Leverage ngRepeat alongside a conditional directive to enhance functionality

I'm currently learning AngularJS for a project and I have a model that includes elements of different types. I want to display these elements in a table similar to the example below:

<table>
  <tr><td>nameA</td><td>...</td><td>...</td></tr>         <!-- elements of type A -->
  <tr><td>nameB</td><td colspan="2">...data...</td></tr>  <!-- elements of type B -->
  <tr><td>nameC</td><td>...</td><td>...</td></tr>         <!-- elements of type A -->
</table>

I need to figure out how to achieve this using AngularJS. So far, I've tried the following:

<table>
  <tr ng-repeat="elem in data.elements | orderBy:'name'">
    <td>{{ elem.name }}</td><td>...</td><td>...</td>
  </tr>
</table>

Unfortunately, all the rows look the same. I'm unsure how to create a conditional directive based on elem.type to use different templates for each row. Ideally, something like this:

<table>
  <tr ng-repeat="elem in data.elements | orderBy:'name'">
    <pseudo-tag ng-if="elem.type == 'typeA'">
      <td>{{ elem.name }}</td><td>...</td><td>...</td>
    </pseudo-tag>
    <pseudo-tag ng-if="elem.type == 'typeB'">
      <td>{{ elem.name }}</td><td colspan="2">...data...</td>
    </pseudo-tag>
  </tr>
</table>

I would greatly appreciate any guidance on the proper AngularJS approach to solving this problem.

There is no need to use a pseudo-tag when you can simply apply the ng-if directive directly to the td element. This code snippet demonstrates how this can be achieved:

<table>
  <tr ng-repeat="element in vm.list | orderBy:'name'">
    <td ng-if="element.type === 'typeA' || element.type === 'typeB'">{{ element.name }}</td>
    <td ng-if="element.type === 'typeB'" colspan="2">...data...</td>
    <td ng-if="element.type === 'typeA'">...</td>
    ...
  </tr>
</table>
