Example:

           <table>
             <tr wicket:id="rows">
               <td wicket:id="cells">
                 <span wicket:id="cell"> </span>
               </td>
             </tr>
           </table>
 

Though this example is about a HTML table, DataGridView is not at all limited to HTML tables. Any kind of grid can be rendered using DataGridView.

And the related Java code:

 
 ICellPopulator[] columns = new ICellPopulator[2];
 
 columns[0] = new PropertyPopulator("firstName");
 columns[1] = new PropertyPopulator("lastName");
 
 add(new DataGridView("rows", columns, new UserProvider()));
