Verify if a table exists or not

Can I ask you a question? I have an
Access db and working with ASP I’d like
to be able to verify if a table exists
on my db and if not to create it on the
fly. For the creation I have no
problem, but I can’t verify the
existence of the table with SQL; how
can I do? I read about the object
sysobjects, but I can’t use it. Can you
please suggest me how can I do?
Thanks to all
Fabrizio
