The short answer: build an interactive data table with semantic HTML (<table>, <thead>, <th scope="col">), add ARIA attributes (aria-sort, aria-live, aria-controls), and wire up keyboard handlers that enable sorting, filtering, and cell-by-cell navigation without a mouse. Done right, the result satisfies WCAG 2.2
Level AA, works for sighted users, screen reader users, and keyboard-only users, and needs no framework dependencies
.
This guide walks through the markup, the ARIA attributes, the JavaScript event handlers, and the performance trade-offs you hit once your dataset gets large. The reference patterns come from the WAI-ARIA Authoring Practices Guide sortable table example and the grid pattern .
