Found the workaround!

I'm trying to get the fieldgroup_table module to work with Drupal-5.2 and CCK-1.6 but I'm not having any luck.

From my limited PHP skills it looks like the '#children' values aren't getting defined when fieldgroup_table.module builds the rows for the table.

Here's what I see in the output:

<table>
 <thead><tr><th>Date</th><th>Billable hours</th><th>Description</th> </tr></thead>
<tbody>
 <tr class="odd"><td 0="field_date" 1="0"></td><td 0="field_billable_hours" 1="0"></td><td 0="field_description" 1="0"></td> </tr>
</tbody></table>

Any suggestions? I'm so close and yet so far...
