        'The DataTable component demonstrates strong compliance with WCAG 2.1 Level AA standards. The component implements comprehensive keyboard navigation, proper ARIA attributes for grid role, screen reader support, focus management, and accessible filtering and pagination controls. The table uses role="grid" with appropriate aria-rowcount and aria-colcount attributes. Keyboard navigation includes arrow keys, Tab, Enter, Space, Home, End, PageUp, and PageDown. Filter icons and column headers are keyboard accessible. Pagination controls support full keyboard navigation. Some contrast ratios and touch target sizes may require verification depending on implementation context.',
