Not sure what you mean, maybe you want something like this:

<table tal:define="items python: 1000;
                    cols python: 12;
                    remainder python: items % cols;
                    rows python: items / cols;
                    rows python: test(remainder, rows + 1, rows);">
   <tr tal:repeat="row python: range(rows);">
     <td tal:define="start python: cols * row;
                     end python: start + cols;"
         tal:repeat="item python: range(start, end);"
         tal:content="python: test(item <= items, item, 'x');"/>
   </tr>
</table>

Yes, see the ZPT help in the ZMI or the Zope book.
