Data or header cells should not be used to give caption to a data table

Data table markup can be tedious and confusing. Screen readers have some features to ease table navigation, but tables must be marked up accurately for these features to work correctly. Some tables use cells with a colspan element to visually indicate a caption, instead of using an actual caption element.

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 are not marked up with an actual caption element instead of using a colspan element on cells to visually indicate a caption, screen reader users cannot correctly perceive the purpose of the table visually.
