Grouping in table

[cdecinkoKnight]

I saw discussions of a table grouping feature during Quasar v1 days but no mention for v2. Has anyone come up with a workable solution for grouping results in a single table, like sub categories or such? Below the column header row, show a full wide row with "Company A" and then result rows below. Then a full wide row for "Company B" followed by those results.
