Fix the row and column as header dynamically in html without modifying the code [on hold]

I have a html page which contains a table in it and I have add that page into my asp.net project. Now I want freeze the panes(fix 1st five rows as header and 1st column) without modifying the html page..

In that html page the table did not contain 'thead', 'tbody' and 'th' tags.

It just like this...

 <table>
   <tr>
      <td></td>
      <td></td>
      <td></td>
    </tr>
    <tr>
      <td></td>
      <td></td>
      <td></td>
    </tr>
 </table>

I don't want to add 'th', 'thead' tags to my html page... because I don't want modify my page... I think we may add them and freeze the panes dynamically.....
