| 59 | ```tsx |
| 60 | // Modern React component with performance optimization |
| 61 | import React, { memo, useCallback, useMemo } from 'react'; |
| 62 | import { useVirtualizer } from '@tanstack/react-virtual'; |
| 63 | |
| 64 | interface DataTableProps { |
| 65 | data: Array<Record<string, any>>; |
| 66 | columns: Column[]; |
| 67 | onRowClick?: (row: any) => void; |
| 68 | } |
| 69 | |
| 70 | export const DataTable = memo<DataTableProps>(({ data, columns, onRowClick }) => { |
| 71 | const parentRef = React.useRef<HTMLDivElement>(null); |
| 72 | |
| 73 | const rowVirtualizer = useVirtualizer({ |
| 74 | count: data.length, |
| 75 | getScrollElement: () => parentRef.current, |
| 76 | estimateSize: () => 50, |
| 77 | overscan: 5, |
| 78 | }); |
| 79 | |
| 80 | const handleRowClick = useCallback((row: any) => { |
| 81 | onRowClick?.(row); |
| 82 | }, [onRowClick]); |
| 83 | |
| 84 | return ( |
| 85 | <div |
| 86 | ref={parentRef} |
| 87 | className="h-96 overflow-auto" |
| 88 | role="table" |
| 89 | aria-label="Data table" |
| 90 | > |
| 91 | {rowVirtualizer.getVirtualItems().map((virtualItem) => { |
| 92 | const row = data[virtualItem.index]; |
| 93 | return ( |
| 94 | <div |
| 95 | key={virtualItem.key} |
| 96 | className="flex items-center border-b hover:bg-gray-50 cursor-pointer" |
| 97 | onClick={() => handleRowClick(row)} |
| 98 | role="row" |
| 99 | tabIndex={0} |
| 100 | > |
| 101 | {columns.map((column) => ( |
| 102 | <div key={column.key} className="px-4 py-2 flex-1" role="cell"> |
| 103 | {row[column.key]} |
| 104 | </div> |
