tables should not have the same summary and caption

Markup for data tables can be tedious and complex. Make sure the summary table’s properties and the caption don’t match. There are several capabilities in screen readers that help with table navigation, but for these features to function properly, the tables must be accurately marked up.

Tables are announced in a certain way by screen readers. The potential for unclear or erroneous screen reader output exists when tables are not properly marked up.

Screen reader users may become perplexed and struggle to understand the name and function of the table if the summary and caption text for the table are identical.
