How design report dynamically using crystal reports?

Hi to all,

I have designed one report for one user with some fields,

all users are having same fields.

if one user details are in table,particular design is comming with that data
if another user details are in table,particular design is will come with  user1,user2
how many users are in table,all user details will show in one report?
all user are having same design and layout


How?

thanks inadvance
