Although DataTables doesn't have row grouping built-in (picking one of the many methods available would overly limit the DataTables core), it is most certainly possible to give the look and feel of row grouping.
In the example below the 'group' is the office location, which is based on the information in the third column (which is set to hidden). The grouping indicator
is added by the drawCallback
function, which will parse through the rows which are displayed, and enter a grouping TR element where a new group is found. A click event handler is
added for the grouping rows to allow the grouping order to be restored as well as ordering by any other column.
Important note: DataTables now has a RowGroup extension that provides a formal API for the abilities in
this demo and extends upon them in a number of significant and useful ways. This example is retained as a useful demonstration of how the drawCallback option can be used, but for
new sites that make use of row grouping, it is suggested that you use the new RowGroup extension.

The Javascript shown below is used to initialise the table shown in this example:
$(document).ready(function() {
var table = $('#example').DataTable({
"columnDefs": [
{ "visible": false, "targets": 2 }
],
"order": [[ 2, 'asc' ]],
"displayLength": 25,
"drawCallback": function ( settings ) {
var api = this.api();
var rows = api.rows( {page:'current'} ).nodes();
var last=null;
api.column(2, {page:'current'} ).data().each( function ( group, i ) {
if ( last !== group ) {
$(rows).eq( i ).before(
'<tr class="group"><td colspan="5">'+group+'</td></tr>'
);
last = group;
}
} );
}
} );
// Order by the grouping
$('#example tbody').on( 'click', 'tr.group', function () {
var currentOrder = table.order()[0];
if ( currentOrder[0] === 2 && currentOrder[1] === 'asc' ) {
table.order( [ 2, 'desc' ] ).draw();
}
else {
table.order( [ 2, 'asc' ] ).draw();
}
} );
} );
In addition to the above code, the following Javascript library files are loaded for use in this example:
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:
tr.group,
tr.group:hover {
background-color: #ddd !important;
}
The following CSS library files are loaded for use in this example to provide the styling of the table:
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.
