Thank you for opening a Pull Request! Before submitting your PR, there are a few things you can do to make sure it goes smoothly:

  • Make sure to open an issue as a bug/issue before writing your code! That way we can discuss the change, evaluate designs, and agree on the general idea
  • Ensure the tests and linter pass
  • Code coverage does not decrease (if any source code was changed)
  • Appropriate docs were updated (if necessary)

Not ready yet. Initial version works, but needs tweaking (unit tests fail, and dependence on column order is not great).

docs failure is because the pandas docs are currently down.

WARNING: failed to reach any of the inventories with the following issues:

e2e failure appears to be a networking problem for remote functions:

Thanks, @shuoweil ! FYI: I filed sphinx-doc/sphinx#14341 to investigate why the suppress_warnings configuration wasn't working as documented.
