Here's yet another way. You didn't mention what platform you're working on so these commands may not be available:
Code:
ls *import* | cut -c1-3 > file2.txt && pr -m -t -s file1.txt file2.txt | gawk '{print $1"\t"$2"\t"$3}' | sponge file1.txt

The 'ls' command is dumped to file2.txt. The 'pr' command merges the contents of file1.txt (the existing file) and file2.txt. Then we use 'gawk' to display the results, and lastly the sponge utility will allow writing to the same existing file (file1.txt - NOTE: normally this isn't possible, but the sponge utility allow this action.)

file1.txt (before)
Code:
123     456 
789     000 
333     222 
oop     ppo
889     09a

file2.txt
Code:
aaa
bbb
ccc
ddd
fff

file1.txt (after)
Code:
123	456	aaa
789	000	bbb
333	222	ccc
oop	ppo	ddd
889	09a	fff

GIT-COLUMN(1)							    Git Manual							     GIT-COLUMN(1)

NAME

       git-column - Display data in columns

SYNOPSIS

       git column [--command=<name>] [--[raw-]mode=<mode>] [--width=<width>]
		    [--indent=<string>] [--nl=<string>] [--padding=<n>]

DESCRIPTION

       This command formats its input into multiple columns.

OPTIONS

       --command=<name>
	   Look up layout mode using configuration variable column.<name> and column.ui.

       --mode=<mode>
	   Specify layout mode. See configuration variable column.ui for option syntax.

       --raw-mode=<n>
	   Same as --mode but take mode encoded as a number. This is mainly used by other commands that have already parsed layout mode.

       --width=<width>
	   Specify the terminal width. By default git column will detect the terminal width, or fall back to 80 if it is unable to do so.

       --indent=<string>
	   String to be printed at the beginning of each line.

       --nl=<N>
	   String to be printed at the end of each line, including newline character.

       --padding=<N>
	   The number of spaces between columns. One space by default.
