Question

I am looking for scrollable table. It works fine when width is fixed but it doesn’t works while columns are created dynamically.

<table cellspacing="0" cellpadding="0" border="0" width="325">
  <tr>
    <td>
       <table cellspacing="0" cellpadding="1" border="1" width="300" >
         <tr>
            <th>col 1 heading</th>
            <th>col 2 heading</th>
         </tr>
       </table>
    </td>
  </tr>
  <tr>
    <td>
       <div style="width:325px; height:48px; overflow:auto;">
         <table cellspacing="0" cellpadding="1" border="1" width="300" >
           <tr>
             <td>col 1 data 1</td>
             <td>col 2 data 1</td>
           </tr>
           <tr>
             <td>col 1 data 2</td>
             <td>col 2 data 2</td>
           </tr>
           <tr>
             <td>col 1 data 3</td>
             <td>col 2 data 3</td>
           </tr>
         </table>  
       </div>
    </td>
  </tr>
</table>
