## Which issue does this PR close? Part of https://github.com/apache/datafusion/issues/4028 ## Rationale for this change While working with @itsjunetime on https://github.com/apache/datafusion/pull/12135 I noticed that the description / documentation of `PhysicalExpr` was not as clear as it could be: 1. It didn't really talk about the use of column indexes vs names 2. The trait itself was not well documented 3. The `Column` epr was also not as well documented as it could be ## What changes are included in this PR? Improve the documentation so this is clearer ## Are these changes tested?
