[jQuery] table sorter issue, how do i sort these as a currency

[livewire9174]

Hi,
I am using this to initialise the page

<SCRIPT type=text/javascript>
        $(document).ready(function() {
            $("#tableOne")
                        .tablesorter({ debug: false, sortList: [[0, 0]], 
widgets:
['zebra'] })
            .tablesorterPager({ container: $("#pagerOne"),
positionFixed: false })
          });

</SCRIPT>


I have a row in the table which is a european currency, how do I sort
by this?
