OK, then why not do something like:

<dtml-in "objectValues('my Object')>
  <dtml-if sequence-odd>
    <dtml-if sequence-last>
      <tr>
      <td><dtml-var expr="getProperty('firstProp')"></td>
      <td>&nbsp;</td>
      </tr><tr>
      <td><dtml-var expr="getProperty('secondProp')"></td>
      <td>&nbsp;</td>
      </tr>
    <dtml-else>
      <dtml-set save_prop_one="getProperty('firstProp')">
      <dtml-set save_prop_two="getProperty('secondProp')">
    </dtml-if>
  <dtml-else>
    <tr>
    <td><dtml-var prop_one></td>
    <td><dtml-var expr="getProperty('firstProp')"></td>
    </tr><tr>
    <td><dtml-var prop_two></td>
    <td><dtml-var expr="getProperty('secondProp')"></td>
    </tr>
  </dtml-if>
</dtml-in>
