Subject: Please help with fixing output

Hi all,

I'm having trouble with a hash output.

The original files are:
File 1
ALPHA|OMEGA|GAMMA
1|2|3
4|5|6

File 2
EPSILON|GREEK|OMEGA|BETA
7|8|9|0
12||13|
10|11|5|15


and I'm using the following code:

 sets = Hash.new { | h, k | h[k] = [] } # hash that contains a new
array
                                        # for every new key
 %w(file1.txt file2).each do | filename |
   File.open(filename) do | f |
     names = f.gets.chop.split('|')
     f.each do | line |
       names.zip(line.chop.split('|')).each do | name, value |
         sets[name] << value.to_i if value and value !~ /^\s*$/
       end
     end
   end
 end

 sets.values.each { | a | a.uniq! }

 puts sets.keys.map { | k | '%8s ' % k }.join('|')

 rows = sets.values.map { | a | a.size }.max

 (1..rows).zip(*sets.values) do | row |
  row.shift
   puts row.map { | v | if v then '%8s ' % v else ' '*9 end }.join
('|')
end

but the output seems a little strange and I'm not sure why that is.

Output should be
   ALPHA | OMEGA |   GAMMA | EPSILON |   GREEK |    BETA
       1 |       2 |       3 |         |         |
       4 |       5 |       6 |    10   |      11 |       15
         |       9 |         |      7  |       8 |        0
         |      13 |         |      12 |         |

instead it gets:
   ALPHA |   OMEGA |   GAMMA | EPSILON |   GREEK |    BETA
       1 |       2 |       3 |       7 |       8 |       0
       4 |       5 |       6 |      12 |      11 |      15
          |       9 |         |      10 |         |
          |      13 |         |         |         |

Please advise on what's going on.

Thanks
