thank you hans. it does not work, but it was the right input for me to find the solution.

this is testet:


<dtml-let ov="objectValues('my Object')"
               lv="_.len(ov)"
>
<dtml-in "_.range(0, lv, 2)">
<dtml-let i1=sequence-item>
<tr>
<td><dtml-var "ov[i1].getProperty('firstProp')"></td>
<td><dtml-var "ov[i1+1].getProperty('firstProp')"></td>
</tr>
<tr>
<td><dtml-var "ov[i1].getProperty('secondProp')"></td>
<td><dtml-var "ov[i2].getProperty('secondProp')"></td>
</tr>
</dtml-let i1>
</dtml-in>
</dtml-let ov>
