Preamble

The following example shows how a callback function can be used to format a particular row at draw time. For each row that is generated for display, the fnRowCallback() function is called. It is passed the row node which can then be modified and returned. In this case a trivial example of making the 'grade' column bold if the grade is 'A' is shown (note that this could also be performed using the fnRender() function, but this is just for example).

Live example

Initialisation code

$(document).ready(function() {
	$('#example').dataTable( {
		"fnRowCallback": function( nRow, aData, iDisplayIndex ) {
			/* Append the grade to the default row class name */
			if ( aData[4] == "A" )
			{
				$('td:eq(4)', nRow).html( '<b>A</b>' );
			}
			return nRow;
		},
		"aoColumnDefs": [ {
				"sClass": "center",
				"aTargets": [ -1, -2 ]
		} ]
	} );
} );
