Trying to generate an explain plan in SQL Developer, the program puts up a message box with title "failed to query plan_table" complaining "invalid column name". The plan is not generated or displayed. How to fix?

Execute this sql statement:

drop table plan_table

SQL Developer automatically regenerated the proper table & displayed the correct plan after pressing F6 again.
