array.
      • Used when determining how to sort text within a numeric column.
      • Access it as follows:
        // $('table')[0].config.cache[tbodyIndex].colMax[column];
        // try this in the console for this page:
        $('.tablesorter')[0].config.cache[0].colMax;
        // result: [undefined × 3, 45, 153.19, 44.7, 100.9, 1169133120000]
    • normalized
      • This contains an array of indexed table rows.
      • Within each row is an array of extracted, then parsed table contents for each column (plus one extra value; see the next comment).
      • It is important to note that the last value in the column array is the original row index value. This is used when resetting a column sort to its original unsorted order.
      • In v2.16.0, the last value in the column array is now an object which contains a jquery object of the row, index of the original unsorted order and a child array which contains raw html from any associated child row
        // $('table')[0].config.cache[tbodyIndex].normalized[row][column]
        // try this in the console for this page:
        $('.tablesorter')[0].config.cache[0].normalized[0];
        /* result: ["a1", "bruce", "almighty", 45, 153.19, 44.7, 77, 979830720000, {
            $row  : jQuery.fn.jQuery.init[1], // row (jQuery object)
            child : [], // child row raw html, if any
            order : 3   // original row index (unsorted)
        }]
        */
        to specifically target the extra row data, use this method:
        var config = $('.tablesorter')[0].config,
            dataIndex = config.columns, // number of columns within the table
            rowData = config.cache[tbodyIndex].normalized[row][ dataIndex ];
      • Note that all text values will be in lower case if the ignoreCase option is true.
      • This internal normalized content is what is actually sorted for maximum performance.
    • row (removed in v2.16.0)
      • Well not removed, but moved into the row data, within the normalized section of the cache as described above.
      • This contains an array of jQuery row objects.
      • These rows are never in sort order, and are used when updating the table after sorting the normalized content. The indexing of these rows is cross-referenced within the normalized values - the extra column value within the row array. Hopefully that makes sense.
The table.config.cache variable is useful when writing widgets that need access to the parsed content.
Numeric Internal count of the number of table columns in the header (v2.12)

This number is stored as a length (one-based), and takes into account any colspan and rowspan within the table head.

Note that the table.config.columns variable does not always correlate with the indexing of the headers stored within table.config.$headers because of multiple rows and column or row spans.
Array Internal list of each header's starting HTML (as text) (v2.8)

This HTML snapshot is taken using the $headers jQuery object, and done before the headerTemplate is applied and before the onRenderTemplate and onRenderHeader callbacks are executed.

This list is used by the $.tablesorter.restoreHeaders function to restore the table headers when the destroy method is executed.
Array Internal list of each header element as selected using jQuery selectors in the selectorHeaders option.

This list contains DOM elements (not jQuery objects of each table header cell like the $headers variable) and is how the original version of tablesorter stored these objects.
It is not used in the current version of tablesorter, and is only left in place for backwards compatibility with widgets written for the original tablesorter plugin.
Array Internal list of all of the table's currently set parsers (objects copied from $.tablesorter.parsers). Here is a complete list of default parsers:

parser: falsedisable parsing for this column (this also disables sorting & filtering for the column; v2.17.6).
sorter: falsedisable sort for this column.
sorter: "text"Sort alpha-numerically.
sorter: "digit"Sort numerically.
sorter: "currency"Sort by currency value (supports "£$€¤¥¢").
sorter: "image"Sort by image alt value (see imgAttr option).
sorter: "ipAddress"Sort by IP Address; Warning This parser was moved to the parser-network.js file in v2.18.0.
sorter: "url"Sort by url.
sorter: "isoDate"Sort by ISO date (YYYY-MM-DD or YYYY/MM/DD; these formats can be followed by a time).
sorter: "percent"Sort by percent.
sorter: "usLongDate"Sort by date (U.S. Standard, e.g. Jan 18, 2001 9:12 AM or 18 Jan 2001 9:12 AM (new in v2.7.4)).
sorter: "shortDate"Sort by a shortened date (see dateFormat; these formats can also be followed by a time).
sorter: "time"Sort by time (23:59 or 12:59 pm).
sorter: "metadata"Sort by the sorter value in the metadata - requires the metadata plugin.

