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
