Actually this kind of problem has come out many times, I think we should
distinguish `column name` and ```column path(which respects "." and "`")```,
and have 2 methods that can parse `column name` and `column path` respectively.
Currently we only have a `resolve` method that can parse `column path`, we
should add one for `column name` and go through all `DataFrame` APIs to fix
stuffs that should be `column name` but handled as `column path`
