xlsx用来处理要导出的数据一般常用的就是json_to_sheet()和table_to_sheet()
json_to_sheet用来处理后台返回的json数据格式
table_to_sheet用来处理页面中的table表格
xlsx-style用来设置导出表格的样式 上下左右居中、颜色、字体大小、表格的边框…
下载 xlsx xlsx-style
npm install xlsx xlsx-style
引入
// 源码什么的都不需要改动import XLSX from 'xlsx';import XLSXStyle from 'xlsx-style';
在vue页面中调用
import {createWs, sheet2blob, openDownloadDialog } from "../../utils/exportExcel"const titles = {landNumber: '宗地号',name: '姓名',xiangName: '乡名称',cunName: '村名称',createTime: '档案上传日期',qlrSignTime: '权利人签署日期',typeList: '驳回原因'}const fields = ['landNumber', 'name', 'xiangName', 'cunName', 'createTime', 'qlrSignTime', 'typeList']const ws = createWs(this.excelData, // 后台返回的json数据fields,titles)openDownloadDialog(sheet2blob(ws), '权利人分析.xlsx');
配置表格的方法(创建的js文件)
export function createWs(data, fields, titles) {const ws = XLSX.utils.json_to_sheet(data, {header: fields,});/*const = merges: [// 合并所需的单元格 我这个导出中没有用到 就没用 视业务而定{ s: { r: 0, c: 2 }, e: { r: 0, c: 5 } },{ s: { r: 0, c: 0 }, e: { r: 1, c: 0 } },{ s: { r: 0, c: 1 }, e: { r: 1, c: 1 } },{ s: { r: 0, c: 6 }, e: { r: 1, c: 6 } },{ s: { r: 0, c: 7 }, e: { r: 1, c: 7 } },{ s: { r: 0, c: 8 }, e: { r: 1, c: 8 } },{ s: { r: 0, c: 9 }, e: { r: 1, c: 9 } },{ s: { r: 0, c: 10 }, e: { r: 1, c: 10 } },{ s: { r: 0, c: 11 }, e: { r: 1, c: 11 } },{ s: { r: 0, c: 12 }, e: { r: 1, c: 12 } },{ s: { r: 0, c: 13 }, e: { r: 1, c: 13 } },{ s: { r: 0, c: 14 }, e: { r: 1, c: 14 } },{ s: { r: 0, c: 15 }, e: { r: 1, c: 15 } },{ s: { r: 0, c: 16 }, e: { r: 1, c: 16 } },{ s: { r: 0, c: 17 }, e: { r: 1, c: 17 } },],ws['!merges'] = merges;*/ws['!cols'] = [ //设置表格的宽度{wpx: 150,},{wpx: 100,},{wpx: 100,},{wpx: 150,},{wpx: 150,},{wpx: 150,},{wpx: 200,},];const range = XLSX.utils.decode_range(ws['!ref']);// 设置表格样式for (let i = range.s.c; i < range.e.c + 1; i++) {for (let j = range.s.r; j < range.e.r + 1; j++) {let cell_address = {c: i,r: j,};let column = XLSX.utils.encode_cell(cell_address);ws[column].s = {font: {name: '宋体',sz: 11,color: {auto: 1,},},border: {color: {auto: 1,},top: {style: 'thin',},bottom: {style: 'thin',},left: {style: 'thin',},right: {style: 'thin',},},alignment: {/// 自动换行wrapText: 1,// 居中horizontal: 'center',vertical: 'center',indent: 0,},};}}//设置中文标题 因为后台返回的数据中属性只能以英文返回 所以需要转化为中文for (let c = range.s.c; c <= range.e.c; c++) {const header = XLSX.utils.encode_col(c) + '1';ws[header].v = titles[ws[header].v];}return ws;}
下面是下载的方法 直接粘过去即可用(创建的js文件)
无论用xlsx还是xlsx-style都可以设置样式但下载一定要用xlsx-style里面的write()方法，只有这样导出的excel表格样式才会生效
// 将一个sheet转成最终的excel文件的blob对象，然后利用URL.createObjectURL下载export function sheet2blob(sheet, sheetName) {sheetName = sheetName || 'sheet1';var workbook = {SheetNames: [sheetName],Sheets: {},};workbook.Sheets[sheetName] = sheet; // 生成excel的配置项// 下载这里一定要用 xlsx-style 的write() 方法才可以使导出excel表格带样式var wbout = XLSXStyle.write(workbook, {type: 'buffer' });var blob = new Blob([wbout], {type: 'application/octet-stream',}); // 字符串转ArrayBufferreturn blob;}export function openDownloadDialog(url, saveName) {if (typeof url == 'object' && url instanceof Blob) {url = URL.createObjectURL(url); // 创建blob地址}var aLink = document.createElement('a');aLink.href = url;aLink.download = saveName || ''; // HTML5新增的属性，指定保存文件名，可以不要后缀，注意，file:///模式下不会生效var event;if (window.MouseEvent) event = new MouseEvent('click');else {event = document.createEvent('MouseEvents');event.initMouseEvent('click',true,false,window,0,0,0,0,0,false,false,false,false,0,null);}aLink.dispatchEvent(event);}