Check out the headers option to see how to use these parsers in your table (example #1).
Or add a header class name using "sorter-" plus the parser name (example #2), this includes custom parsers (example #3).
1 2 3
jQuery Object Internal list of all extra table header cells (v2.16.2)

When the bindEvents function is used, the extra (external) header cells are added to this variable, and automatically updated with the table headers (config.$headers).

So, when writing a custom widget that clones the table header, there is no longer a need to update the header class names, it's all done automatically.
jQuery Object Internal list of all table header cells (v2.8)

The header cells are targeted using the jQuery selector from the selectorHeaders option.

Please note that the headers cells are simply an array of all header cells and should not be targeted using a column index. For example, given the following table thead markup, the header-index counts the header th cells and does not actually match the data-column index when extra rows and/or colspan or rowspan are included in any of the header cells:
<thead>
	<tr>
		<th colspan="4" data-column="0">header-index 0</th>
	</tr>
	<tr>
		<th data-column="0">header-index 1</th>
		<th data-column="1">header-index 2</th>
		<th data-column="2">header-index 3</th>
		<th data-column="3">header-index 4</th>
	</tr>
	<tr>
		<th colspan="2" data-column="0">header-index 5</th>
		<th colspan="2" data-column="2">header-index 6</th>
	</tr>
</thead>
So, in the above example, to target the header cell in the second table column (data-column index of 1), use the following code: table.config.$headers.filter('[data-column="1"]') or table.config.$headers.eq(2).

The table.config.$headers variable is useful within callback functions or when writing widgets that target the table header cells.
DOM element Internally stored DOM table element (v2.17.5)

The table.config.table variable is useful when certain callback functions only pass the config object; originally you could use config.$table[0], but this saves that small extra trouble.
jQuery Object Internally stored jQuery object of the table (v2.7.1)

The table.config.$table variable is useful within callback functions or when writing widgets that target the table.
jQuery Object Internally stored jQuery object of table non-info block tbodies (v2.7.1)

jQuery object of sortable tbodies.

Caution! These tbodies are the ones without a class name from the cssInfoBlock option, so the indexing of this jQuery object does not match the actual table tbody indexes.

The table.config.$tbodies variable is useful within callback functions or when writing widgets that target the table.
Boolean Boolean value indicating that tablesorter has been initialized on a table

This variable is not stored within the config, as the config would not be defined (an alternative method of determining if tablesorter has been initialized).

Access it as follows: $('table')[0].hasInitialized. It is true while tablesorter is active on a table, and false if tablesorter was destroyed.
Numeric This variable contains the total number of rows within the table, not including rows within info-only tbodies (v2.17.4; v2.17.5)

Access this internal value after tablesorter has initialized. It is also included as a variable in the filterEnd event so you can update an external count like this:
$('table').bind('filterInit filterEnd', function(event, data){
    // use data.filteredRows or this.config.filteredRows
    $('.filter-rows').html( data.filteredRows );
    $('.total-rows').html( data.totalRows );
});

If using the pager plugin or widget, the value returned from the filterEnd event will not be accurate, so you'll need to bind to the pagerComplete event instead:
$('table').bind('filterInit filterEnd pagerComplete', function(event, data){
    // Note: data = table.config (filterEnd event); and data = table.config.pager (pagerComplete event)
    // both objects contain data.filteredRows & data.totalRows
    $('.filter-rows').html( data.filteredRows );
    $('.total-rows').html( data.totalRows );
});
Access the widgetOptions (wo) using any of these methods:

// pure js, get the first table (zero index)
var wo = document.getElementsByTagName('table')[0].config.widgetOptions;
// or by table ID
var wo = document.getElementById('mytable').config.widgetOptions;

// using jQuery, get first table (zero index)
var wo = $('table')[0].config.widgetOptions;
// or from the jQuery data
var wo = $('#mytable').data('tablesorter').widgetOptions;
jQuery Object Only available when the filter widget is active. This variable contains all external search inputs with data-column="all", bound using the bindSearch function.

