To append a field of autonumber into a new table

[lizzywu]

I have the field called subject_id which is autonumber in the form of 10001,10002,... And I want the field with the same format to appear in another table. But appending it leads to different numbering, i.e. the filed becomes 1, 2, ... instead of 10001, 10002 as I've formatted it in its original table.
How could I append/copy such a field?

Thank you very much!

You mean the autonumber in the first table started with 10001?
