• New: Accessing the parent Loop.

  The special loop variable always points to the innermost loop. If it’s desired to have access to an outer loop it’s possible to alias it:

  <table>
  {% for row in table %}
    <tr>
    {% set rowloop = loop %}
    {% for cell in row %}
      <td id="cell-{{ rowloop.index }}-{{ loop.index }}">{{ cell }}</td>
    {% endfor %}
    </tr>
  {% endfor %}
  </table>
