ng-repeat and collapse table - angularjs

Question

I am trying to display information inside a table using a button to show and hide the data in each row using the row's id, but since I have 2 ng-repeat, the first loop is completed before the second and therefore all the data is displayed in the same row : here is my code :
<div class="table-responsive">
<table class="table table-bordered table-hover table-striped">
<thead>
<tr>
<th></th>
<th>Projet</th>
<th>Responsable Apitech</th>
<th>Temps Passé</th>
</tr>
</thead>
<tbody>
<tr ng-repeat-start="p in projetsListe" >
<td>
<button class="btn btn-xs" ng-click="expanded = !expanded" expand data-toggle="collapse" id="{{p.IdProjet}}" data-target=".{{p.IdProjet}}">
<span ng-bind="expanded ? '-' : '+'"></span>
</button>
</td>
<td>{{p.NomProjet}}</td>
<td>{{p.ResponsableApitech}}</td>
<td>Temps Passé</td>
</tr>
<tr ng-repeat-end ng-show="expanded">
<td></td>
<td colspan="6">
<table class="table table-condensed table-bordered">
<thead>
<th></th>
<th>Tache</th>
<th>Collaborateur</th>
<th>Date</th>
<th>Temps Passé</th>
</thead>
<tbody>
<tr ng-repeat= "ft in ftListesorted" ng-show="expanded" class="collapse {{ft.IdProjet}}">
<td><i class="glyphicon glyphicon-plus"></i></td>
<td>{{ft.NomTache}}</td>
<td>{{ft.NomCollaborateur}}</td>
<td>{{ft.Datefeuillestemps | date : 'dd/MM/yyyy' }}</td>
<td>{{ft.TempsPasse}}</td>
</tr>
</tbody>
</table>
</td>
</tr>
</tbody>
</table>

Answer 1

create expanded property for each row. Change this lines
<button class="btn btn-xs" ng-click="p.expanded = !p.expanded" expand data-
toggle="collapse" id="{{p.IdProjet}}" data-target=".{{p.IdProjet}}">
and
<tr ng-repeat-end ng-show="p.expanded">
