Libre Office 7.0.3.1, on Macbook pro OS 11.0.1, with Java Version 8, update 271.
Base unusable owing to several different Libre Office Java-related error messages which occur when trying to enter data/edit Table.
Have not included error messages (have screen shots), as am hopeful that answers to the 2 questions will resolve problem. (Also, I’m unsure at the moment how to include screen shots.)
