Table Headers Must Refer to Data Cells


When I run a Page Check I get the following Serious Problem: 

Table headers in a data table must refer to data cells


  • Omni CMS


Omni CMS Final Checks evaluate all code on a page and detect accessibility issues not meeting WCAG 2.0 (Level AA) standards

It detected the page contains a table with header cells that do not coordinate with data cells. This is caused by a table header cell using the wrong scope, such as a row header with the scope of column or vice versa. Screen readers have a specific way of announcing tables. When tables are not properly marked up, this creates the opportunity for confusing or inaccurate screen reader output.


If a table with header cells exists, ensure that they reference elements with text available to screen readers using scope correctly.

  1. Click  Yellow Light Bulb to check out page.
