make a colum fixed width

[detox]

I am attempting to make a column on a webpage fixed width but am unsure how.

in the php file, in the </table> section, ther column I want to change is:
<th class="sv_title" align="left"><?php echo JHTML::_( 'grid.sort', JText::_('RS1_MYBOOKINGS_SCRN_RESID_COL_HEAD'), 'resname', $direction, $ordering); ?></th>

I read the command is td width ="100px" but not sure how to insert

Can someone help with this info, or should I provide a link in pastebin with the complete php file?

Thanks

you can use the same attributes/styles for <td> and <th>:

<td width="100">
<th width="100">
<th style="width:100px">
