Correct me if I’m wrong, but I am doing the same in my code.

```auto
 <tbody>
 <tr ng-repeat="row in msg.payload">
 <td ng-repeat="item in row track by $index" >{{item}}</td>
 </tr>
 </tbody>

```

And this is the same approach [as you do in your post here](https://discourse.nodered.org/t/how-set-the-output-variable-msg-payload-in-js/657/22?u=petr)
