Core Mandate

Use tables for information whose meaning depends on relationships between rows and columns. Mark those relationships in HTML so users can identify the table, navigate its cells, and hear the relevant headers with each value. The complexity of the markup should match the complexity of the information — simplifying or splitting a table is often better than adding increasingly complicated header associations.
