Hide and/or Show Table Columns
I need a table that can display only certain columns depending on whether a check box is selected or not. If selected, I want all columns to show. If not selected, I need it to show only the "weekly" class columns. **I want to use as little JavaScript (if any) as possible and needs to be cross-browser compatible**.

     <table>
       <tr class="weekly">
         <td></td>
       </tr>
       <tr class="overall">
         <td></td>
       </tr>
     </table>
     <input type="checkbox" name="data" value="Show Overall Data"  />

Simply put, I need a table that will hide and show certain columns depending on what the check box status is.

Also, I am not good with coding so I would need someone to paste the entire code including HTML tags and what not.
