How to reproduce

• Go in edition
• Insert a table
• In advanced tab, choose to fix the column width
• Try to change the columns width to 80px

Actual behavior

• Visually this has no effet,
• the width input is set to 151px instead of 80px (see screenshot),
• but the source code seems correct :

  <table class="simple">
  <tbody>
  <tr>
  <td style="width: 80px;">
  <p style="width: 151px;">Head 1</p>
  </td>
  <td style="width: 80px;">
  <p style="width: 143px;">Head 2</p>
  </td>
  <td style="width: 80px;">
  <p style="width: 112px;">Head 3</p>
  </td>
  </tr>
  <tr>
  <td style="width: 80px;">
  <p style="width: 152px;">Cell 1</p>
  </td>
  <td style="width: 80px;">
  <p style="width: 142px;">Cell 2</p>
  </td>
  <td style="width: 80px;">
  <p style="width: 112px;">Cel2</p>
  </td>
  </tr>
  </tbody>
  </table>
  

• if you save the content, the columns width are corrects
• if you re-edit the content, it works fine
