Problem

Manually (using OS clipboard) Copy/Paste a table from a page to another content such as Comment or Page can strip header information.

Environment

Reproduced in Confluence 8.5.9

Steps to Reproduce

1. Create a Page on which you define a 4x2 Table
   • I am adding the default storage format generated for my Confluence 8.5.9 instance

     <table class="wrapped">
       <colgroup>
         <col/>
         <col/>
         <col/>
         <col/>
       </colgroup>
       <tbody>
         <tr>
           <th scope="col">test1</th>
           <th scope="col">test2</th>
           <th scope="col">test3</th>
           <th scope="col">test4</th>
         </tr>
         <tr>
           <td>1</td>
           <td>2</td>
           <td>3</td>
           <td>4</td>
         </tr>
       </tbody>
     </table>
     

1. Copy the table manually using keyboard shortcut such as CTRL+C or Mouse right click>Copy
2. Paste/CTRL+V the content in another Comment or page

Expected Results

The copy/paste + save content operations should preserve the header information of the table

Actual Results

The copy/paste + save content operations are not preserving the header information of the table

Workaround

Copying the entire page could be an alternative or manually adding back the header information.

Update: Another found alternative is to copy the table in Edit mode from the source page. This maintains the format and headers.
