Create SQL Server data source to table rather then whole database

Pretty much what it says in the title. I can successfully create a data source for our entire Production database, but I'd prefer to point towards the actual table I need since the database is huge. Not sure how to configure an Other parameter to do this. I tried "Table", "Name" and "TableName" so far with the table's name, so far no joy.

We're running SQL Server version 14.
