I think the spaces around the '=' in the <al-for ... expr = "...">
tags are causing the parser regexes to not recognise the tags.  Things
which are not recognised by the regex are treated as plain text.

Try changing the template to this:

        <table>
          <al-for iter="f" expr="flist">
            <tr>
              <al-for iter="f2" expr="filenames(f)">
                <td><al-value expr="f2"></td>
              </al-for>
            </tr>
          </al-for>
        </table>
