The Options tab of the Table Editor shows the items as can be seen below.
Microsoft SQL Server Table Options
Editing the primary key name is only useful for tables that don't have one yet.
Use the Owner box to select the owner of the table, this will be dbo by default.
The filegroup box displays the available filegroups you can use to store the table data.
Note:
The Owner box will not be visible for Microsoft SQL Server 2005 and up and each table will then belong to a schema instead.
