perhaps for `combine` and `ByRow` we should re-size tables ``` julia> df = DataFrame(a = [1, 2]); julia> combine(groupby(df, :a), :a => (t -> [100, 200]) => :b) 4×2 DataFrame...
I'm currently working on a small implementation of a `Tables.AbstractRow`. It's basically a wrapper around an `OrderedDict` which is a `Tables.AbstractRow` and defines all the convenience methods of a `DataFrameRow`,...
https://github.com/JuliaData/DataFrames.jl/pull/2881 > need page(s) about indexing and select/transform/... which would be more detailed than Getting Started, but less technical that the API reference.
