A tiny & dead-simple jQuery plugin for sortable tables. Here's a basic demo.

Maintainers Wanted

I don't use this library much anymore and don't have time to maintain it solo.

If you are interested in helping me maintain this library, please let me know! Read more here »

Your help would be greatly appreciated!

Install

Just add jQuery & the tablesort plugin to your page:

<script src="http://code.jquery.com/jquery-latest.min.js"></script>
<script src="jquery.tablesort.js"></script>

(The plugin is also compatible with Zepto.js).

It's also available via npm

npm install jquery-tablesort

and bower

bower install jquery-tablesort

Basic use

Call the appropriate method on the table you want to make sortable:

$('table').tablesort();

The table will be sorted when the column headers are clicked.

To prevent a column from being sortable, just add the no-sort class:

<th class="no-sort">Photo</th>

Your table should follow this general format:

Note: If you have access to the table markup, it's better to wrap your table rows in <thead> and <tbody> elements (see below), resulting in a slightly faster sort.

If you can't use <thead>, the plugin will fall back by sorting all <tr> rows that contain a <td> element using jQuery's .has() method (ie, the header row, containing <th> elements, will remain at the top where it belongs).

<table>
	<thead>
		<tr>
			<th></th>
			...
		</tr>
	</thead>
	<tbody>
		<tr>
			<td></td>
			...
		</tr>
	</tbody>
</table>

If you want some imageless arrows to indicate the sort, just add this to your CSS:

th.sorted.ascending:after {
	content: "  \2191";
}

th.sorted.descending:after {
	content: " \2193";
}

How cells are sorted

At the moment cells are naively sorted using string comparison. By default, the <td>'s text is used, but you can easily override that by adding a data-sort-value attribute to the cell. For example to sort by a date while keeping the cell contents human-friendly, just add the timestamp as the data-sort-value:

<td data-sort-value="1331110651437">March 7, 2012</td>

This allows you to sort your cells using your own criteria without having to write a custom sort function. It also keeps the plugin lightweight by not having to guess & parse dates.

Defining custom sort functions

If you have special requirements (or don't want to clutter your markup like the above example) you can easily hook in your own function that determines the sort value for a given cell.

Custom sort functions are attached to <th> elements using data() and are used to determine the sort value for all cells in that column:

// Sort by dates in YYYY-MM-DD format
$('thead th.date').data('sortBy', function(th, td, tablesort) {
	return new Date(td.text());
});

// Sort hex values, ie: "FF0066":
$('thead th.hex').data('sortBy', function(th, td, tablesort) {
	return parseInt(td.text(), 16);
});

// Sort by an arbitrary object, ie: a Backbone model:
$('thead th.personID').data('sortBy', function(th, td, tablesort) {
	return App.People.get(td.text());
});

Sort functions are passed three parameters:

the <th> being sorted on
the <td> for which the current sort value is required
the tablesort instance

Custom comparison functions

If you need to implement more advanced sorting logic, you can specify a comparison function with the compare setting. The function works the same way as the compareFunction accepted by Array.prototype.sort():

function compare(a, b) {
  if (a < b) {
    return -1;		// `a` is less than `b` by some ordering criterion
  }
  if (a > b) {
    return 1;			// `a` is greater than `b` by the ordering criterion
  }

  return 0;				// `a` is equal to `b`
}

Events

The following events are triggered on the <table> element being sorted, 'tablesort:start' and 'tablesort:complete'. The event and tablesort instance are passed as parameters:

$('table').on('tablesort:start', function(event, tablesort) {
	console.log("Starting the sort...");
});

$('table').on('tablesort:complete', function(event, tablesort) {
	console.log("Sort finished!");
});

tablesort instances

A table's tablesort instance can be retrieved by querying the data object:

$('table').tablesort(); 												// Make the table sortable.
var tablesort = $('table').data('tablesort'); 	// Get a reference to it's tablesort instance

Properties:

tablesort.$table 			// The <table> being sorted.
tablesort.$th					// The <th> currently sorted by (null if unsorted).
tablesort.index				// The column index of tablesort.$th (or null).
tablesort.direction		// The direction of the current sort, either 'asc' or 'desc' (or null if unsorted).
tablesort.settings		// Settings for this instance (see below).

Methods:

// Sorts by the specified column and, optionally, direction ('asc' or 'desc').
// If direction is omitted, the reverse of the current direction is used.
tablesort.sort(th, direction);

tablesort.destroy();

Default Sorting

It's possible to apply a default sort on page load using the .sort() method described above. Simply grab the tablesort instance and call .sort(), padding in the <th> element you want to sort by.

Assuming your markup is <table class="sortable"> and the column to sort by default is <th class="default-sort"> you would write:

$(function() {
    $('table.sortable').tablesort().data('tablesort').sort($("th.default-sort"));
});

Settings

Here are the supported options and their default values:

$.tablesort.defaults = {
	debug: $.tablesort.DEBUG,		// Outputs some basic debug info when true.
	asc: 'sorted ascending',		// CSS classes added to `<th>` elements on sort.
	desc: 'sorted descending',
	compare: function(a, b) {		// Function used to compare values when sorting.
		if (a > b) {
			return 1;
		} else if (a < b) {
			return -1;
		} else {
			return 0;
		}
	}
};

You can also change the global debug value which overrides the instance's settings:

$.tablesort.DEBUG = false;
