Description

I was wondering whether we could consider adding the minimal placeholders to implement the Tables interface here. In particular:

istable
rowaccess
columnaccess
rows
columns
schema
Schema

The idea is that this way it is possible to be a Table "source" without depending on Tables. For example, I would like StructArrays to keep being a Tables source but there were concerns both on having it depend on Tables and on using Requires, which is the current solution.

This still makes it harder to be a Table sink without depending on Tables but that would be weird: one should not have a default fallback that depends on a package that maybe was not loaded.

Research direction

Start by inspecting the package's existing API definitions and tests, then compare the requested names with the Tables interface described in the issue. Confirm which placeholders and exports are missing. Done means the listed names are available for defining a Tables source without requiring the Tables package, with tests covering the exposed interface.
