I'm trying to combine the cells G and H into one, let's see my code for the follow table:

<table border="1">
<thead>
<tr>
<th>Header</th>
<th>Header</th>
<th>Header</th>
<th>Header</th>
</tr>
</thead>
<tbody>
<tr>
<td rowspan="5">A</td>
<td colspan="3">B</td>
</tr>
<tr>
<td colspan="2">C</td>
<td rowspan="4">D</td>
</tr>
<tr>
<td rowspan="3">E</td>
<td>F</td>
</tr>
<tr>
<td>G</td>
</tr>
<tr>
<td>H</td>
</tr>
</tbody>
</table>
How can I do? I try to do <td rowspan="2">G</td> but it doesn't work.
What I want is:
Is there a way to make that table I want, using only HTML?
