Sorry, I am new to sorting and jquery. I am using your table example with the following sort expression:

$('#myTable>tbody>tr').tsort('td:eq('+nr+')[abbr]', {order:aAsc[nr]});

I have same date value in td and abbr attribute. Sorting is not working fine.

I tried putting yyyymmdd values in abbr attributes. Didn't work. Does abbr values matter?

Could you please improve above sort expression to make it work fine. Thanks already for the plugin.
