React 导出 CSV / Excel

装载 vtExport() 后调用 ref 上的 exportCsv() / exportExcel() 导出数据,scope: 'selection' 可仅导出当前框选区域,exportValue 可自定义列导出值。CSV 带 UTF-8 BOM,Excel 为 HTML 表格。

使用的 API

tsx
import { VirtTableReact, vtExport, vtCellSelection } from '@virt-table/react';

// scope: 'selection' 依赖框选,所以两个插件要一起装
const plugins = React.useMemo(() => [vtCellSelection(), vtExport()], []);

// 实例方法(ref 上调用)
tableRef.current?.exportCsv({ filename: '全表.csv' });
tableRef.current?.exportExcel({ filename: '全表.xls' });
tableRef.current?.exportCsv({ filename: '选区.csv', scope: 'selection' });

示例

const list: Row[] = Array.from({ length: 500 }, (_, i) => ({
  id: i + 1,
  name: faker.person.fullName(),
  email: faker.internet.email(),
  city: faker.location.city(),
  score: faker.number.int({ min: 0, max: 100 }),
