Logical Table Structure

Tables can be challenging to read for users and screen readers. Creating logical table structure can facilitate this.

  • Tables should be used to present tabular data and not used for layout purposes.
  • Use proper table heading markup for the header row.
  • Keep tables simple and compact. Avoid using complex row and column spans.
  • You can provide a caption as the table title.
  • Use table "summary" attribute to provide a brief summary of the table.
