Can I migrate .tab data files from FMP to Base tables?

I wish to migrate exported data from several tables in a File Maker Pro database and link them as tables in Base. I have tried opening .tab data files directly in Base, and while they open as tables, I can’t find a way to modify their structure so as to link them into a database. Is it possible?
(Mac OS 10.14)
