Table privileges
At the table level, you can control which operations each user access level (1–8) can do:
View records in a table (read privilege)
Change table record contents (update privilege)
Append new records to a table (extend privilege)
Delete records from a table (delete privilege)
When you create a table privilege scheme, all four table privileges are granted initially. That is, all table access levels are 1 by default (1 being the least restrictive level).
