The example code you provided will create a <tr> on the first iteration of
the loop and </tr> tag every 4th iteration of the loop. This cycle will
continue resulting in a table with 4 columns of data. Example:
results = [ 1, 2, 3, 4, 5, 6, 7, 8 ]
<table>
<tr>
<td>1</td>
<td>2</td>
<td>3</td>
<td>4</td>
</tr>
<tr>
<td>5</td>
<td>6</td>
<td>7</td>
<td>8</td>
</tr></table>
If you have 2 lists, render them from your view like return render(request,
'polls/detail.html', {'list1': list1, 'list2': list2})
In your template create an 8 column table:
<table>
{% for r in list1 %}
{% cycle '<tr>' '' '' '' '' '' '' ''%}
<td>{{r}}</td>
{% cycle '' '' '' '' '' '' '' '</tr>' %}
{% endfor %}
{% for r in list2 %}
{% cycle '<tr>' '' '' '' '' '' '' ''%}
<td>{{r}}</td>
{% cycle '' '' '' '' '' '' '' '</tr>' %}
{% endfor %}
</table>
Hope this helps
