title: nested ng-repeat doesn't work
body: <p>I am using <a href="https://github.com/esvit/ng-table/" rel="nofollow">ng-table</a> to put an array structure into a table the following way :</p>
  
  <pre><code>&lt;table ng-table="tableParams" class="table" ng-controller="VenueListCtrl"&gt;
    &lt;tbody&gt;
      &lt;tr ng-repeat="entry in venues"&gt;
        &lt;div ng-repeat="(key, val) in entry"&gt;
          &lt;td data-title="key"&gt;
            {{val}}
          &lt;/td&gt;
        &lt;/div&gt;
      &lt;/tr&gt;
    &lt;/tbody&gt;
  &lt;/table&gt;
  </code></pre>
  
  <p>Consider venues to be :</p>
  
  <pre><code>[{"id":"C001","name":"Bobo"},{"id":"C002","name":"Shobo"},{"id":"C003","name":"Soho"}]
  </code></pre>
  
  <p>The first <code>ng-repeat</code> works okay as I can see the 3 rows in the table. The second <code>ng-repeat</code> doesn't seem to work.</p>
  
  <p>What am I doing wrong ?</p>
