No need to merge, just use this:

Code:
 awk '$0=($0?$0:0)" \t"' infile

the tabs are not alliged properly to make it a seperate field

output:
1(tab)
2(tab)
10(tab)

desired output:
1 (tab)
2 (tab)
3 (tab)
10 (tab)

Could post the output from the following command:

Code:
awk '$0=($0?$0:0)" \t"' infile|cat -te

I get this:
Code:
% awk '$0=($0?$0:0)" \t"' infile|cat -te
1 ^I$
2 ^I$
3 ^I$
0 ^I$
5 ^I$
0 ^I$
6 ^I$

digit -> space -> tab

Is this the desired result?

May be this illustrates it better:

Code:
% awk '$0=($0?$0:0)" \t"' infile|od -cbw4  
0000000   1      \t  \n
        061 040 011 012
0000004   2      \t  \n
        062 040 011 012
0000010   3      \t  \n
        063 040 011 012
0000014   0      \t  \n
        060 040 011 012
0000020   5      \t  \n
        065 040 011 012
0000024   0      \t  \n
        060 040 011 012
0000030   6      \t  \n
        066 040 011 012
0000034

Or perhaps you want something like this?
(adjust the length if you need: -10, -15, -20 ...)

Code:
awk '$0=sprintf("%-15s",$0?$0:0)' infile
