前言

导入依赖，具体前端vue配置就不介绍了，直接晒具体细节代码

实现

需要在多table外加div，其他都是基本操作

js代码

import FileSaver from 'file-saver'
import * as XLSX from "xlsx";

const htmlToExcel = {

  getExcelNew(className, excelName) {
    var xlsxParam = {raw: true}; // 导出的内容只做解析，不进行格式转换

    // 创建新的表格元素并插入到DOM中
    var newTable = document.createElement('table');
    newTable.innerHTML = document.querySelector("#table2");
    newTable.innerHTML = document.querySelector("#table3");
    newTable.innerHTML = document.querySelector("#table4");
    newTable.innerHTML = document.querySelector("#table5");
    newTable.innerHTML = document.querySelector("#table6");
    newTable.innerHTML = document.querySelector("#table7");
    document.body.appendChild(newTable);

    let fix = document.querySelector('.el-table__fixed');
    // document.querySelector('.el-picker-panel').innerHTML = "";
    // document.querySelector('.el-picker-panel').parentNode.removeChild(document.querySelector('.el-picker-panel'));
    let wb;
    if (fix) { //判断要导出的节点中是否有fixed的表格，如果有，转换excel时先将该dom移除，然后append回去
      wb = XLSX.utils.table_to_book(document.querySelector(className).removeChild(fix));
      document.querySelector(className).appendChild(fix);
    } else {
      wb = XLSX.utils.table_to_book(document.querySelector("#tableApp"));
    }
    var wbout = XLSX.write(wb, {bookType: 'xlsx', bookSST: true, type: 'array'});

    try {
      FileSaver.saveAs(new Blob([wbout], {type: 'application/octet-stream'}), excelName + ".xlsx")
    } catch (e) {
      if (typeof console !== 'undefined') {
      }
    }
    return wbout
  },

};
export default htmlToExcel;
