I had deleted several tables from a MySQL database but when I opened phpMyAdmin, those tables were still showing under the structure tab. These tables would not appear in the side nave nor were they accessible. The structure view simply refused to let go of those tables. I ran the following query and they finally disappeared.
SHOW TABLE STATUS
After running that query, phpMyAdmin returned the status of all the tables. As you might expect the deleted tables were not there, once I returned to structure view those tables were finally gone.
