How to read list in django template - django

Question

Could someone shed a light to help me to solve this nested list problem in Django template.
I come across a list as such
[['Summary 1 CODE018'], [['Directory/File Name', 'Result']], [[['dir/var1/file1.txt', 'pass'], ['dir/var2/file2.txt', 'pass'], ['dir/var1/file3', 'pass']]], [[['null']]]]
How do I loop the above list so that I can get a table such as the first index is the table title, index1 is the table title and the rest (except when is it null) is the table body? Please take note that the last item could be [[['null']]] or [[['null', 'Info on directory CODEA18']]] which should be skip when null is detected.
Expected table:
Directory/File Name Result
dir/var1/file1.txt pass
dir/var2/file2.txt pass
dir/var3/file3.txt pass
My faulty code as below
<table id="myTable">
{% for list in summary %}
<tr>
<td> {{ list.0 }} </td>
<tbody>
<td> {{ list.0.0 }} </td>
<td> {{ list.0.0.0 }} </td>
</tbody>
</tr>
</table>

Answer 1

You list have 4 items. In that 2nd is Table heading and 3rd is table row.
We need to run 2 loops, one for thead and one for tbody
<table border>
<thead>
<tr>
{% for i in a[1][0] %}
<th>{{i}}</th>
{% endfor %}
</tr>
</thead>
<tbody>
{% for i in a[2][0] %}
<tr>
{% for j in i%}
<td>{{j}}</td>
{% endfor %}
</tr>
{% endfor %}
</tbody>
</table>
