                        <li ng-click="ficha(base)"><a href="javascript:void(0)"><i class="icon-barcode"></i>
                                Imprimir
                            </a></li>
                        <li ng-click="ficha(base)"><a href="javascript:void(0)"><i class="icon-share-alt"></i>

                <span>{{base.interessado}}</span>
                <span>{{base.observacoes}}</span>
            </td>
            <td>{{base.data}}</td>
            <td>{{base.assunto}}</td>
        </tr>
    </tbody>
</table>

Used ng-repeat simple.

ng-repeat table dynamic

Answer 1

You can use a container to loop the items and then repeat the first tr and add a second tr that has the colspan. This may not be in the same version of angular but the general idea is like so

<ng-container *ngFor="let base of list; let i = index">
  <tr>
     <!--- Row of base.* //-->
  </tr>
  <tr>
     <td colspan="4">Observations</td>
  </tr>
</ng-container>
