Address grid component comments.

[michelle192837]

Followup to comments on #1192 . (Some already addressed by #1207).

For row-id vs. row-name, I realized that given how the component renders, it's less of an ID and more of a display name thing, so I think 'name' feels more accurate? Happy to roll that part back though.
