tfoot renders after thead and before tbody

Allan, I noticed this at http://www.datatables.net/usage/:

"Defining the 'tfoot' section is optional from the view point of DataTables, and if defined will be used in a similar manner to how thead is used, with the exception of not being able to use it to sort data."

In my original markup the tfoot node comes after tbody, but when dataTables renders it, it's moving tfoot between thead and tbody. Is there a setting somewhere where i can keep it at the end?

thanks again for a great plugin, it's really amazing.
