Please be way more specific. What does "where the different is > 1" mean? How does this show up in your desired output? Which of the four lines should be printed? In your attempt, you reference $10 which doesn't exist in your input sample, and only in the first line, although empty, in your desired output.

Hi all !
If there is only one single value in a column (e.g. column 1 below), then return this value in the same output column.

COLCRT(1) BSD General Commands Manual COLCRT(1)
NAME
colcrt -- filter nroff output for CRT previewing
SYNOPSIS
colcrt [-] [-2] [file ...]
DESCRIPTION
The colcrt utility provides virtual half-line and reverse line feed sequences for terminals without such capability, and on which overstrik-
ing is destructive. Half-line characters and underlining (changed to dashing `-') are placed on new lines in between the normal output
lines.
The following options are available:
- Suppress all underlining. This option is especially useful for previewing allboxed tables from tbl(1).
-2 Cause all half-lines to be printed, effectively double spacing the output. Normally, a minimal space output format is used which
will suppress empty lines. The program never suppresses two consecutive empty lines, however. The -2 option is useful for sending
output to the line printer when the output contains superscripts and subscripts which would otherwise be invisible.
ENVIRONMENT
The LANG, LC_ALL and LC_CTYPE environment variables affect the execution of colcrt as described in environ(7).
EXIT STATUS
The colcrt utility exits 0 on success, and >0 if an error occurs.
EXAMPLES
A typical use of colcrt would be
tbl exum2.n | nroff -ms | colcrt - | more
SEE ALSO
col(1), more(1), nroff(1), troff(1), ul(1)
HISTORY
The colcrt command appeared in 3.0BSD.
BUGS
Should fold underlines onto blanks even with the '-' option so that a true underline character would show.
Cannot back up more than 102 lines.
General overstriking is lost; as a special case '|' overstruck with '-' or underline becomes '+'.
Lines are trimmed to 132 characters.
Some provision should be made for processing superscripts and subscripts in documents which are already double-spaced.
Characters that take up more than one column position may not be underlined correctly.
