I'm not sure exactly what you want to print--do you want to print
the name of the item found in the folder? The title? The contents?

<dtml-in "objectValues(['Folder'])">
  <tr>
    <td><dtml-var title_or_id></td>
  </tr>
</dtml-in>

This will print the title, or failing that, the ID.

The Zope book is an excellent reference for questions like this.
