When following the Tabular Classification tutorial, I encountered the following error: UndefVarError: getcoltypes not defined.

The reason is that these symbols are not exported in "Tabular.jl" and thus not exported by FastAI through @reexport using .Tabular.

I can make a PR. However, I am not clear about your original intention. Do you want FastAI.getcoltypes or Tabular.getcoltypes? The latter works now without changing the source code.
