accessibility:
  keyboard_support:
    - "Tab navigation through interactive elements"
    - "Arrow keys for cell navigation"
    - "Enter/Space for cell activation"
    - "Sorting activation through keyboard"
  screen_reader:

usage_guidelines:
  when_to_use:
    - "For displaying structured data with multiple attributes"

    - "For large datasets that benefit from sorting and filtering"
    - "When precise data layout is important"
  when_not_to_use:
    - "For simple lists (use list components instead)"
    - "For unstructured content (use cards or other layouts)"
    - "When data doesn't fit tabular format well"
  best_practices:
    - "Use clear, descriptive column headers"
    - "Implement sorting for data comparison"
    - "Provide loading states for async data"
    - "Support keyboard navigation throughout"
    - "Consider responsive behavior for mobile"
