Make 2 buttons inside a table cell be next to each other

I have the following code :

      <td>
        <button class="btn btn-primary btn-xs" ng-click="r.changeView('requests/edit/' + request.id)">
          <i class="fa fa-pencil-square-o"></i>
        </button>
        <button class="btn btn-primary btn-xs" ng-click="r.changeView('requests/edit/' + request.id)">
          <i class="fa fa-step-backward"></i>
          <i class="fa fa-step-forward"></i>
        </button>
      </td>

They appear on 2 different lines.

How can I make them appear next to each other on the same line ?

I tried a few things with float and display but without success.

If I add that code in a snippet the buttons are next to each other, so it's hard to reproduce:

<table>
  <tr>
    <td>
      <button class="btn btn-primary btn-xs" ng-click="r.changeView('requests/edit/' + request.id)">
        <i class="fa fa-pencil-square-o"></i>Button1
      </button>
      <button class="btn btn-primary btn-xs" ng-click="r.changeView('requests/edit/' + request.id)">
        <i class="fa fa-step-backward"></i>
        <i class="fa fa-step-forward"></i>Button2
      </button>
    </td>
  </tr>
</table>

The buttons are already displayed as inline-block. Maybe the table isn't wide enough; if so, You could try <td style='white-space: nowrap'>.
