None of the solutions here worked for me. Even the example on the datatables homepage did not work hence to the initialization of the datatable in the show option.

I found a solution to the problem. The trick is to use the activate option for tabs and to call fnAdjustColumnSizing() on the visible table:

$(function () {

// INIT TABS WITH DATATABLES
$("#TabsId").tabs({
    activate: function (event, ui) {
        var oTable = $('div.dataTables_scrollBody>table:visible', ui.panel).dataTable();
        if (oTable.length > 0) {
            oTable.fnAdjustColumnSizing();
        }
    }
});

// INIT DATATABLES
// options for datatables
var optDataTables = {
    "sScrollY": "200px",
    "bScrollCollapse": true,
    "bPaginate": false,
    "bJQueryUI": true,
    "aoColumnDefs": [
        { "sWidth": "10%", "aTargets": [-1] }
    ]
};
// initialize data table
$('table').dataTable(optDataTables);

});

I ran into a similar issue when having a div wrapped around the table.

Adding position: relative fixed it for me.

#report_container {
 float: right;
 position: relative;
 width: 100%;
}