The table.config.widgetOptions.filter_$anyMatch variable contains one more more search inputs, and is dynamically updated if the bindSearch function is called; make sure to set the flag to force a new search so that the values of the altered filters is updated appropriately.
jQuery Object Only available when the filter widget is active. This variable contains all table cells within the filter row.

Use the table.config.$filters variable when access to filters is needed. Note! This variable contains the table cell and not the actual input because the filter_formatter function allows adding other types of value selectors (e.g. jQuery UI slider).
jQuery Object Only available when the filter widget is active. This variable contains all external search inputs bound using the bindSearch function.

The table.config.widgetOptions.filter_$externalFilters variable contains an array of jQuery objects pointing to all external inputs, even if the bindSearch function is used multiple times.
wo.filter_initialized Boolean Only available when the filter widget is active. This variable is true once the filter widget has initialized; it is undefined otherwise.
Numeric Only available when the filter widget is active. This variable contains the current number of filtered rows (v2.17.4; v2.17.5)

This internal value will show an accurate number of filtered rows; which means the count won't include any rows from "information-only" tbodies.

Access this internal value at any time after the filter widget has initialized, or as a shortcut it is included as a variable in the filterEnd event so you can update an external count like this:
$('table').bind('filterInit filterEnd', function(event, data){
    // use data.filteredRows or this.config.filteredRows
    $('.filter-rows').html( data.filteredRows );
    $('.total-rows').html( data.totalRows );
});

If using the pager plugin or widget, the value returned from the filterEnd event will not be accurate, so you'll need to bind to the pagerComplete event instead:
$('table').bind('filterInit filterEnd pagerComplete', function(event, data){
    // Note: data = table.config (filterEnd event); and data = table.config.pager (pagerComplete event)
    // both objects contain data.filteredRows & data.totalRows
    $('.filter-rows').html( data.filteredRows );
    $('.total-rows').html( data.totalRows );
});
jQuery Object Only available when the stickyHeaders widget (not the css3 version) is active.

The table.config.widgetOptions.$sticky variable contains a jQuery object pointing to a cloned table containing the sticky header. The table contained within this variable has a class name of "containsStickyHeaders" versus the original table with a class name of "hasStickyHeaders".

Functions

Function Description
Core Functions
This function detaches the targeted tbody from the DOM to allow faster manipulation of the tbody contents (v2.4).
Use it as follows:
$.tablesorter.processTbody( table, $(tbody), getIt );
  • table - table DOM element (or jQuery object) of table containing the tbody.
  • $(tbody) - tbody jQuery object.
  • getIt - Boolean flag (optional if false).
When calling the function, to get a tbody, set the getIt boolean parameter to true and the removed tbody is returned; setting this option to false or optionally not including it will restore the tbody.
Here is a basic example of how this function is used:
var tbodyIndex, _tbody,
	table = $('#my-table')[0],
	tbodies = table.tBodies, // use table.config.$tbodies for all tbodies EXcluding information only tbodies
for (tbodyIndex = 0; tbodyIndex < tbodies.length; tbodyIndex++) {
	// detach tbody from table
	_tbody = $.tablesorter.processTbody( table, tbodies[tbodyIndex], true );
	// do something magical to the tbody
	_tbody.addClass('unicorn');
	// restore tbody
	$.tablesorter.processTbody( table, _tbody );
}
Please note that completely detaching the tbody was found to be a much quicker method of manipulating DOM elements than just hiding the tbody; this is especially true in older browsers.
This function adds the processing (indeterminant loading icon) to specific or all header cells while processing table elements (v2.4).

Use it as follows:
$.tablesorter.isProcessing( table, toggle, $ths );
  • table - table DOM element (or jQuery object) of table.
  • toggle - Boolean flag.
  • $ths - jQuery object of targetted header cells (optional; if excluded all header cells are targetted).
When calling the function, set the toggle option to add (true) or remove (false) process indicators. Include any specific header cells within the $ths variable with which to add the process indicator. When $ths is not defined and a sort is applied, the currently sorted header cells will show process indicators.

