Use the Column Permissions page to set this user's permissions for individual columns in a table or view. Click Add Objects to add database objects to the upper Objects grid. Select each object in the Objects grid, and then set the appropriate permissions in the Permissions grid.
Select or clear the Allow and Deny check boxes to configure the permissions.
Set each type of permission to Grant, With Grant, or Deny or make no selection. Deny will override any other settings. If no setting is selected, permissions, if any, will be inherited from other group memberships.
