I have the following table structure:
<table>
<thead>
<tr>
<th colspan="4">Current</th>
<th colspan="4">New/Requested</th>
</tr>
<tr>
<th nowrap="nowrap">RSD </th>
<th nowrap="nowrap">CRSD </th>
<th nowrap="nowrap">MSD </th>
<th nowrap="nowrap">Open QTY </th>
<th nowrap="nowrap">CRD </th>
<th nowrap="nowrap">CRSD </th>
<th nowrap="nowrap">MSD </th>
<th nowrap="nowrap">Open QTY </th>
<th nowrap="nowrap">Action</th>
<th nowrap="nowrap">Reason</th>
<th nowrap="nowrap">Action Code Status </th>
</tr>
<tbody>
<tr>
<td></td>
<td></td>
.....plenty of rows
</tr>
</tbody>
</thead>
</table>
I am trying to fix the header so that if I scroll down it stays visible. I looked at this post but couldn't understand it. How can I do this?
