Manually resize a fixed column of FixedColumns plugin

foolishbrat

Using this script I can scroll the 2nd columns onward and let 1st column (First name) fixed.

$(document).ready(function() {
    var table = $('#example').DataTable( {
        scrollY:        "300px",
        scrollX:        true,
        scrollCollapse: true,
        paging:         false
    } );
    new $.fn.dataTable.FixedColumns( table );
} );

How can I manually resize the first column?
