If you want selective table permissions you MUST
‘REVOKE’ permissions and reset specific..

The following set I use all of the time

When accounts are made permissions are set with a * and are NOT overriden by revoking against and setting permissions against specific tables.

YOU MUST revoke default set under *

Revoke SELECT,INSERT,UPDATE,DELETE ON database-name.* FROM ‘ac-name’

Revoke any set against specific table
Revoke SELECT,INSERT,UPDATE,DELETE ON database-name.TestTable FROM ‘ac-name’

Grant permissions set agianst specific table
Grant SELECT,INSERT,UPDATE,DELETE ON database-name.TestTable TO ‘ac-name’