All this function does is add or remove a class name of "tablesorter-processing" and the class name contained within the cssProcessing option.

Here is a basic example of how this function is used:
$('table').bind('sortBegin sortEnd', function(event, table){
	// this is included with the basic functionality of tablesorter
	$.tablesorter.isProcessing( this, event === 'sortBegin' );
});
Please note that currently the processing icons do not animate (see issue #158). This is due to javascript being a single-threaded, meaning it only does one task at a time, and maximizing the sorting script. So lots of processing is needed to sort & rebuild the table and thus it has no time for animation. If someone knows of a better solution, please share!
This function empties ALL of the table tbodies (v2.17.2).

Use it as follows:
$.tablesorter.clearTableBody( table );
  • table - table DOM element (or jQuery object) of table.
Please note that this function uses jQuery empty(). All data & event handlers are removed. No where within the tablesorter script or included widgets is this function used, it is left intact for backwards compatibility.
This function adds header event listeners to the targeted cells (v2.8; v2.16.2).

Use it as follows:
$.tablesorter.bindEvents( table, $headers );
  • table - table DOM element (or jQuery object) of table.
  • $headers - jQuery object of targetted cells.
This function allows you to bind the same header event listeners to external headers cells (usually clones of the original table). This includes the triggered sort event, left click (only) to sort, ignoring long clicks (> 250ms), pressing enter to trigger a sort (must have focus and a tabindex attribute) and cancelling selection of text (if the option is set).

To ensure the columns match the original table, include data-column attributes pointing to the desired column.

Here is a basic example of how this function is used:
var $table = $('table'),
	// make a copy of the table
	$clonedTable = $table.clone().addClass('clonedTable').insertAfter($table);
// remove stuff we don't need in the clone
$clonedTable.find('tfoot,tbody').remove();
// bind events to the cloned headers
$.tablesorter.bindEvents( $table, $clonedTable.find('th') );
In v2.16.2, this function now saves all extra (external) headers to the config.$extraHeaders variable which allows the plugin to automatically update the sort status.
This function restores the table headers cells with their original content (v2.8).

The original header cell content is saved, within the headerContent variable array, before the headerTemplate is applied and before the onRenderTemplate and onRenderHeader callbacks are executed.

Use it as follows:
$.tablesorter.restoreHeaders( table );
  • table - table DOM element (or jQuery object) of table.
Please note that only header cells that still contain a div with a class name of tablesorter-header-inner will have their contents restored; it assumes that the contents have already been restored.
This function completely removes tablesorter, including all widgets, associated data & event handlers from the table (v2.3.2).

Use it as follows:
$.tablesorter.destroy( table, removeClasses, callback );
  • table - table DOM element (or jQuery object) of table.
  • removeClasses - Boolean flag
  • callback - Function executed once tablesorter has been removed.
When calling the function, set the removeClasses option to true to include removing of the "tablesorter" class name, tablesorter theme name (e.g. "tablesorter-blue") and the class name applied by the tableClass option. The callback function only provides a table (DOM element only) parameter.

Here is a basic example of how this function is used:
$.tablesorter.destroy( table, true, function(table){
	alert('tablesorter has been removed! No sort for you!');
});
Please note that only header cells that still contain a div with a class name of tablesorter-header-inner will have their contents restored; it assumes that the contents have already been restored.
This function sorts the a & b parameter using a natural sort (v2.12).

Access it as follows:
$.tablesorter.sortNatural(a, b);
  • a - string.
  • b - string to compare.
Here is a basic example of how this function is used:
var myArray = [ '1a', '10a', '2a', '2b' ];
// result: ["1a", "2a", "2b", "10a"]
myArray.sort(function(a,b) { return $.tablesorter.sortNatural(a, b); });
Please note that this natural sort function only accepts strings (added v2.0.6; renamed v2.12).
This function sorts the a & b parameter using a basic sort (renamed v2.12).

