Easy... A sample input would be:

Also easy. First, an easily readable sample output, without piping
colorization into `column' would be, :

>>   awk '{sub("install|configure|upgrade|trigproc","& _",$3);print}' \
>>   /var/log/dpkg.log | column -t

For the colorized output, ie. the actual raw output and the subject of
the bug report, here are two versions. First, in-line, with the
colorization codes stripped out so that it might be easily readable by
all, and; second, in raw format, as an mail attachment file, to avoid
having the control sequences somehow possibly messing with some hapless
reader's TTY.

! The colorization is not usefully applied, ie. the entire output is
monochrome, but in a color different that the input or normal STDOUT.

That would be a misunderstanding in what `ccze' does. It is specifically
intended for log files only. See, for example, man (1) ccze.

As above, the colorization is not usefully applied, ie. the entire
output is monochrome, but in a color different that the input or normal
STDOUT.

>   $ head -n3 /etc/passwd | column -t -s: | ccze -m ansi -o noscroll

A reasonably colorized output is applied.
