Free Table Accessibility Checker
Scan your data tables for missing headers, captions, and proper markup. Make sure screen reader users can understand your tabular data.
How Our Table Accessibility Checker Works
Our table checker evaluates every table on your page for proper accessible markup. It detects tables used for layout purposes, data tables missing header cells, headers without scope attributes, tables without captions or summaries, complex tables that need headers attributes for cell-to-header association, and empty table cells that should have content or be marked as presentational.
The Impact of Table Accessibility Checker Issues
Data tables are one of the most difficult content types for screen reader users to navigate. Without proper headers, a screen reader user hears a stream of disconnected values with no way to understand which column or row they belong to. Properly marked-up tables let screen readers announce the header for each cell as the user navigates, making complex data understandable.
Issues Our Table Accessibility Checker Finds
-
Missing table headers
Data tables using <td> elements for headers instead of <th>. Screen readers cannot identify column or row headers without proper <th> elements.
-
No scope attribute
Header cells (<th>) without scope="col" or scope="row" to indicate whether they label a column or a row.
-
Missing caption
Tables without a <caption> element that describes the table's purpose. Screen readers use captions to help users decide whether to explore the table.
-
Layout tables with headers
Tables used for visual layout that incorrectly include <th> elements or summary attributes, confusing screen readers into treating them as data tables.

Frequently Asked Questions
How do I make a data table accessible?
Use <th> elements for header cells with scope="col" or scope="row", add a <caption> that describes the table, and for complex tables with multi-level headers, use the headers attribute to associate each data cell with its headers. Avoid using tables for layout.
When should I use tables vs. CSS grid?
Use HTML tables only for tabular data - information that has a logical row and column relationship, like spreadsheets, schedules, or comparison charts. Use CSS Grid or Flexbox for visual layout. Using tables for layout confuses screen readers.
What about responsive tables?
Responsive tables that reflow on mobile must maintain their accessible markup. If you transform a table into a card layout on small screens, ensure each value is still programmatically associated with its header using techniques like data-label attributes or aria-label.
