   name          age      date of admission
 Muhammad kashif  20   12/aug/2012
 ali    20    12/aug/2012


but  i want

   name                 age            date of admission
Muhammad kashif    20              12/aug/2012
ali                         20              12/aug/2012



so help me. in my real file i have about ten values so reading then in this strucher is very
difficult. but if these are managed then it is easy.
