Re: Finding Text In Specific Columns

Perhaps matchadd can help - the original poster seems to want to
highlight multiple items at once

:call matchadd('ErrorMsg','\_^\%([^\t]*\t\)\{4}\zs[^0]')

The above line marks every 4th col that's NOT 0 in error color - red
You can run the above command for all the columns where you want this
to be applied.
