Newbie trying to understand how Tablesorter column headings work

Hi,

I am trying to work out how tablesorter column headings work & where to add some code to hide or deactivate a heading.

I can see from inspector what code I need to add but I cant work out where to put it.

Its like the search row is not recognising there is 10 columns

Code for head is

  1.  <thead>
      <tr>
          <th class="sorter-false filter-false"></th>
       <th style="text-align: center; vertical-align: middle">ColumnB</th>
                <th style="text-align: center; vertical-align: middle">ColumnC</th>
                <th style="text-align: center; vertical-align: middle">ColumnD</th>
            <th style="text-align: center; vertical-align: middle">ColumnE</th>
          <th style="text-align: center; vertical-align: middle">ColumnF</th>
       <th style="text-align: center; vertical-align: middle" class="filter-select filter-exact" data-placeholder="Select">Category</th>
       <th style="text-align: center; vertical-align: middle">ColumnH</th>
       <th style="text-align: center; vertical-align: middle">ColumnI</th>
       <th style="text-align: center; vertical-align: middle">ColumnJ</th>
            <th class="sorter-false filter-false"></th>
            </tr>
     </thead>

<td data-column="10"><input type="search" placeholder="" class="tablesorter-filter form-control disabled" data-column="0" disabled="" data-lastsearchtime="1487115846159"></td>

1st & last columns are supposed to be the same but as per the pic, the second row last column is not the same as the 2nd row 1st column (not in the pic)


I'm using DNN so its not in the traditional spot. Thanks to my mate Jake, Ive played with this in the past to disable the first column (0) but I can remember how I did it.

Thank in advance for any hints that might lead me to the right location or formatting of the head to get it going.