Access it as follows:
$.tablesorter.sortText(a, b);
  • a - string.
  • b - string to compare.
Here is a basic example of how this function is used:
var myArray = [ '1a', '10a', '2a', '2b' ];
// result: ["10a", "1a", "2a", "2b"]
myArray.sort(function(a,b) { return $.tablesorter.sortText(a, b); });
This function replaces basic accented characters to better sorting & filtering of table contents (v2.2).

Use it as follows:
$.tablesorter.replaceAccents(string);
  • string - a string to process & replace accented characters.
Here is a basic example of how this function is used:
$.tablesorter.replaceAccents("áàâãä"); // result: "aaaaa"
This function is used when the sortLocaleCompare option is set to true. Please refer to the option and the demo for more details on the defaults values and how to add more accented characters.
This function returns a zero-based index value of the position of the value within the array, otherwise it returns -1 (Modified v2.15.6).

Use it as follows:
$.tablesorter.isValueInArray(value, array);
  • value - value to find within the array.
  • array - array (sortList) to search for the value.
Sadly, this function has limited usefulness outside of tablesorter. It is only meant to search a sortList array and determine if a column (value) is already contained within it. Here is a basic example of how this function is used:
var sortList = [ [1,0], [2,0], [0,0] ];
// result: 1
$.tablesorter.isValueInArray(2, sortList);
After v2.15.6, this function returns a zero-based index of the position of the value within the array parameter, or -1 if the value is not in the array. Previously, this function returned a boolean value of true if the value was contained within the array, or false if not.
This function allows the adding of custom parser scripts to the tablesorter core.

Access it as follows:
$.tablesorter.addParser(myParser);
  • myParser - object containing parser code.
The myParser object must contain a proper template. The template must include an id, is, format and type blocks. Please refer to the writing custom parsers demo page for more details & an example.
This function returns the named parser object.

Access it as follows:
$.tablesorter.getParserById(name);
  • name - the name (or id) of the parser.
Use this function as follows:
var parser = $.tablesorter.getParserById("currency"),
	value = parser.format('100%'); // returns 100 (number type, not a string)
This function allows the checking to see if a widget is installed (v2.17.4).

Access it as follows:
$.tablesorter.hasWidget( table, 'mywidget');
  • table - table element or jQuery object of the selected table.
  • 'mywidget' - ID of the widget to check.
This function returns a boolean value, where true means the widget is currently installed and active; and false means the widget is not installed.

Use this function as follows:
$.tablesorter.hasWidget( $('table'), 'zebra' ); // true
This function allows the adding of custom widget scripts to the tablesorter core.

Access it as follows:
$.tablesorter.addWidget(myWidget);
  • myWidget - object containing widget code.
The myWidget object must contain a proper template. The template must include an id and format blocks. The priority, options, init and remove blocks are optional. Please refer to the writing custom widgets demo page for more details & an example.
This function returns the named widget object.

Access it as follows:
$.tablesorter.getWidgetById(name);
  • name - the name (or id) of the widget.
Use this function as follows:
var widget = $.tablesorter.getWidgetById("saveSort"),
	table = $('table')[0];
// apply save sort widget to a table; but it will get removed if the refreshWidgets method
// is triggered, unless the table.config.widgets array contains this widget name/id
widget.format( table, table.config, table.config.widgetOptions );
This function applys (refreshes) all currently selected widgets on a table (v2.16.0).

Use it as follows:
$.tablesorter.applyWidget( table, init );
  • table - table DOM element (or jQuery object) of table.
  • init - optional, boolean initialization flag.
The init flag is only set to true to extend the default option values from the widget options block. If the widget(s) have already been applied to the table, just leave this parameter undefined.

This function is called when the applyWidgets method is triggered.
This function removes, then reapplies all currently selected widgets on a table (v2.4).

Use it as follows:
$.tablesorter.refreshWidgets( table, doAll, dontapply );
  • table - table DOM element (or jQuery object) of table.
  • doAll - optional, boolean flag.
  • dontapply - optional, boolean flag.
The doAll flag is set to true if all widgets contained with the global $.tablesorter.widgets array are to be removed.

