Re: Table Headers In Separate Table From Data

When I've done the two-tables thing, IF I don't need the headers clickable for sorting or select-column or whatnot, then I make the visible table-with-only headers the aria-hidden one. Screen reader users then at least get 1 full single table, and the headers on it are simply covered up by the aria-hidden table showing headers.

Where I have trouble is when I need click events and key listeners on those headers.

cheers,
