Thanks for the quick reply! I just had to add a .value
and that worked perfectly!
{% for recordId, record in entityview.rows %}
<tr>
<td>{{ record['vt_group_trainingid'].value}}</td>
<td>{{ record['vt_start_time'] is empty ? "" : record['vt_start_time'].value | date("d/m/Y") }}</td>
<td>{{ record['vt_end_time'] is empty ? "" : record['vt_end_time'].value | date("d/m/Y") }}</td>
<td><a href="#">Book this training</a></td>
</tr>
{% endfor %}
Kind regards
Sven
