The Permissions tab of the View property sheet has the following components:
Permissions list Lists the users who have permissions on the view. If you want to add users to the list, click Grant. To remove a user from the list, select the user, and then click revoke. You can select multiple users by holding Shift while you click.
To grant or revoke permissions for a specific user, click the fields beside each user. Double-clicking (so that a check mark and two + signs appear) gives the user grant options.
Grant Displays the Grant Permission dialog, which lets you grant permissions on the table to other users.
Revoke Revokes permissions from the users and removes them from the Permissions list.
