Dynamic number of columns in Django template

I have recently tried to solve the challenge of handling a dynamic number of columns in my Django template (essentially working through a list containing lists that isnt standerdized).

I pass two things to my view:

test_array: an array that looks something like the following [[1,2,3],[1,2,3],[1,2,3]]

numbers: in this case 3 (indicating the number of attributes in the sub lists

I thought to solve this as follows:

<tbody>
   {% for t in test_array %}
      <tr>
         {% for x in numbers %}
            <td>{{ t.x }}</td>
         {% endfor %}
       </tr>
    {% endfor %}
 </tbody>

But the above returns no output. When I reference t.1, t.2 etc hardcoded this returns output.

As such, what is the best way to handle a dynamic number of columns in Django? Or, is there a more elegant way to solve the above?

Passing the length of the sublists to the the template isn't necessary.

As the list elements are also lists the inner loop could simply be reduced to this:

  {% for x in t %}
    <td>{{ x }}</td>
  {% endfor %}
