tbody.collapse.in {
  display: table-row-group;
}

You can not use tbody inside another tbody it is not legal HTML.

However, you are allowed to have multiple TBODY elements in a single TABLE element, so you could do this:

<table> 
  <tbody> 
    <tr> 
      <td>...</td> 
      <td>...</td> 
    </tr> 
  </tbody>
  <tbody > 
    <tr> 
      <td>...</td> 
      <td>...</td> 
    </tr> 
  </tbody>
  <tbody> 
    <tr> 
      <td>...</td> 
      <td>...</td> 
    </tr> 
  </tbody>
</table>
