# DataTables example Ordering plug-ins (with type detection)

Although DataTables will automatically order data from a number of different data types using the built in methods, When dealing with more complex formatted data, it can be desirable to define the ordering order yourself. Using plug-in ordering functions, you have have DataTables sort data in any manner you wish.

Formatted data of a particular kind can be automatically detected and a suitable ordering plug-in assigned to it by making use of DataTables' plug-in type detection abilities. For complete information about type detection and ordering plug-ins; creating them and their requirements, please refer to the plug-in development documentation.

This example shows ordering with using an enumerated type.

A wide variety of ready made ordering plug-ins can be found on the DataTables plug-ins page.

- Javascript
- HTML
- CSS
- Ajax
- Server-side script

The Javascript shown below is used to initialise the table shown in this example:

`$.fn.dataTable.ext.type.detect.unshift( function ( d ) { return d === 'Low' || d === 'Medium' || d === 'High' ? 'salary-grade' : null; } ); $.fn.dataTable.ext.type.order['salary-grade-pre'] = function ( d ) { switch ( d ) { case 'Low': return 1; case 'Medium': return 2; case 'High': return 3; } return 0; }; $(document).ready(function() { $('#example').dataTable(); } );`

In addition to the above code, the following Javascript library files are loaded for use in this example:

- ../../media/js/jquery.js
- ../../media/js/jquery.dataTables.js

The HTML shown below is the raw HTML table element, before it has been enhanced by DataTables:

This example uses a little bit of additional CSS beyond what is loaded from the library files (below), in order to correctly display the table. The additional CSS used is shown below:

``

The following CSS library files are loaded for use in this example to provide the styling of the table:

- ../../media/css/jquery.dataTables.css

This table loads data by Ajax. The latest data that has been loaded is shown below. This data will update automatically as any additional data is loaded.

The script used to perform the server-side processing for this table is shown below. Please note that this is just an example script using PHP. Server-side processing scripts can be written in any language, using the protocol described in the DataTables documentation.
