<html> <head> <script type="text/javascript">     function myfun(e){       if(!e.target) alert(e.srcelement.innerhtml);       else alert(e.target.innerhtml); }  </script>  </head>  <body>  <table id="tableid" onclick="myfun(event)" border="1"> <tr>  <td>row 1, cell 1</td>  <td>row 1, cell 2</td> </tr> <tr>  <td>row 2, cell 1</td>  <td>row 2, cell 2</td> </tr> </table> </body> </html>

i guessing need mousevents thats sure of please help?

you use :nth-child() selector, e.g third column:

demo jsfiddle

$('table').find('tr :nth-child(3)').on('click', function(){     alert('third column clicked!'); });

you exclude header cell:

$('table').find('tr :nth-child(3):not(th)')
