            <td>
                <div class="form-group">

                <div class="form-actions">
                    <button type="submit" ng-disabled="form.$invalid" class="btn btn-danger">Place order</button>
                </div>

            </td>                       

        </tr>
    </tbody>
</table>

Please note that tag is inside first (i.e.first column). I want to make second column fields also the part of this form.

Where should i move form tag now. i tried putting it just after , but its not working, as i think after first tag should be

I am also ok to use container, row and column classes of twitter bootstarp, but there also the same problem (everything should be inside column class)

Please help me on this.
