[jQuery] TableSorter Issue: Text with % (percent) in row of table breaks sorting of the column

[jQuery] TableSorter Issue: Text with % (percent) in row of table breaks sorting of the column

Hello there,

I am having a bizarre problem where if the following occur:
  1. There exists a table with the tablesorter js applied e.g. http://tablesorter.com/docs/index.html#Demo
  2. There is a text column within the table e.g. Last Name, of above table
  3. There is a %  (percent) in the first (as specified by html not the js sorting) row of this column e.g. Almighty %
...the sorting works for this column only on the first click. After that it appears like it does not work.

The text in this column is not percentage, but text that might have a %, in it so the percent parser cannot be applied to this column.

If the % appears in a lower down row than the first sometime the sorting works and sometimes it does not, but it consistently does not work if the %  is in the first row.

Has anyone got a solution to this?

Many thanks cool JS bods.
