Vue导出el-table表格为Excel文件的两种方式

import * as XLSX from 'xlsx';

// 创建一个新的工作簿
const book = XLSX.utils.book_new();

// 将 HTML 表格转换为工作表
const sheet = XLSX.utils.table_to_sheet(this.$refs.exportTableRef.$el);

// 将工作表添加到工作簿
XLSX.utils.book_append_sheet(book, sheet, "Sheet1");

// 导出工作簿为 Excel 文件
XLSX.writeFile(book, "xxx统计.xlsx");
