Hi,
thanks for your question, and sorry for the late answer. As I was on vacation, I didn't have a chance to reply earlier.
To be honest, I don't really understand. TablePress can only maintain static tables, and if you want different tables in the sidebar of different pages, you will need to use different Shortcodes, e.g. in a text widget that checks the page ID with the help of a plugin like Widget Logic.
Regards,
Tobias
