Matching corresponding columns in two different files

Hi to all,
I have two separated files:

FILE1
Code:
"V1"        "V2"         "V3"
Mary      James      Nicole
Robert   Francisco   Sophie
Nancy     Antony     Matt
Josephine Louise     Rose
Mark                    Simon
                           Charles

FILE2
Code:
"V1"        "V2"         "V3"
Mary      James      Nicole
Nancy    Francisco   Sophie
Josephine               Rose
                           Simon


FIL2 is a subset of FILE1 and the two files have exactly the same header! The columns of each file are of different length in the same file and between FILE1 and FILE2. I just want to show the differences between the two files column by column. So the output I want is:

FILE3
Code:
"V1"             "V2"             "V3"
Robert          Antony          Matt
Mark            Louise           Charles

I hope someone can help me...
Thanks in advance!!!!!!

Eleonor

NAME
meld - Visual diff and merge tool for the GNOME Desktop SYNOPSIS
meld [options] meld [options] FILE1 meld [options] DIR1 meld [options] FILE1 FILE2 [FILE3] meld [options] DIR1 DIR2 [DIR3] DESCRIPTION
Meld is a graphical diff viewer and merge application for the Gnome desktop. It supports 2 and 3-file diffs, recursive directory diffs, diffing of directories under version control (Arch, Bazaar, Codeville, CVS, Darcs, Git, Mercurial, Monotone, RCS), as well as the ability to manually and automatically merge file differences. OPTIONS
--auto-compare, -a Automatically compare all differing files on startup. --diff FILE1|DIR1 FILE2|DIR2 [FILE3|DIR3] Create a diff tab for the given files or directories. Note that "meld --diff FILE1 FILE2" is functionally equivalent to "meld FILE1 FILE2". However, the --diff argument can be given multiple times for one invocation of meld which allows the user to automatically initiate multiple diffs when meld starts. See examples below. --help, -h Print application help and usage. --LABEL=<label>, -L <label> Set application window title to <label>. --version Print application version and exit. EXAMPLES
meld Run meld without initiating a diff. meld FILE1 Initiate a diff between FILE1 and the version-controlled copy of FILE1. meld DIR1 Initiate a recursive diff between DIR1 and the version-controlled copy of DIR1. meld FILE1 FILE2 Initiate a diff between FILE1 and FILE2. meld FILE1 FILE2 FILE3 Initiate a 3-way diff between FILE1, FILE2, and FILE3. meld DIR1 DIR2 Initiate a recursive diff between directory DIR1 and DIR2. meld DIR1 DIR2 DIR3 Initiate a recursive 3-way diff between directory DIR1, DIR2, and DIR3. meld --diff FILE1 FILE2 --diff FILE3 FILE4 Initiate a diff between FILE1 and FILE2, and a separate diff between FILE3 and FILE4.
