I’m a little late to respond here but I also was looking for this type of functionality between Caldera and Tablepress. This gentleman Desertsnowman has already done the legwork.This is the method I’ve used to populate tablepress tables from caldera forms.
This link includes the plugin .php code and instructions.

I can assure you it does work as I am employing it on mainetuna.org
Good luck!
