Definition The accessible name of a data table % be different from its accessible description.
Purpose
  • Accessible name and description are designed to provide two different types of information to users of assistive technologies and therefore should not duplicate each other.
  • Accessible name is designed to provide a short title to identify the data table, so when users of assistive technology are using table navigation commands they can identify the table.
  • Accessible description is designed to provide a longer summary of the table, this could include author intended conclusions of the data.
Mappings
  • HTML5 and ARIA Techniques (Required)

Techniques
  • Accessible name is typically defined using the caption element, but the summary, title, aria-label and aria-labelledby attribute can also be used.
  • Accessible description is typically defined using the summary attribute, but the title and aria-describedby attribute can also be used.
  • The accessible name is defined before the accessible description, so if using the summary and/or title attribute for the accessible name will require a different technique to add an accessible description.
Manual Checks
  • Verify the accessible name clearly identifies the table.
  • Verify the summary accurately summarizes the table.
