				FixedColumns example - row grouping using the fixed column
			</div>
			
			<h1>Preamble</h1>
			<p>This example shows how it is possible to manipulate the DOM of the fixed column to create the effect of row grouping in the table (or more generally any manipulation you wish to make). When ordered by the first column it is possible to see the grouping in full effect - if you then change the ordering to one of the other columns the grouping is dynamically changed to combine like cells. It would be readily possible to extend this example to use two fixed columns and only 'group' rows in one of the columns, potentially achieving quite a powerful effect.</p>
