This question has been partly addressed here: Angular.js ng-repeat across multiple tr's
However that is just a work-around really, it doesn't actually address the core issue, which is: how can one use ng-repeat across multiple elements without a wrapper?
For example, jquery.accordion requires you to repeat an h3 and div element, how could one do this with ng-repeat?
We now have a proper support for this, please see:
with this change you can now do:
<table>
<tr ng-repeat-start="item in list">
<td>I get repeated</td>
</tr>
<tr ng-repeat-end>
<td>I also get repeated</td>
</tr>
</table>
