# Initialisation code

    var oTable;

    /* Formating function for row details */
    function fnFormatDetails ( nTr )
    {
    	var aData = oTable.fnGetData( nTr );
    	var sOut = '<table cellpadding="5" cellspacing="0" border="0" style="padding-left:50px;">';
    	sOut += '<tr><td>Rendering engine:</td><td>'+aData[2]+' '+aData[5]+'</td></tr>';
    	sOut += '<tr><td>Link to source:</td><td>Could provide a link here</td></tr>';
    	sOut += '<tr><td>Extra info:</td><td>And any further details here (images etc)</td></tr>';
    	sOut += '</table>';

    	return sOut;
    }

    $(document).ready(function() {
    	oTable = $('#example').dataTable( {
    		"bProcessing": true,
    		"bServerSide": true,
    		"sAjaxSource": "scripts/details_col.php",
    		"aoColumns": [
    			{ "sClass": "center", "bSortable": false },
    			null,
    			null,
    			null,
    			{ "sClass": "center" },
    			{ "sClass": "center" }
    		],
    		"aaSorting": [[1, 'asc']]
    	} );

    	$('#example tbody td img').live( 'click', function () {
    		var nTr = this.parentNode.parentNode;
    		if ( this.src.match('details_close') )
    		{
    			/* This row is already open - close it */
    			this.src = "../examples_support/details_open.png";
    			oTable.fnClose( nTr );
    		}
    		else
    		{
    			/* Open this row */
    			this.src = "../examples_support/details_close.png";
    			oTable.fnOpen( nTr, fnFormatDetails(nTr), 'details' );
    		}
    	} );
    } );

# Server response

The code below shows the latest JSON data that has been returned from the server in response to the Ajax request made by DataTables. This will update as further requests are made.

# Other examples

## Basic initialisation

- Zero configuration
- Feature enablement
- Sorting data
- Multi-column sorting
- Multiple tables
- Hidden columns
- Complex headers - grouping with colspan
- DOM positioning
- State saving
- Alternative pagination styles
- Scrolling:
  Horizontal / Vertical / Both / Themed / Infinite
- Change language information (internationalisation)
- ThemeRoller themes (Smoothness)

## Advanced initialisation

- Events:
  Live events / Pre-init / Post-init with fnGetNodes
- Column rendering
- Sorting without HTML tags
- Multiple table controls (sDom)
- Defining length menu options
- Complex headers and hidden columns
- Custom toolbar (element) around table
- Row highlighting with CSS
- Row grouping
- Row callback
- Footer callback
- Control sorting direction of columns
- Change language information from a file (internationalisation)

## API

- Dynamically add a new row
- Individual column filtering (using "input" elements)
- Individual column filtering (using "select" elements)
- Highlight rows and columns
- Show and hide details about a particular record
- User selectable rows (multiple rows)
- User selectable rows (single row) and delete rows
- Editable rows (with jEditable)
- Submit form with elements in table
- Index column (static number column)
- Show and hide columns dynamically
- API function use in initialisation object (callback)
- DataTables scrolling and tabs
- Regular expression filtering

## Data sources

- DOM
- Javascript array
- Ajax source
- Server side processing

## Server-side processing

- Obtain server-side data
- Add extra HTTP variables
- Use HTTP POST
- Automatic addition of IDs and classes to rows
- Reading table data from objects
- Show and hide details about a particular record
- User selectable rows (multiple rows)
- JSONP for a cross domain data source
- jEditable integration with DataTables
- Deferred loading of Ajax data
- Custom column ordering (in callback data)
- Pipelining data (reduce Ajax calls for paging)

## Ajax data source

- Ajax sourced data (array of arrays)
- Ajax sourced data (array of objects)
- Deferred DOM creation for extra speed
- Empty data source columns
- Use a data source other than aaData (the default)
- Read column data from sub-arrays
- Read column data from deeply nested properties

## Plug-ins

- Add custom API functions
- Sorting and automatic type detection
- Sorting without automatic type detection
- Custom pagination controls
- Range filtering / custom filtering
- Live DOM sorting
- Automatic HTML type detection
