Sorry, but this is very basic stuff. Someone here might help you, but whil you wait I would suggest you google for an access tutorial on tables. It will take you 10 minutes and you are done. And don't forget to look in the help file (press F1) there might be some "How to" too. Finally you have the Access application itself. There is no death penalty on scouring around and trying things out.
My main point is that you need to do some basic work yourself, and learn how to do it. Both Help and Google are sufficient for that. Come back with questions for things that are not immediately available in either Help nor Google.
