vue中使用Luckysheet实现Excel的导入 编辑 导出等功能

一、准备阶段

1、在pubilic文件夹下的index.html文件中的head标签中引入Luckysheet的cdn文件

<link rel='stylesheet' href='/npm/luckysheet@latest/dist/plugins/css/pluginsCss.css' /><link rel='stylesheet' href='/npm/luckysheet@latest/dist/plugins/plugins.css' /><link rel='stylesheet' href='/npm/luckysheet@latest/dist/css/luckysheet.css' /><link rel='stylesheet' href='/npm/luckysheet@latest/dist/assets/iconfont/iconfont.css' /><script src="/npm/luckysheet@latest/dist/plugins/js/plugin.js"></script><script src="/npm/luckysheet@latest/dist/luckysheet.umd.js"></script>

2、安装三个依赖（exceljs和 file-saver用来导出，luckyexcel用来处理导入数据 ）

npm i -S exceljs file-saver luckyexcel

3、创建一个js文件export.js

import FileSaver from 'file-saver'const Excel = require('exceljs')var setMerge = function (luckyMerge = {}, worksheet) {const mergearr = Object.values(luckyMerge)mergearr.forEach(function (elem) {// elem格式：{r: 0, c: 0, rs: 1, cs: 2}// 按开始行，开始列，结束行，结束列合并（相当于 K10:M12）worksheet.mergeCells(elem.r + 1,elem.c + 1,elem.r + elem.rs,elem.c + elem.cs)})}var setBorder = function (luckyBorderInfo, worksheet) {if (!Array.isArray(luckyBorderInfo)) return// console.log('luckyBorderInfo', luckyBorderInfo)luckyBorderInfo.forEach(function (elem) {// 现在只兼容到borderType 为range的情况// console.log('ele', elem)if (elem.rangeType === 'range') {const border = borderConvert(elem.borderType, elem.style, elem.color)const rang = elem.range[0]// console.log('range', rang)const row = rang.rowconst column = rang.columnfor (let i = row[0] + 1; i < row[1] + 2; i++) {for (let y = column[0] + 1; y < column[1] + 2; y++) {worksheet.getCell(i, y).border = border}}}if (elem.rangeType === 'cell') {// col_index: 2// row_index: 1// b: {// color: '#d0d4e3'// style: 1// }const {colIndex, rowIndex } = elem.valueconst borderData = Object.assign({}, elem.value)delete borderData.col_indexdelete borderData.row_indexconst border = addborderToCell(borderData, rowIndex, colIndex)// console.log('bordre', border, borderData)worksheet.getCell(rowIndex + 1, colIndex + 1).border = border}// console.log(rang.column_focus + 1, rang.row_focus + 1)// worksheet.getCell(rang.row_focus + 1, rang.column_focus + 1).border = border})}var setStyleAndValue = function (cellArr, worksheet) {if (!Array.isArray(cellArr)) returncellArr.forEach(function (row, rowid) {row.every(function (cell, columnid) {if (!cell) return trueconst fill = fillConvert(cell.bg)const font = fontConvert(cell.ff,cell.fc,cell.bl,cell.it,cell.fs,cell.cl,cell.ul)const alignment = alignmentConvert(cell.vt, cell.ht, cell.tb, cell.tr)let value = ''if (cell.f) {value = {formula: cell.f, result: cell.v }} else if (!cell.v && cell.ct && cell.ct.s) {// xls转为xlsx之后，内部存在不同的格式，都会进到富文本里，即值不存在与cell.v，而是存在于cell.ct.s之后// value = cell.ct.s[0].vcell.ct.s.forEach(arr => {value += arr.v})} else {value = cell.v}// style 填入到_value中可以实现填充色const letter = createCellPos(columnid)const target = worksheet.getCell(letter + (rowid + 1))// console.log('1233', letter + (rowid + 1))for (const key in fill) {target.fill = fillconsole.log(key)break}target.font = fonttarget.alignment = alignmenttarget.value = valuereturn true})})}var setImages = function (imagesArr, worksheet, workbook) {if (typeof imagesArr !== 'object') returnfor (const key in imagesArr) {// console.log(imagesArr[key]);// 通过 base64 将图像添加到工作簿const myBase64Image = imagesArr[key].src// 开始行 开始列 结束行 结束列const start = {col: imagesArr[key].fromCol, row: imagesArr[key].fromRow }const end = {col: imagesArr[key].toCol, row: imagesArr[key].toRow }const imageId = workbook.addImage({base64: myBase64Image,extension: 'png'})worksheet.addImage(imageId, {tl: start,br: end,editAs: 'oneCell'})}}var fillConvert = function (bg) {if (!bg) {return {}}// const bgc = bg.replace('#', '')const fill = {type: 'pattern',pattern: 'solid',fgColor: {argb: bg.replace('#', '') }}return fill}var fontConvert = function (ff = 0,fc = '#000000',bl = 0,it = 0,fs = 10,cl = 0,ul = 0) {// luckysheet：ff(样式), fc(颜色), bl(粗体), it(斜体), fs(大小), cl(删除线), ul(下划线)const luckyToExcel = {0: '微软雅黑',1: '宋体（Song）',2: '黑体（ST Heiti）',3: '楷体（ST Kaiti）',4: '仿宋（ST FangSong）',5: '新宋体（ST Song）',6: '华文新魏',7: '华文行楷',8: '华文隶书',9: 'Arial',10: 'Times New Roman ',11: 'Tahoma ',12: 'Verdana',num2bl: function (num) {return num !== 0}}// 出现Bug，导入的时候ff为luckyToExcel的valconst font = {name: typeof ff === 'number' ?

