Tables Missing Header Cells

What This Means

One or more data tables in the page have no <th> header cells. The table is built entirely of <td> cells with no row or column headers declared.

Why It Matters for SEO

Screen readers read tables by announcing the header of each cell as they traverse the table. Without <th> elements, the screen reader cannot identify what each column or row represents — it reads only raw cell values with no context. This is a WCAG 2.1 issue (Success Criterion 1.3.1).

For search engines, <th> elements provide additional semantic context about the tabular data. A table about pricing with <th> headers (Plan, Price, Features) is more interpretable than a table of raw <td> values.

What the Platform Checks

The platform inspects all <table> elements and checks for the presence of at least one <th> element within. Fires when a table is found with no <th> cells.

How to Fix It

• Add <th> elements for column headers in the first row (inside <thead>).
• Add <th scope="col"> for column headers and <th scope="row"> for row headers.
• For complex tables with both row and column headers: use the scope attribute correctly.
• If you are using tables for layout rather than data: consider switching to CSS Grid or Flexbox, which is more appropriate for layout and does not require header semantics.
