I'll have a look at it :-) Of the top of my head I am not sure why that is!

New version is due out in the next few days. The changes will be :

1. Sorting out the issue with the language files that Diva pointed out.
2. Adding an inner div to the column cells to allow easier styling.
3. Sorting out the fact that the first row of boxes is 'th' rather than 'td'.
4. Adding the ability for the user to switch between columns and rows.
