Accessibility in dense tables: screen readers and keyboard paths

ARIA grid roles, focus order, and pragmatic limits when virtualizing tens of thousands of rows.

公開日 2025年3月21日 · Table

Data grids expose rows and cells to assistive tech via role="grid" patterns. Virtualization complicates linear navigation, products should preserve logical tab order and announce sort/filter state changes.

Goals

  • Every interactive cell reachable by keyboard.
  • Visible focus rings on custom cell editors.
  • Document known limitations for mega-grids in VPATs.
