Accessible Tables and Semantic Data Accessibility

Tables and data displays should communicate structure clearly, remain readable at different zoom levels, and support keyboard and assistive technology navigation.

Read table guidanceLearn how to create accessible tables that meet WCAG and Section 508 requirements.

Readable Structure

  • Use clear headers, spacing, and consistent alignment.
  • Avoid overly dense tables that require excessive scanning.

Accessibility Checks

  • Ensure keyboard navigation works logically across rows and columns.
  • Use semantic table markup with properly associated headers.

Quick Wins

  • Keep labels concise and easy to scan.
  • Use color as support — not the only way information is conveyed.
