How to fix empty table header on Webflow

Steps for Webflow

1. Open your project in the Webflow Designer. Select the Table element on the canvas that contains the empty header.
2. Click the empty `<th>` cell in the Designer. In the right-hand panel, type the column label text directly into the cell on the canvas.
3. If the header must remain visually blank (e.g., a spacer), open the element's Settings panel (the gear icon) and add an `aria-label` attribute under the Custom Attributes section — set Name to `aria-label` and Value to the descriptive label (e.g., `Thumbnail`).
4. Also add a `scope` custom attribute with value `col` or `row` as appropriate.
5. Publish your changes and re-test with the WAVE or axe DevTools browser extension on the live site.

<th scope="col">Price (USD)</th>

<!-- Visually hidden label for a decorative/spacer corner cell -->
<th scope="col" aria-label="Product thumbnail"></th>

<!-- Icon-only header with aria-label -->
<th scope="col" aria-label="Add to cart"></th>

What is empty table header?

A table header cell (`<th>`) is the label that sits at the top of a column or the start of a row in an HTML table — it tells everyone what kind of data that column or row contains (e.g., "Product Name," "Price," "Quantity"). An "empty table header" means one or more of those label cells exists in your page's code but contains no readable text. The cell may look fine visually (perhaps it's a decorative spacer or uses an icon), but it has nothing for a screen reader to announce. Screen readers rely on header text to describe a table's structure, so when a header is blank, users who are blind or have low vision lose the context they need to understand the data.

**Accessibility & legal risk:** Empty table headers violate WCAG 2.1 Success Criterion 1.3.1 (Info and Relationships), which is the benchmark used in accessibility lawsuits and regulatory audits (ADA, EN 301 549, EAA 2025). A single empty header in a product-comparison or pricing table can make that entire table unusable for customers who rely on assistive technology — costing you sales and exposing you to legal liability. **SEO:** Search engines also use table structure to understand tabular content; properly labelled headers improve the semantic clarity of your pages, which can contribute to better crawlability and richer structured understanding of your data. **Conversions:** Accessible, well-labelled product or size tables are easier for all customers to scan, reducing the friction that causes shoppers to abandon a purchase.
