gVim里能否设置类似UE（UltraEdit）里的列标记

如题，gVim里能否设置类似UE（UltraEdit）里的列标记，就是在某些列上设置一条竖线

竖线没有，改颜色倒是可以

New in Vim 7.3:

'colorcolumn' is a comma separated list of screen columns that are highlighted with ColorColumn. Useful to align text. Will make screen redrawing slower. The screen column can be an absolute number, or a number preceded with '+' or '-', which is added to or subtracted from 'textwidth'.

Example from the docs:

:set colorcolumn=+1        " highlight column after 'textwidth'

:set colorcolumn=+1,+2,+3  " highlight three columns after 'textwidth'
:highlight ColorColumn ctermbg=lightgrey guibg=lightgrey

You can use absolute numbers as well:

:set colorcolumn=80
