Twig dividing data into tables - php

Question

I am working on a webapplication but ive ran into a hiccup, I have gathered data from my database and displayed the records into a datatable, my problem is that I can not just have one table the client wants me to divide the table into multiple based on what interger is in a column(omloopNummer).
The best ive gotten so far is with the following code it wil split the table up into lets say 4 tables if the interger in the database wil go 1,2,3,4 but it wil only show 1 record in each table while it should be more.
If there is any other simple solution to this instead of using twig I would be happy to try it.
<div id="index" class="table-responsive">
{% set i = 1 %}
{% for duel in duels %}
{% if duel.omloopNummer == i %}
{% set i = i + 1 %}
<table id="" class="table display-" style="width: 90%; margin-top: 30px">
<thead>
<tr>
<th>Omloop</th>
<th>Team 1</th>
<th>vs</th>
<th>Team 2</th>
<th>Acties</th>
</tr>
</thead>
<tbody>
<tr>
<td>{{ duel.omloopNummer }}</td>
<td>{{ duel.team1 }}</td>
<td>vs</td>
<td>{{ duel.team2 }}</td>
<td>{{ include('duel/_delete_form.html.twig') }}</td>
</tr>
</tbody>
</table>
{% endif %}
{% endfor %}

You could use PHP to group Duels by omloopNummer in the controller before passing to twig.
$duels = $duelRepository->findAll();
$sorted = [];
foreach($duels as $duel){
$sorted[$duel->getOmloopNummer()][] = $duel;
}
return $this->render('template.html.twig', [
'duel_groups' => $sorted,
]);
Then in twig, loop through the sorted array building a table for each non-empty group and inside each tbody loop through the group.
{% for group in duel_groups %}
...
{% if group is not empty %}
<table>
...
<tbody>
{% for duel in group %}
<tr>...</tr>
{% endfor %}
</tbody>
</table>
{% endif %}
...
{% endfor %}
