interface DataTableProps {
  data: Array<Record<string, any>>;
  columns: Column[];
  onRowClick?: (row: any) => void;
}

export const DataTable = memo<DataTableProps>(({ data, columns, onRowClick }) => {
  const parentRef = React.useRef<HTMLDivElement>(null);
  
  const rowVirtualizer = useVirtualizer({
    count: data.length,
    getScrollElement: () => parentRef.current,
    estimateSize: () => 50,
    overscan: 5,
  });

  const handleRowClick = useCallback((row: any) => {
    onRowClick?.(row);
  }, [onRowClick]);

  return (
    <div
