Web tables represent and organize data within web pages. They should not be used to enhance web content.
Web audiences using assistive technologies can comprehensibly access data from tables if these tables are designed accessibly. A screen reader reads each cell of the table out loud, left to right and top to bottom. Accessible markup is necessary to ensure that the assistive technology user can obtain accurate data.
Best Practices For Tables
- Plan the contents of the table.
- Use a title (caption) for the table.
- Use descriptive and concise row and column heading labels.
- Use each table cell to relay only one piece of information or data.
- Do not merge cell contents.
- Use a simple layout.
- Do not use tables as a substitute for web content.
