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 t

    We now have a proper support for this, please see:

    AngularJs Commmit

    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>

    To answer Andre's question above on more than 2 levels of ng-repeat in a table, you can use multiple ng-repeat-start to accomplish this.

    <tr ng-repeat-start="items in list">
   <td>{{items.title}}</td>
</tr>
<tr ng-repeat-start="item in items">
   <td>{{item.subtitle}}</td>
</tr>
<tr ng-repeat-end ng-repeat="value in item.values">
   <td>{{value.col1}}</td>
   <td>{{value.col2}}</td>
</tr>
<tr ng-repeat-end></tr>

    Here is a plunker example

    UPDATE: This answer is outdated. Please see @IgorMinar answer and use standard ng-repeat-start and ng-repeat-end directives.

    There are two options:

    First option is to create directive that will render several tags and replace source tag (jsfiddle)

    <div multi ></div>

angular.module('components').directive('multi', function ($compile) {
return {
    restrict: 'A',
    scope : {
       first : '=',
       last : '=',
    },        
    terminal:true,

    link: function (scope, element, attrs) {
       var tmpl = '', arr = [0,1,2,3]

       // this is instead of your repeater
       for (var i in arr) {
          tmpl +='<div>another div</div>'
       }

       var newElement = angular.element(tmpl);
       $compile(newElement)(scope);
       element.replaceWith(newElement); 
    }
})

    Second option is to use updated source code of angular that enables comment style ngRepeat directive (plnkr)

    <body ng-controller="MainCtrl">
 <div ng-init="arr=[0,1,2]" ></div>
   <!-- directive: ng-repeat i in arr -->
     <div>{{i}}</div>
     <div>{{ 'foo' }}</div>  
   <!-- /ng-repeat -->

   {{ arr }}

  <div ng-click="arr.push(arr.length)">add</div>
</body>
