No it wouldn't, as - if I understand the original issue correctly - this
would still fail 1.4.1 Use of Color, because that's a visual SC and
having aria-anything there would not help sighted non-screen-reader
users, which is the point of the SC. At a stretch, it likely would pass
1.1.1 Non-text Content, but that's not enough. For 1.4.1 you really want
some other visible indication that doesn't rely on colour alone (e.g. a
thicker border around the cell or similar).

That's why I suggested a heading. If a heading wrapping around a data cell fails WCAG, and not all assistive technology users have the functionality of “quick keys” like screen readers offer, then what could work to solve the problem Geethavani.Shamanna poses?

A basic skip link before the table, which would also help
non-screen-reader keyboard users? It can hidden at first but appear on
focus, and allow to jump straight to the cell?

Agree that it would be a bit of a perversion of structural markup if you
added a heading there.
