How to increase column width of particular column fields?

creativeweblogo

Actually I am using a datatable with 12 columns and I need to increase width of four columns but I can’t be able to do that.

I have used css on table td but it is not working.

Like –

Member Name



And also use jquery to increase the width but it’s not working –

"aoColumnDefs": [

{ "sWidth": "20%", "aTargets": [ 0, 2, 5, 8 ] }

]



Please suggest us how i can solved that problem.
