title: angularjs: ng-repeat-start and ng-repeat-end with inner ng-repeat
body: <p>Hi I have a simple use case for ng-repeat-start and end and is working just fine, the problem appears when I want to add an inner ng-repeat.
  Here is the my code</p>
  
  <pre><code>&lt;tr ng-repeat-start="obj in rows" &gt;
    &lt;td ng-repeat="e in obj.row"&gt;{{e}}&lt;/td&gt;
  &lt;/tr&gt;
  &lt;tr ng-repeat-end&gt;
    &lt;td colspan="4"&gt;{{obj.description}}&lt;/td&gt;
  &lt;tr&gt;
  </code></pre>
  
  <p>The inner ng-repeat into td element is not working, I'm seeing the ngRepeat comment when I inspect the html source code, but the td elements are not being created.</p>
  
  <pre><code>&lt;!-- ngRepeat: e in obj.row --&gt;
  </code></pre>
  
  <p>My ugly workaround (given that I know the size of that vector) is:</p>
  
  <pre><code>&lt;tr ng-repeat-start="obj in rows" &gt;
    &lt;td&gt;{{obj.row[0]}}&lt;/td&gt;
    &lt;td&gt;{{obj.row[1]}}&lt;/td&gt;
    &lt;td&gt;{{obj.row[2]}}&lt;/td&gt;
    &lt;td&gt;{{obj.row[3]}}&lt;/td&gt;
  &lt;/tr&gt;
  &lt;tr ng-repeat-end&gt;
    &lt;td colspan="4"&gt;{{obj.description}}&lt;/td&gt;
  &lt;tr&gt;
  </code></pre>
