Screen readers read table data cell-by-cell—without proper headers, users hear meaningless numbers without context. 'Row 3, Column 2: $99' vs just '$99'.
Quick Reference
- Use elements for headers with scope='col' or scope='row'
- Add to describe the table's purpose
- Never use tables for layout—use CSS Grid or Flexbox instead
- Use id/headers for complex tables with merged cells
- For simple tables with a clear adjacent section heading, missing
scopeis often a stronger finding than missing<caption> - Prefer one strong table-semantics finding over multiple weaker enhancements on the same simple table
Check
Verify tables use proper th elements with scope, caption or aria-labelledby, and semantic table structure.
Fix
Add proper table headers with scope attributes, captions for context, and ensure tables are not used for layout.
Explain
Explain how proper table markup helps screen reader users understand data relationships and navigate table content.
Code Review
Review the rendered markup and interactive states that affect Use semantic table markup for screen readers. Flag exact elements, roles, labels, focus behavior, or keyboard interactions that violate the rule, and note how to verify the fix with browser accessibility tooling or assistive tech.
