Link table cells to headers using IDs

In complex tables with multi-level headers, explicit header-to-cell linking ensures screen readers accurately announce the relationship between data and its context.

Quick Reference

• Use the headers attribute for complex tables where scope isn't enough
• Ensure the headers attribute references valid id values of <th> elements
• Separate multiple header IDs with spaces

Check

Verify that td headers attributes reference valid and existing th IDs.

Fix

Correct the headers attribute to reference the appropriate th IDs.

Explain

Explain when to use the headers attribute instead of scope for complex table structures.

Code Review

Review the rendered markup and interactive states that affect Link table cells to headers using IDs. 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.
