Data Tables

  • Introduction
  • Use table markup for data: Structural integrity requires that tags be used appropriately. Avoid using tables for layout; use tables to mark up tabular information.
  • Simplify data table layouts: Complex data tables can be challenging to navigate for both visual and nonvisual users. Present tabular information in its simplest form for easier scanning and screen reader access.
  • Identify data table row and column headings: Table headings are essential for establishing context for the data contained within the rows and columns of a table. Code tables so row and column headings are explicitly tied to the data they describe.
  • Use CAPTION and SUMMARY to describe data tables: Provide additional context by using CAPTION and SUMMARY tags to tie descriptive information about data tables to the tables they describe.
