Get index of row in table using angularJS

Question

I want to get index of each row in this table using angularJS

<table>
<tbody>
  <tr ng-repeat = "cust in costomers">
     <td> cust.name </td>
     <td> cust.phone </td>
     <td> cust.address </td>
  </tr>
</tbody>

I want to have a variable that contains the index of each row not to just display it
