I don't know any easy way to do that. We do already have the grouping visible in the first column...
Can we lightly background color every other rowgroup (i.e., "greenbar")?
I don't think having a separate Result column helps. The additional horizontal whitespace distances all relevant context information (at least on a wide monitor). Having the example rows mirror the Signature row seems like an easier to consume choice.
e.g.,
enum_first(null::rainbow) → red
date '2001-09-28' + 7 → 2001-10-05
Its also removes the left alignment in a fixed width column which draws unwanted visual attention.
