I did not understand that you need the column number of the match. That
could perhaps become a feature request for GNU grep: with -o and -n, also
print the column number of the first character.
That being said, if you truncate the N first characters of the matching
line, you have to parse the original line (that is, not the line that grep
or another tool outputs) to find the matches anyway.
