Migrating to the Arrow mono-repo

1

Discussion on discourse [here](https://discourse.julialang.org/t/arrow-feather-and-parquet/28739/28?u=pdeffebach) indicated that there is nothing stopping us in theory from having all code live in Apache Arrow's mono-repo but have the Julia package be a subset...

Very basic prototype of multicol with latex backend

@ronisbr As you know, multicolumn support in PrettyTables.jl is a feature I've wanted for a while. This PR is to add that support for the `:latex` backend. The reason to...

Automatic re-sizing with ByRow in combine

22

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...

Discussion regarding custom row-like outputs in `combine` and `transform`

24

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`,...
