Change Datatables Header & Footer Width

BrkCoder

Hi, I am building Database table using the following code:
[code]

var j$ = jQuery.noConflict();
j$(document).ready(function()
{
j$('.reporstDT').dataTable(
{
'bJQueryUI': true,
'bFilter': false,
"bLengthChange": false
});
} );

[/code]

and then I am calling the above script using tag & adding Class="reporstDT" to HTML5 table.
The problem is that the width of the generated table doesn't match my html table, as a result of this I get the following result:

Can I configure the datatables header width and footer width properly without change their css styling?
