Goal

  • Give users access to tables that are exploitable by their user agents and that can be reproduced in a way that will always be understandable.
  • Improve the accessibility of content for people with disabilities.

Implementation

Systematically use the table element and the associated elements tr, td, th, caption, to tag data tables, and not artifices based on accumulations of non-breaking spaces or graphic characters such as pipes (vertical lines "|").
