I am trying to make this table in HTML without using CSS, but I am not getting the desired output. I have tried a bunch of other combinations for the row with 6:2:3 rowspan.
This is the desired output 
This is the code I am using.
<!doctype html>
<html>
<head>
<title>Table</title>
</head>
<body>
<table border="1">
<tr>
<th rowspan="3"> </th>
<th colspan="3"> </th>
</tr>
<tr>
<th colspan="2"> </th>
<th rowspan="2"> </th>
</tr>
<tr>
<th> </th>
<th> </th>
</tr>
<tr>
<td rowspan="2"> </td>
<td rowspan="2"> </td>
<td rowspan="2"> </td>
<td > </td>
</tr>
<tr>
<td > </td>
</tr>
<tr>
<td rowspan="6"> </td>
<td rowspan="2"> </td>
<td rowspan="2"> </td>
<td rowspan="3"> </td>
</tr>
<tr>
<td rowspan="2"> </td>
<td rowspan="2"> </td>
</tr>
<tr>
<td rowspan="2"> </td>
<td rowspan="2"> </td>
<td rowspan="3"> </td>
</tr>
<tr>
<td> </td>
<td> </td>
<td> </td>
<td> </td>
</tr>
</table>
</body>
