时间紧任务重推荐第一种,直接把表格整个拿过来;第二种根据表格的配置和数据进行设置
1、html下载,原生JS
- downTable(name) {
- const uri = 'data:application/vnd.ms-excel;base64,',
- template = '<html xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns="http://www.w3.org/TR/REC-html40"><head></head><body><table>{table}</table></body></html>',
- base64 = function (s) {
- return window.btoa(unescape(encodeURIComponent(s)))
- },
- format = function (s, c) {
- return s.replace(/{(\w+)}/g,
- function (m, p) {
- return c[p];
- })
- }
- //el-table表格设置列浮动,会多出一个隐藏table,需要过滤掉
- const table = document.getElementById('table')?.innerHTML.replace(/[\s\S]*?<\/div>/img, "");
- const ctx = {worksheet: name || 'Worksheet', table}
-
- // 通过创建a标签实现
- const link = document.createElement("a");
- link.href = uri + base64(format(template, ctx));
- // 对下载的文件命名
- link.download = name + '.xlsx';
- link.click();
- }
复制代码
优点:快
缺点:时间会被转义,样式会受页面CSS影响
2、XLSX
- async downTable(type: number) {
- let tableColumn: any[] = [], tableData: any[] = [], fileName = '';
- if (type === 1) {
- tableColumn = this.trendSaleColumn;
- tableData = this.trendSaleData;
- fileName = '售前介入趋势(销售).xlsx';
- }else if (type === 3) {
- await this.getPreSalesConvertInfo(this.transferSaleType, 1);
- tableColumn = this.transferSaleColumn;
- tableData = this.transferSaleData;
- fileName = '售前部门转化(销售).xlsx';
- }
- let data: any[] = [[]];
- tableColumn.forEach((item: any) => {
- data[0].push(item.label);
- })
- tableData.forEach((item: any) => {
- let row: any[] = [];
- tableColumn.forEach((column: any) => {
- row.push(item[column.prop]);
- })
- data.push(row);
- })
- const sheet = XLSX.utils.aoa_to_sheet(data);<br> //合并单元格配置,需要计算需要合并的行列数
- if (type === 3 || type === 4) {
- if (this.productType[1] > 0 && this.productType[2] > 0) {
- sheet['!merges'] = [
- {s: {r: 1, c: 0}, e: {r: this.productType[1], c: 0}},//s表示开始,e表示结束,r表示行,c表示列;
- {s: {r: this.productType[1] + 1, c: 0}, e: {r: this.productType[2], c: 0}}
- ];
- } else if (this.productType[1] > 0 || this.productType[2] > 0) {
- sheet['!merges'] = [
- {s: {r: 1, c: 0}, e: {r: this.productType[1] || this.productType[2], c: 0}},//s表示开始,e表示结束,r表示行,c表示列;
- ];
- }
- }
- // 通过创建a标签实现
- const link = document.createElement("a");
- link.href = URL.createObjectURL(sheet2blob(sheet));
- // 对下载的文件命名
- link.download = fileName;
- link.click();
- }
复制代码- sheet2blob(sheet: any, sheetName: string = 'sheet1') {
- const workbook: any = {
- SheetNames: [sheetName],
- Sheets: {}
- };
- workbook.Sheets[sheetName] = sheet;
- // 生成excel的配置项
- const wopts: any = {
- bookType: 'xlsx', // 要生成的文件类型
- bookSST: false, // 是否生成Shared String Table,官方解释是,如果开启生成速度会下降,但在低版本IOS设备上有更好的兼容性
- type: 'binary'
- };
- const wbout = XLSX.write(workbook, wopts);
- const blob = new Blob([s2ab(wbout)], {type: "application/octet-stream"});
- // 字符串转ArrayBuffer
- function s2ab(s: any) {
- const buf = new ArrayBuffer(s.length);
- const view = new Uint8Array(buf);
- for (let i = 0; i != s.length; ++i) view[i] = s.charCodeAt(i) & 0xFF;
- return buf;
- }
- return blob;
- }
复制代码
优点:单元格内容可控,可以设置单元合并等XLSX支持的配置
缺点:复杂表格需要计算合并单元格的位置和数量,比如多级表头
