This makes no sense. You could end up with invalid HTML and thats
what ZPT avoids.

Thats valid HTML but ugly - better you avoid empty cells or use
colspan.

Why not prepare your data as lists of lists and go like this:

<tr tal:repeat="row here/datafunction">
  <td tal:repeat="column row" tal:content="column">Sample</td>
</tr>

ready.

(You can also use lists of dicts if you want more data per
row for example background color alternation if your client
does not properly support the CSS way to do so)
