Review Comment:
My original thought is to simplify large long column on doctest(less
readable), like this:
https://github.com/Eason0729/datafusion/blob/4dd44c5a2b0d9810d7e9163689afab227c58d542/datafusion/core/src/dataframe/mod.rs#L734
Therefore, I simplify example_long.csv in the next commit to the point which
is just enough to showcase most method on dataframe.
