The <caption> element should not contain the same text as the summary attribute

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.

When tables have summary and caption text that is identical, screen reader users can be confused and find it difficult to know the name and purpose of the table.

Fixing the problem

This Rule checks for tables that have identical summary and caption text. To fix the problem, ensure that the content of the summary attribute and the <caption> elements are not identical.

To ensure screen reader users can make sense of tabular data:

1. Use the <caption> element for onscreen title.
2. Use the summary attribute—only read by screen readers—to describe the table structure.