二、创建一个初始Excel表格

0、引入依赖

import LuckyExcel from 'luckyexcel'import {exportExcel } from '@/utils/export'

1、需要一个容器

<!-- luckysheet容器 --><divid="luckysheet"style="margin: 0px; padding: 0px; position: absolute; width: 100%; left: 0px; top: 0px; bottom: 0px; z-index: 0"></div>

2、需要一个配置文件

options: {container: 'luckysheet', //容器id名title: '测试Excel', // 表 头名lang: 'zh', // 中文showtoolbar: true, // 是否显示工具栏showinfobar: false, // 是否显示顶部信息栏showsheetbar: true // 是否显示底部sheet按钮}

3、创建一个空白表格

window.luckysheet.create(this.options)

4、创建带数据的表格

const data = [{name: 'cell',color: '',index: 1,status: 0,order: 1,celldata: [{r: 0, // 行c: 0, // 列v: '姓名' // 值},{r: 1, // 行c: 0, // 列v: '张三' // 值},{r: 2, // 行c: 0, // 列v: '李四' // 值},{r: 3, // 行c: 0, // 列v: '王五' // 值},{r: 0,c: 1,v: '年龄'},{r: 1,c: 1,v: '1'},{r: 2,c: 1,v: '2'},{r: 3,c: 1,v: '3'}],config: {}},{name: 'Sheet2',color: '',index: 1,status: 0,order: 1,celldata: [],config: {}},{name: 'Sheet3',color: '',index: 2,status: 0,order: 2,celldata: [],config: {}}]window.luckysheet.destroy()this.options.data = datawindow.luckysheet.create(this.options)}

三、导入本地Excel创建

只需要拿到files数据源传入即可

LuckyExcel.transformExcelToLucky(files, (exportJson, luckysheetfile) => {if (exportJson.sheets === null || exportJson.sheets.length === 0) {this.$message.error('无法读取excel文件的内容，当前不支持xls文件！')return}window.luckysheet.destroy()this.options.data = exportJson.sheetsconsole.log('数据', this.options.data)window.luckysheet.create(this.options)})

四、导出

exportExcel(window.luckysheet.getAllSheets(), this.name)

五、git地址

/Aseoe/ant-design-vue-pro
