I am striving to create a table layout similar to the one shown in the image using bootstrap 5.

My attempt so far looks like this
<table class="table table-bordered">
<thead>
<tr>
<th><span>Domain</span></th>
<th colspan="3"><span>DATE</span></th>
<th colspan="3"><span>DATE</span></th>
<th colspan="3"><span>DATE</span></th>
<th colspan="3"><span>DATE</span></th>
<th colspan="3"><span>DATE</span></th>
<th colspan="3"><span>DATE</span></th>
<th colspan="3"><span>DATE</span></th>
</tr>
</thead>
<tbody>
<tr>
<td><span>Example1</span></td >
<td rowspan="3" ><span>DR</span></td >
<td rowspan="3" ><span>IR</span></td >
<td rowspan="3" ><span>SR</span></td >
<td rowspan="3" ><span>DR</span></td >
<td rowspan="3" ><span>IR</span></td >
<td rowspan="3" ><span>SR</span></td >
<td rowspan="3" ><span>DR</span></td >
<td rowspan="3" ><span>IR</span></td >
<td rowspan="3" ><span>SR</span></td >
<td rowspan="3" ><span>DR</span></td >
<td rowspan="3" ><span>IR</span></td >
<td rowspan="3" ><span>SR</span></td >
<td rowspan="3" ><span>DR</span></td >
<td rowspan="3" ><span>IR</span></td >
<td rowspan="3" ><span>SR</span></td >
<td rowspan="3" ><span>DR</span></td >
<td rowspan="3" ><span>IR</span></td >
<td rowspan="3" ><span>SR</span></td >
<td rowspan="3" ><span>DR</span></td >
<td rowspan="3" ><span>IR</span></td >
<td rowspan="3" ><span>SR</span></td >
</tr>
<tr>
<td><span>Example2</span></td >
<td rowspan="3" ><span>DR</span></td >
<td rowspan="3" ><span>IR</span></td >
<td rowspan="3" ><span>SR</span></td >
<td rowspan="3" ><span>DR</span></td >
<td rowspan="3" ><span>IR</span></td >
<td rowspan="3" ><span>SR</span></td >
<td rowspan="3" ><span>DR</span></td >
<td rowspan="3" ><span>IR</span></td >
<td rowspan="3" ><span>SR</span></td >
<td rowspan="3" ><span>DR</span></td >
<td rowspan="3" ><span>IR</span></td >
<td rowspan="3" ><span>SR</span></td >
<td rowspan="3" ><span>DR</span></td >
<td rowspan="3" ><span>IR</span></td >
<td rowspan="3" ><span>SR</span></td >
<td rowspan="3" ><span>DR</span></td >
<td rowspan="3" ><span>IR</span></td >
<td rowspan="3" ><span>SR</span></td >
<td rowspan="3" ><span>DR</span></td >
<td rowspan="3" ><span>IR</span></td >
<td rowspan="3" ><span>SR</span></td >
</tr>
</tbody>
</table>
However, my current output looks strange as depicted in this image

I am puzzled about what I might be overlooking. I have searched extensively but haven't found a suitable solution. If anyone here can assist me in resolving the issue, I would greatly appreciate it.
Thank you!
