Is it possible to use tfoot cells to sort table data?

Abatap

Hello. One of the legacy manuals says the following: "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.".

And, as far as I can tell, this stays true even for the most recent version of the plugin.

So, is there a quick way (such as adding some class definition or setting some option in my js code) to enable sorting function for tfoot cells, the same way it's assigned to thead elements out of box?
