Hi Marcel,
I think there is an easy way to do this by replacing the tr completely.
This way you can create a new "tr" with the correct part name:
<index-page>
<collection: replace>
<data-table/>
</collection:>
</index-page>
<def tag="data-table">
<table-plus without-page-nav without-header fields="this, sum_x,
sum_y, add_x, add_y, actions">
<tr: replace>
<tr part="row">
<td><a/></td>
<td><view:sum_x/></td>
<td><view:sum_y/></td>
<td>
<form:datapoints.new ajax refocus-form>
<input:x/>
<input:y/>
<submit label="Add"/>
</form>
</td>
</tr>
</tr:>
</table-plus>
</def>
I tested this locally, so it should work ;)
Regards,
Ignacio
