Matching corresponding columns in two different files

Hi to all,
I have two separated files:

FILE1

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

FILE2

"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

"V1"             "V2"             "V3"
Robert          Antony          Matt
Mark            Louise           Charles

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

awk ' {if(NR==1) { print $0}  # print one line of header
         arr[$0]++          
        }
        END {for(i in arr) { if(arr==1) {print i} }   } '   FILE1 FILE2 > FILE3

Try this

I tried but the output is not exactly what i'm searching for..The code gives me an output with: two identical matrix with the common elements between the two files and a third matrix that put together the first matrix elements plus the second matrix elements...I desire an output showing me only the differences between the two matrix column by column..anyway thank you so much!
