How to restrict one user from accessing a table, whereas the user's group has access

Hi,

It may be a strange requirement but that's a fact. I need to restrict one partcular user from accessing one object (say a Table) . But the group, in which the user belongs to, has got access for the table. Is it doable in teradata ?

Thanks,

Subhayu
