Keep tables as simple as possible. Tables that contain lists, merged cells, or other tables are considered to be complicated tables, and screen readers have a difficult time parsing and navigating the table contents.

Follow these guidelines when including tables in your documentation:

• If you need to leave a table cell blank, add a nonbreaking space to the cell instead of leaving it empty.
• Avoid merging or splitting table cells. If your table is becoming overly complex, consider using a separate table or a different type of formatting to organize the additional information.
• Don't use X or another character to indicate compatibility or support. Instead, use Yes and No. See Writing with accessibility for more information about using text instead of symbols in your documentation.
