datatable styleing css

Question

I want to style my datatable using ThemeRoller . already enabled jQuery UI ThemeRoller support in my datatable. I have only one row on the top and the Pagination numbers are styled fine. but i dont see any style on the rows, they are all the same. Is that the default setting or i am missing something.

$(document).ready(function(){
 $("#courses_list").dataTable({
  "bSort": false,
  "bLengthChange": false,
  "bSortClasses": false,   
  "bFilter": false,
  "bStateSave": true,
  "bAutoWidth": false,
  "bJQueryUI":true,
  "sPaginationType": "full_numbers"
  });

});

Any good practice of doing that is apprieciated.
