The page allows you to grant additional access to tables by users, beyond
what is available in User Permissions or Database Permissions.
The permissions granted here apply only to access to one table in one database
by one user, thus allowing quite fine-grained access to be granted.
To add new table permissions, you must first select the database that the
table is in using the form at the bottom of the page. Then click the
Add new permissions button to bring up a form for selecting the
table and other details.
