Hey there,
did you have a look at ng-show and ng-hide: https://docs.angularjs.org/api/ng/directive/ngShow[^]?
This way, you could hide the selected employee in your table:
<tbody>
<tr ng-repeat="empl in employee" ng-hide="{{empl.selected}}">
<td>{{empl.name}}</td>
<td><button value="Select">Select</button></td>
</tr>
</tbody>
Then you could add a click handler for your button that sets the employee's selected attribute.
Hope this helps. If you have further questions, let me know.
