Question : Identity column

Hi,
I have Sybase database with many tables. I want one table(say Table1) with identity column. I basically want this column values should be one up number (in sequence with no gap in between). But it seems like the @@identity is at server level so if some other table uses this value, when I insert into Table1, a gap in sequence can occur. Is there anyway to have table level identity value? And not server level?

Answer : Identity column
