How to access another column in a custom check?

[tturnerswdev33]

I figured out how to create and call a custom check function, but I need to check what value is set in another column inside the custom check. So how do I pass a different column into the custom check (or access a different column inside there)?

You can use wide checks, see here: https://pandera.readthedocs.io/en/stable/checks.html#wide-checks

Yes I saw that and will be working on that tomorrow... but I think Pandera would be more intuitive if it could pass a dependency column to a custom check function, then we can write any logic that we need.

I created a custom check and registered it. Then i called that function from the wide check. It seems to pass the entire data frame as an object but I can't figure out how to pick off rows or values once inside there. Any suggestions?
