First let me admonish you gently. Users should never be looking at data in
tables. Tables are for storing data only. Microsoft designs great programs,
but unfortunately, they are not professional database programmers and they
often succumb to suggestions from their marketing department. Just because
it's possible to do something, doesn't mean it's good to do. I could explain
why, but that shouldn't be necessary.
Second, let me remind you that subdatasheets cause extremely poor
performance. You probably won't notice with a small amount of records, but
it will be very noticeable as the number of records grows. Again, explaining
why shouldn't be necessary.
So now that I've hopefully changed your mind, let me tell you how to do what
you want. Open the table in Design View. Right-click and choose properties.
Look for the subdatasheet property.
