# Data table with caption but no th - Screen Reader Reliability Testing

This page was inspired by the Data table with caption but no th page.

The following table is an example of a common accessibility issue with tables. In this table the th element is not used to indicate that a table cell should be interpreted as a header cell instead of a data cell; instead the td element is used and text style is used to visually indicate that the cell should be interpreted as a header style.

For information on why this is an accessibility issue see F91: Failure of Success Criterion 1.3.1 for not correctly marking up table headers.