This function is called when the refreshWidgets method is triggered.
This functions gets the sorter, string, empty, etc options for each column from jQuery data, metadata, header option or header class name ("sorter-false") (v2.1.16).

priority = jQuery data > meta > headers option > header class name

Use it as follows:
$.tablesorter.getData(headerCell, configHeaders, key);
  • headerCell - table DOM element (or jQuery object) of targetted header cell.
  • configHeaders - table.config.headers option for the current column.
  • key - get value for this option name, e.g. "sorter".
If the value of the "sorter" option is needed for a column, set the key to "sorter" and this function will return the set value, e.g. false, digit, currency etc.
Use this function as follows:
var column = 2,
	config = $('table')[0].config,
	headerCell = config.$headers.filter('[data-column="' + column + '"]');
// e.g. returns "false" if the header cell has the "sorter-false" class name
$.tablesorter.getData( headerCell, config.headers[column], "sorter" );
The reason there is a priority is because that is the order in which the values are searched, only the first (higher priority) value is returned.
This function converts a number string into a number type.

Use it as follows:
$.tablesorter.formatFloat(string, table);
  • string - a string possibly containing a number.
  • table - table DOM element (or jQuery object) of table.
If string is empty, not a string type, or not a number (after processing), the string itself is returned.

This function uses the usNumberFormat option to determine if either commas or decimals are removed before converting the value within the string parameter into a number type variable. This function does not use the $.tablesorter.isDigit function.

Any numbers wrapped within parentheses are converted into negative numbers; but any other symbols (e.g. currency) are not removed and will cause this function to determine the string as a non-number (e.g. "$1.25" will be returned as a string).

Use this function as follows:
// result: -2345.67 if usNumberFormat option is true
$.tablesorter.formatFloat( "(2,345.67)", table );
This function determines if a string contains a number after removing commas, periods, quotes and spaces.

Use it as follows:
$.tablesorter.isDigit(string);
  • string - a string possibly containing a number.
This function will return a boolean value of true if the string parameter contains a number after all commas, decimals, quotes and spaces are removed, and still allow plus or minus signs, or the number wrapped in parenthesis (negative values).

Use this function as follows:
// boolean value of true returned
$.tablesorter.isDigit( "(2,345.67)" );
Adds the correct data-column indexing to all rows passed to this function (v2.16).

Use it as follows:
$.tablesorter.computeColumnIndex($rows);
  • $rows - jQuery object of rows in which to add data-column indexes
Example result:
<tr>
	<td colspan="2" data-column="0">r0c0</td>
	<td data-column="2">r0c2</td>
</tr>
<tr>
	<td data-column="0">r1c0</td>
	<td data-column="1">r1c1</td>
	<td data-column="2">r1c2</td>
</tr>
This function allows adding/removing a row to the thead, to display any errors (v2.15).

This function is ONLY included within the widget-pager.js and jquery.tablesorter.pager.js files; in version 3+, I plan to add it as a selectable option in a build.

Use it as follows:
$.tablesorter.showError( table, message );
  • table - table DOM element (or jQuery object) of table (or tables).
  • message - a plain string, or string of an HTML row.
This function will add a table row to the thead, with a class name from either the pager plugin cssErrorRow option setting, or the pager widget pager_css.errorRow option (the default class name is "tablesorter-errorRow"; and styled within each theme css file).

When passing this function a message, there are three possibilities:
  1. Plain string - "table refuses to cooperate"
  2. HTML row string - '<tr><td colspan="' + table.config.columns + '">yeah, instead of showing your data... I am taking a nap</td></tr>' (the table.config.columns variable contains the number of table columns; use as needed)
  3. undefined - completely leave out a message parameter $.tablesorter.showError( table ); to remove all error rows from the table thead.
Widget Functions
This filter widget function allows binding external search filters to the table (v2.13.3; v2.15).

