title: How to properly loop three dimensional array in twig?
body: <p>I have an array setup like so; and I cant seem to loop through the values with twig:</p>
  
  <pre><code>array (size=1)
    'hash' =&gt; 
      array (size=7)
        0 =&gt; 
          array (size=4)
            'key1' =&gt; "val"
            'key2' =&gt; "val"
            'key3' =&gt; "val"
            'key4' =&gt; "val"
        1 =&gt; 
          array (size=4)
            'key1' =&gt; "val"
            'key2' =&gt; "val"
            'key3' =&gt; "val"
            'key4' =&gt; "val"
        ...
  </code></pre>
  
  <p>The template code I'm using (in its nth iteration):</p>
  
  <pre><code>  {% for i in hash %}
      {% for j in i %}
        &lt;td&gt;{{ j.key1 }}&lt;/td&gt;
        &lt;td&gt;{{ j.key2 }}&lt;/td&gt;
        &lt;td&gt;{{ j.key3 }}&lt;/td&gt;
        &lt;td&gt;{{ j.key4 }}&lt;/td&gt;
      {% endfor %}
    {% endfor %}
  </code></pre>
  
  <p>I keep getting <code>Array to string conversion</code> errors with the above twig template code.</p>
