[Zope] tal:repeat question

[Kevin Carlson]

After all the recent discussion around TAL, I've decided to finally take 
the time to get to know it better.  So far, I must admit it's a lot 
easier than I thought it was from the looks of it and I have been able 
to convert almost an entire small site to TAL in an evening.  However, 
one small puzzle remains for now.

I wish to display a group of pictures in a 3 by 3 table.  I'm currently 
doing that with the following dtml.  Can anyone suggest how to do this 
in TAL?  I've searched the archives and haven't been able to turn up 
anything that helps...

   <table>
   <dtml-in expr="objectValues('Image')" size=9 start=query_start>
   <dtml-if expr="_['sequence-index'] % 3 == 0">
      <dtml-if expr="_['sequence-index'] > 0">
         </tr>
      </dtml-if>
    <tr width="33%">
   </dtml-if>
    <td class="photo_title"><dtml-var sequence-item></td>
   </dtml-in>
   </table>

I know one way would be to call a python script that populated a list of 
lists containing the necessary objectValues, but I am curious as if that 
is the most efficient and/or only way.

Thanks,

Kevin