Access it as follows:
$.tablesorter.filter.bindSearch(table, $els, false);
  • table - table DOM element (or jQuery object) of table.
  • $els - jQuery object of all input (search) elements to bind.
  • false - boolean flag to force a new search.
The external elements ($els) will allow searching the table using "search" and "keyup" events (enter to start & escape to cancel the search), and uses the filter_liveSearch option, or delayed search.

Include a data-column="#" attribute (where # is the column number) in the search input, to specify to which column the search should apply ~ see this demo for a full example. Warning!, if no data-column attribute is added to the input, the input will be ignored.

In v2.15, use a data-column="all" to bind an external any-match search filter; but note that adding an external any-match filter using this method will not override the filter set by the filter_external option.

The third function parameter, false, is optional. When set to false it forces the inputs to update their values (same as setting the apply flag when using the setFilters function), and reapplies (forces) the current search to be applied again, even if the filter values have not changed; this allows changing the data column attribute dynamically. See the filter external inputs demo for an example.

Warning! If the third parameter is set to true the saved internal filters (config.$filters) will be replaced - not recommended!
This filter widget function allows the updating or replacing of filter select options from an external source. (v2.17.5):

Access it as follows:
$.tablesorter.filter.buildSelect( table, column, options, replace, onlyAvail );
  • table - table DOM element (or jQuery object) of table.
  • column - zero-based column index.
  • options - array of options, jQuery object of option elements, or HTML string of option elements to apply to the targetted select.
  • replace - a boolean value, which if true all options will be replaced; if false the options will be appended to the current list of options.
  • onlyAvail - an optional boolean flag, which will be ignored if the options parameter is defined or is an empty string; otherwise it is the value passed to the function which finds all table column values; if true, only the available options will be diplayed.
Use this function as follows:
// replace filter select options for the first column with 1,2,3,4
$.tablesorter.filter.buildSelect( $('table'), 0, [ 1, 2, 3, 4 ], true );

// append "Aaron" and "Fred" to the second column's filter select options. These options will remain unsorted.
$.tablesorter.filter.buildSelect( $('table'), 1, $(''), false );
Please be aware that this function will allow you to modify the select options, but as soon as the user filters any column, all of the select options will refresh and obtain options from the table column, or from the filter_selectSource function.
This filter widget function allows getting an array of the currently applied filters (v2.9; v2.15)

Access it as follows:
$.tablesorter.getFilters(table, flag);
  • table - table DOM element (or jQuery object) of table.
  • flag - boolean flag (optional; false by default), added v2.15
Use this function as follows:
// use $('table') or $('table.hasFilters') to make sure the table has a filter row
// only required if the stickyHeaders or scroller widget is being used (they duplicate the table)
$.tablesorter.getFilters( $('table') );
This function returns an array of filter values (e.g. [ '', '', '', '', '', '2?%' ]), or false if the selected table does not have a filter row. It will also return an additional parameter if an external input with data-column="all" containing the value used when matching any table column.

In v2.15, this function will also return values from any external filters (set either by the filter_external option or using the bindSearch function) - with or without an internal filter row.

If the second parameter is set to true, it forces the function to get all of the current filter values directly from the inputs. Otherwise, by default, the function returns the last search as found in this stored data $('table').data('lastSearch');.
This filter widget function allows setting of the filters; include a true boolean to actually apply the search (v2.9; v2.16):

Access it as follows:
$.tablesorter.setFilters(table, filter, apply);
  • table - table DOM element (or jQuery object) of table.
  • filter - array of filter values to apply to the table.
  • apply - boolean flag, if false (default setting), the input values are updated, but not searched for within the table.
Use this function as follows:
// update filters, but don't apply the search
$.tablesorter.setFilters( $('table'), [ '', '', '', '', '', '2?%' ] );

// update filters, AND apply the search
$.tablesorter.setFilters( $('table'), [ '', '', '', '', '', '2?%' ], true ); // this will now use the search method
This function returns true if the filters were sucessfully applied, or false if the table does not have a filter row.

