How to Fix the Problem

Ensure that layout tables, e.g. tables used only to visually lay out elements within the content, are not using summary attributes.

The Algorithm, in Simple Terms

Engine scans the page for <table> elements with non-empty summary attribute but using role presentation or containing no header cells (th elements or elements with role columnheader / rowheader).

Why Is it Important?

In layout tables the summary attribute will distract users navigating the content via a screen reader.

Code Example

<table summary="Monthly savings for the Flintstones family">
