[racket] Output Different Column Widths in a Table

`pretty-print' is not really meant to print tables. You probably want to
use `~a' instead, which has various arguments related to width:
http://docs.racket-lang.org/reference/strings.html?q=~a#%28def._%28%28lib._racket%2Fformat..rkt%29._~7ea%29%29

For example:
(for ([s '("auie" "bépoauie" 5 10)]
      [w '(10 4 8 2)])
  (display (~a s #:width w)))
