[Structures_DataGrid] Additional headers

Hi all, I'd like to render a table with headers above the "main" header, that is, the header that handles ordering. These additional headers are used in order to group headers, for example: <table width="50%" cellspacing="1" cellpadding="4" class="datagrid"> <!-- additional header --> <tr bgcolor="#3399FF"> <th colspan="2">Person info</th> <th colspan="2">Actions</th> </tr> <!-- default header --> <tr bgcolor="#3399FF"> <th><a href="/example.php?orderBy=first_name&amp;direction=ASC">Name</a></th> <th><a href="/example.php?orderBy=age&amp;direction=ASC">Age</a></th> <th>Edit</th> <th>Delete</th> </tr> </table> I haven't seen a way using the package methods, and I'm thinking of managing this additional headers creating another renderer based on (inheriting) the HTMLTable renderer, which would handle this. E.g. $dg->renderer->setSuperheaders (array (

                           0 => array(
                                   0 => array(
                                           'cols' => 2,
                                           'label' => 'Person info'),
                                    1 => array(
                                           'cols' => 2,
                                           'label' => 'Actions')
                                             )
                           ));

Any work done on this so far? Advice? I'd hate to reinvent this wheel.... :-) King regards, -- Daniel
