Data table markup can be tedious and confusing. It is important to make sure caption and summary table attributes are not identical. Screen readers have a number of features to make table navigation easier, but tables must be marked up accurately for these features to work properly.
The Algorithm, in Simple Terms
Checks that data tables that have both a summary and caption have the same text for each.
Why this is Important
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.
How to Fix the Problem
Ensure the summary and caption text are different from each other.
