Based on the comment of @barmar, I added a <tfoot> at the end of the table.

Inside the <tfoot> I added a <tr> and a empty <td>.

To ensure good use the <td> got a height of 48px and span over the whole table.

To get the last table row it is important not to count the rows of the whole table, but only the rows in body. Codepen is here: Codepen

So finally I can move the tablerows where I want them:-)

Sorry for my poor English:-)