As of v2.15, this function will also set values in any external filters (set either by the filter_external option or using the bindSearch function). An additional search parameter can be included to match any column, but please include an external input with data-column="all" using the bindSearch function so your users will know that a search has been applied.

Also, changed is that when a true value is passed as a third parameter, the search is forced to refresh on the table; otherwise, if the filters set in the search exactly match the previous search, it would be ignored - this was added to prevent numerous ajax calls with exactly the same search or sort parameters (when using the pager).
This resizable widget function allows resetting column width changes and clearing out the saved set widths (v2.4; v2.15)

Use it as follows:
$.tablesorter.resizableReset(table);
  • table - table DOM element (or jQuery object) of table(s).
This function is used when the user right-clicks on the table header.
Added a resize event to the table headers - used by the stickyHeaders widget, but this is a public function available to any widget (v2.10).

There is no built-in resize event for non-window elements, so when this function is active it triggers a resize event when the header cell changes size. So, if you are writing your own widget and need a header resize event, just include the jquery.tablesorter.widgets.js file, or just the extract the function from that file.

Access it as follows:
$.tablesorter.addHeaderResizeEvent(table, disable, { timer : 250 });
  • table - table DOM element (or jQuery object) of table.
  • disable - boolean flag, if false events for the targetted table are disabled.
  • timer - currently only the timer option is available for modification.
Enable these triggered events as follows:
var table = $('table')[0],
    disable = false,
    options = {
      timer : 250 // header cell size is checked every 250 milliseconds (1/4 of a second)
    };
$.tablesorter.addHeaderResizeEvent( table, disable, options );
Then use it in your custom widget as follows:
$(table).on('resize', function(event, columns){
  // columns contains an array of header cells that were resized
  // this seemed like a better idea than firing off a resize event for every
  // column when the table adjusts itself to fit within its container
  event.stopPropagation(); // optional
  // do something
  console.log( columns );
});
To disable these resize events, use this code:
// Disable resize event triggering:
var table = $('table')[0];
$.tablesorter.addHeaderResizeEvent( table, true );
This function allows saving specific table data (especially widgets) to local storage (cookie fallback for no browser support) (v2.1)

Access it as follows:
$.tablesorter.storage(table, key, value, options);
  • table - table DOM element (or jQuery object) of table.
  • key - name of the variable to save
  • value - value of the variable that is saved (for saving only); set to null if wanting to get a value with options.
  • options - storage options; see below
This function attempts to give every table a unique identifier using both the page url and table id (or index on the page if no id exists), by default. Here is a usage example and a look at what is stored within the local storage:
$.tablesorter.storage( $('#tablesorter-demo')[0], 'test', '123');
// stored as, test = : {"/tablesorter/docs/":{"tablesorter-demo":"123"}}

The saved table url & id can be overridden by setting table data attributes data-table-page (url) and data-table-group (id), as in this sample markup:
<table class="tablesorter" data-table-page="mydomain" data-table-group="financial">...</table>)
To change the default data attributes, use the options to modify them as follows:
$.tablesorter.storage( table, key, value, {
  // table id/group id
  id  : 'group1',
  // this group option sets name of the table attribute with the ID;
  // but the value within this data attribute is overridden by the above id option
  group: 'data-table-group'

  // table pages
  url : 'page1',
  // this page option sets name of the table attribute with the page/url;
  // but the value within the data attribute is overridden by the above url option
  page: 'data-table-page'
});
The priority of table ID settings is as follows:
  1. options.id setting
  2. Table data attribute (data-table-group by default) value
  3. Table id
  4. Index of the table on the page
The priority of table url (group) settings is as follows:
  1. options.url setting
  2. Table data attribute (data-table-page by default) value
  3. fixedUrl option value
  4. window.location.pathname

The fixedUrl option allows you to override the current page url (it doesn't need to be a url, just some constant value) and save data for multiple tables across a domain. The value from this option has a lower priority than the options id or group settings (see priority list above).

When using the storage utility to get a value and use custom table options, set the value parameter to null.

Lastly, this storage utility function needs the parseJSON function available in jQuery v1.4.1+.
