Is there a nicer way to do this with UI_Table

Dashboard

I was going to post the same thing after playing around with it! Quick question just for curiosity - is there any reason to have the "track by $index" in the table row tag? This seems to also work:

<table id="table" border="1">
 <caption>Caption</caption>
 <tr>
 <th></th>    
 <th>Period 1</th> 
 <th>Period 2</th>
 <th>Period 3</th>
 <th>Period 4</th>
 <th>Period 5</th>
 <th>Period 6</th>
 </tr>
 <tbody>
 <tr ng-repeat="row in msg.payload">
 <td ng-repeat="item in row track by $index" >{{item}}</td>
 </tr>
 </tbody>
</table>
