to use datatables with my code

You mean Datatables.js, don't you?
It requires this structure for your table:

Code:

<table id="myId">
 <thead>
   <tr><th>Heading1</th><th>Heading2</th></tr>
 </thead>
 <tbody>
   <tr><td>Cell1.1></td><td>Cell1.2</td></tr>
   <tr><td>Cell2.1></td><td>Cell2.2</td></tr>
 </tbody>
</td>

Wouter60 , Yes dear i have used this structure only but datatable isnt working.
