combine multiple files by column into one files already sorted!

I have multiple files; each file contains a certain data in a column view
simply i want to combine all those files into one file in columns

example

file1:
Code:
a
b
c
d



file 2:
Code:
1
2
3
4



file 3:

Code:
G
H
J
K



The output file should be like this
out_file:
Code:
a   1  G
b   2  H
c   3  J
d   4  K



anyone can support me please? kindly note that I want to use the fastest shell program as my files include many many # of records (the above is just an example actually I'm talking about ~ 1000 record per file)

also there is no any kind of matching test required as the files are containing the same number of records and already sorted
