This is ALREADY possible and quiet EASY, there is no need to overengineer
things. The purpose of the dataview is to repeat things not create the whole
table.

IE:

<table>
<tr><td colspan="2"><span wicket:id="title"/></td></tr>
<tr><td colspan="2"><span wicket:id="subtitle"/></td></tr>
<tr wicket:id="dataview1">
        <td><span wicket:id="col1"/></td><td><span wicket:id="col2"/></td>
</tr>
<tr><td colspan="3"><span wicket:id="subtitle2"/></td></tr>
<tr wicket:id="dataview2">
        <td><span wicket:id="col1"/></td><td><span wicket:id="col2"/></td>
</tr>
<tr><td colspan="2"><span wicket:id="footer"/></td></tr>
</table>
