vue中luckysheet实现导出

本文属于转载

二、使用步骤

1.引入库

代码如下（示例）：

在index.js 中引入静态资源
npm install exceljs
npm install FileSaver

    <link rel='stylesheet' href='https://cdn.jsdelivr.net/npm/luckysheet/dist/plugins/css/pluginsCss.css' /><link rel='stylesheet' href='https://cdn.jsdelivr.net/npm/luckysheet/dist/plugins/plugins.css' /><link rel='stylesheet' href='https://cdn.jsdelivr.net/npm/luckysheet/dist/css/luckysheet.css' /><link rel='stylesheet' href='https://cdn.jsdelivr.net/npm/luckysheet/dist/assets/iconfont/iconfont.css' /><script src="https://cdn.jsdelivr.net/npm/luckysheet/dist/plugins/js/plugin.js"></script><script src="https://cdn.jsdelivr.net/npm/luckysheet/dist/luckysheet.umd.js"></script>

2.vue 组件中初始化表格容器

代码如下（示例）：

<template><div><div style="padding:10px 10px 0 10px"><el-form inline :model="dataForm"><el-button type="primary" plain @click='downloadExcel()'>下载</el-button></el-form-item></el-form></div><div id="luckysheet" style="margin:0px;padding:0px;position:absolute;width:100%;left: 0px;top: 60px;bottom:0px;"></div><div v-show="isMaskShow" style="position: absolute;z-index: 1000000;left: 0px;top: 0px;bottom: 0px;right: 0px; background: rgba(255, 255, 255, 0.8); text-align: center;font-size: 40px;align-items:center;justify-content: center;display:flex;">Downloading</div></div>
</template><script>
import LuckyExcel from 'luckyexcel'
import moment from 'moment'
//外部引入方法
import {exportExcel} from '../../../components/report/export'
export default {data(){return {tableData:[ {"name": "Sheet2","color": "","index": 1,"status": 0,"order": 1,"celldata": [],"config": {}}],isMaskShow: false,}},created () {this.getFormData();},mounted() {this.init() //初始化容器放在mounted中},methods:{init(){let that = this$(function () {luckysheet.create({container: 'luckysheet', // 设定DOM容器的idtitle: 'xx 站信息', // 设定表格名称lang: 'zh', // 设定表格语言plugins:['chart'],showtoolbar:true,data:that.tableData});});},downloadExcel(){let files = luckysheet.getluckysheetfile()console.log('表格数据',files);exportExcel(luckysheet.getAllSheets(),"厂站信息")},}
}
</script>

3.export.js

代码如下（示例）：

    // import { createCellPos } from './translateNumToLetter'
const Excel = require('exceljs')
import FileSaver from 'file-saver'
export var exportExcel = function(luckysheet, value) {// 参数为luckysheet.getluckysheetfile()获取的对象// 1.创建工作簿，可以为工作簿添加属性const workbook = new Excel.Workbook()// 2.创建表格，第二个参数可以配置创建什么样的工作表if (Object.prototype.toString.call(luckysheet) === '[object Object]') {luckysheet = [luckysheet]}luckysheet.forEach(function(table) {if (table.data.length === 0) return  true// ws.getCell('B2').fill = fills.const worksheet = workbook.addWorksheet(table.name)const merge = (table.config && table.config.merge) || {}const borderInfo = (table.config && table.config.borderInfo) || {}// 3.设置单元格合并,设置单元格边框,设置单元格样式,设置值setStyleAndValue(table.data, worksheet)setMerge(merge, worksheet)setBorder(borderInfo, worksheet)return true})// return// 4.写入 bufferconst buffer = workbook.xlsx.writeBuffer().then(data => {// console.log('data', data)const blob = new Blob([data], {type: 'application/vnd.ms-excel;charset=utf-8'})console.log("导出成功！")FileSaver.saveAs(blob, `${value}.xlsx`)})return buffer
}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') {let border = borderConvert(elem.borderType, elem.style, elem.color)let rang = elem.range[0]// console.log('range', rang)let row = rang.rowlet 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 { col_index, row_index } = elem.valueconst borderData = Object.assign({}, elem.value)delete borderData.col_indexdelete borderData.row_indexlet border = addborderToCell(borderData, row_index, col_index)// console.log('bordre', border, borderData)worksheet.getCell(row_index + 1, col_index + 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 truelet fill = fillConvert(cell.bg)let font = fontConvert(cell.ff,cell.fc,cell.bl,cell.it,cell.fs,cell.cl,cell.ul)let 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let letter = createCellPos(columnid)let target = worksheet.getCell(letter + (rowid + 1))// console.log('1233', letter + (rowid + 1))for (const key in fill) {target.fill = fillbreak}target.font = fonttarget.alignment = alignmenttarget.value = valuereturn true})})
}var fillConvert = function(bg) {if (!bg) {return {}}// const bgc = bg.replace('#', '')let 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 ? false : true}}// 出现Bug，导入的时候ff为luckyToExcel的vallet font = {name: typeof ff === 'number' ? luckyToExcel[ff] : ff,family: 1,size: fs,color: { argb: fc.replace('#', '') },bold: luckyToExcel.num2bl(bl),italic: luckyToExcel.num2bl(it),underline: luckyToExcel.num2bl(ul),strike: luckyToExcel.num2bl(cl)}return font
