Providing captions for data tables allows users to understand the context and purpose of the information before they begin navigating the data cells.

Objectives

• Enable assistive technologies to easily identify the nature of the information provided in a table.
• Improve content accessibility for people with disabilities.

Implementation

• Include and populate an HTMLelement for every data table.
• If necessary, use aelement that is visually hidden while remaining accessible to assistive technologies.

Control

• Check the HTML source code of the EPUB pages for the presence of aelement for each data table. If this element is visually hidden using a CSS class, ensure it remains accessible to assistive technologies.
