AngularJS: Utilizing nested ng-repeats for dynamic data rendering

Currently, I am utilizing the ng-repeat directive in conjunction with the ng-repeat-start/ng-repeat-end options. Within the main loop, there is an additional inner ng-repeat. However, the problem lies in the fact that the outer ng-repeat-start declaration serves solely as a looping mechanism and I do not actually need to repeat the HTML element on which it is declared. Below is an example:

<tbody>
    <tr ng-repeat-start="anArray in arrayOfArrays">  <!-- HOW TO REMOVE THIS EMPTY <tr>? -->

    </tr>

    <tr ng-repeat="item in anArray ">
        <td>{{item .name}}</span></td>
        <td>{{item .surname}}</td>
    </tr>

    <tr ng-repeat-end>
        <td>
            <span>Total</span>
        </td>
    </tr>
</tbody>

I am seeking a way to remove the <tr> element while still maintaining the loop declaration.

I attempted to declare both loops (outer and inner) within the same <tr> element, but this approach did not prove successful:

<tr ng-repeat-start="anArray in arrayOfArrays" ng-repeat="item in anArray ">          
  </tr>

If you need to replicate all elements in the outer loop, you can achieve this by using the <tbody> tag for repetition. See code snippet below:

<tbody ng-repeat="anArray in arrayOfArrays">
    <tr ng-repeat="item in anArray ">
        <td>{{item .name}}</span></td>
        <td>{{item .surname}}</td>
    </tr>
    <tr>
        <td>
            <span>Total</span>
        </td>
    </tr>
</tbody>

If your goal is to duplicate only the inner loop and display the total once, consider splitting your table into two sections as shown below:

<tbody ng-repeat="anArray in arrayOfArrays">
    <tr ng-repeat="item in anArray ">
        <td>{{item .name}}</span></td>
        <td>{{item .surname}}</td>
    </tr>
</tbody>
<tfooter>
      <tr>
        <td>
            <span>Total</span>
        </td>
      </tr>
</tfooter>
