More than one year later but found a workaround, at least for two levels (fathers->sons).
Just repeat tbody
‘s:
<table>
<tbody ng-repeat="row in rows">
<tr>
<th>{{row.name}}</th>
</tr>
<tr ng-repeat="sub in row.subrows">
<td>{{sub.name}}</td>
</tr>
</tbody>
</table>
As far as I know all browsers support multiple tbody
elements inside a table.
