Subject: Help with Multi Dimensional Array

I'm new to ruby and have been trying to figure out what I'm doing
wrong.

I'm completely stumped about how to merge two files together based on
whether they share the same key or not.

Example:

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

End result should be:

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



Currently I have tried this:

array_file1 = []
array_file2 = []

row = 0
IO.foreach("file1.txt" ) {
  |line|
  array_file1[row] = line.split("|")
  row += 1
  }

row = 0
IO.foreach("file2" ) {
  |line|
  array_file2[row] = line.split("|")
  row += 1
  }
N = array_file1.length
array_file1.times(N) { |row|
   if array_file1[row][1] == array_file2[row][2]
  array_file2[row].each{
    |col|
     array_file1[row][array_file1i[row].length] = col
  }
   end
}

But I get Undefined Method

Logically, I want to
  loop through row of array_file 1{
     check to see if array_file1.OMEGA is equal to array_file2.OMEGA
       loop through column
           insert contents of array_file2 to end of array_file1
       end loop
 end loop


Any help would be greatly appreciated!
