jquery table sorter

Hi,

I am using http://tablesorter.com/docs/ and I get this error with jquery 1.6.1:

table.config.parsers[c] is undefined

http://localhost/mySite/public/js/jquery-1.6.1.min.js/eval/seq/3

Line 398

full error:

table.config.parsers[c] is undefined

(?)(table=table#myTable.tablesorter, sortList=[[undefined, 0]], cache=Object { row=[5], normalized=[5]})3 (line 398)

(?)()3 (line 601)

[Break On This Error] (398 out of range 106)

The plugin isn't working at all...

With an older version of table sorter I dont have the error...
