Vertical headings in matrix table (modern layout)

If above does not work, the following can be used:

<br />

<table style="border-collapse: collapse; width: 100%;">

<tbody>

  <tr>

   <td style="vertical-align: middle; border: 0px solid black; transform: rotate(270deg); text-align: center;">Hej Laura!</td>

  </tr>

</tbody>

</table>
