Yes, my previous solutions are both wrong, that's sure Smilie.
We need to fix the FS in order to preserve the null fields.

So, if I'm not missing something again, the correct versions of my previous commands should be:
Code:
awk '
  $1 = $1"\t1\t0\t0\t0"
  ' FS='\t' OFS='\t' infile

Code:
sed 's/^[^       ]*/&    1       0       0       0/' infile1

The sed command contains tabs (^V^I), not spaces.

NAME
column -- columnate lists SYNOPSIS
column [-tx] [-c columns] [-s sep] [file ...] DESCRIPTION
The column utility formats its input into multiple columns. Rows are filled before columns. Input is taken from file operands, or, by default, from the standard input. Empty lines are ignored. The options are as follows: -c Output is formatted for a display columns wide. -s Specify a set of characters to be used to delimit columns for the -t option. -t Determine the number of columns the input contains and create a table. Columns are delimited with whitespace, by default, or with the characters supplied using the -s option. Useful for pretty-printing displays. -x Fill columns before filling rows. ENVIRONMENT
The COLUMNS, LANG, LC_ALL and LC_CTYPE environment variables affect the execution of column as described in environ(7). EXIT STATUS
The column utility exits 0 on success, and >0 if an error occurs. EXAMPLES
(printf "PERM LINKS OWNER GROUP SIZE MONTH DAY " ; printf "HH:MM/YEAR NAME " ; ls -l | sed 1d) | column -t SEE ALSO
colrm(1), ls(1), paste(1), sort(1) HISTORY
The column command appeared in 4.3BSD-Reno. BUGS
Input lines are limited to LINE_MAX (2048) bytes in length. BSD
