I wrote an implementation using the Matrix class, but it didn't really
make it any shorter/cleaner/DRYer. I think your code is fairly DRY
already. The only thing I might suggest is extracting your
justification, e.g.

def justify(obj,w)
  case obj
  when Fixnum
    obj.to_s.rjust(w)
  else
    obj.to_s.ljust(w)
  end
end
