将表格数据导出 Excel 格式的数据方法（2）

1、在工具类中创建一个脚本文件

/*** @param {*} tableValueData*      表格数据: []* @param {*} tableTitleData*      表格标题数据: ["", "", "", ""]* @param {*} fileName*      文件名* @param {*} tableHeader*      表格名*/// 引入插件
import XLSXS from "xlsx-js-style";
// 暴露方法
export function exportExcel(tableValueData, tableTitleData, fileName, tableHeader) {const header = [];const body = [];let strMaxNum = {};tableValueData.forEach((e, i) => {let styleArr = [];e.forEach((ele, ei) => {if (!ele) ele = 0;let styleObj = {v: ele,t: "s",s: {alignment: {vertical: "center",horizontal: "center",},border: {top: { style: "thin" },left: { style: "thin" },bottom: { style: "thin" },right: { style: "thin" },},},};styleArr.push(styleObj);strMaxNum[ei] = strMaxNum[ei]? strMaxNum[ei] > ele.toString().length? strMaxNum[ei]: ele.toString().length: ele.toString().length;});body.push(styleArr);});let cols = [];let title1 = [];tableTitleData.forEach((item, index) => {let obj = {v: item,t: "s",s: {alignment: {vertical: "center",horizontal: "center",},border: {top: { style: "thin" },left: { style: "thin" },bottom: { style: "thin" },right: { style: "thin" },},},};title1.push(obj);let resultMaxNum = Number(item.length) > strMaxNum[index] ? Number(item.length) : strMaxNum[index];let colsObj = { wch: resultMaxNum * 2 + 5 };cols.push(colsObj);// 设置标题if (index == 0) {header.push({v: tableHeader,t: "s",s: {font: {bold: true,sz: 14,name: "宋体",},alignment: {vertical: "center",horizontal: "center",},border: {top: { style: "thin" },left: { style: "thin" },bottom: { style: "thin" },right: { style: "thin" },},},});} else {header.push({v: '',t: "s",s: {font: {bold: true,sz: 14,name: "宋体",},alignment: {vertical: "center",horizontal: "center",},border: {top: { style: "thin" },left: { style: "thin" },bottom: { style: "thin" },right: { style: "thin" },},},});}});body.unshift(title1);body.unshift(header);const sheet = XLSXS.utils.aoa_to_sheet(body);sheet["!cols"] = cols;const rows = [{ hpx: 20 }, { hpx: 16 }, { hpx: 18 }];sheet["!rows"] = rows;let mergeNum = tableTitleData.length - 1;const merges = [{ s: { r: 0, c: 0 }, e: { r: 0, c: mergeNum } }];sheet["!merges"] = merges; // 将merges添加到sheet中// 导出Excel文件const workbook = XLSXS.utils.book_new(); // 创建虚拟的 workbookXLSXS.utils.book_append_sheet(workbook, sheet, tableHeader); // 向 workbook 中添加 sheetXLSXS.writeFile(workbook, `${fileName}.xlsx`); // 导出 workbook
