1.安装依赖
npm install --save xlsx file-saver
npm install --save xlsx-style
2.哪个页面使用哪个页面引入
import FileSaver from "file-saver";
import XLSX2 from "xlsx";
import XLSX from "xlsx-style";
3.效果图(可以实现多表头,也可以实现单行表头)
4.页面表格需要有id(element iview都可以)
还需要一个按钮
导出
5.下面数据写在data里面 也可以改成你自己需要的数据
columns13: [
{
title: 'Date',
key: 'date',
resizable: true,
width: 180
},
{
title: 'Name',
key: 'name',
resizable: true,
width: 180
},
{
title: 'Age',
key: 'age',
resizable: true,
width: 180
},
{
title: 'Address',
key: 'address'
}
],
data5: [
{
name: 'John Brown',
age: 18,
address: 'New York No. 1 Lake Park',
date: '2016-10-03'
},
{
name: 'Jim Green',
age: 24,
address: 'London No. 1 Lake Park',
date: '2016-10-01'
},
{
name: 'Joe Black',
age: 30,
address: 'Sydney No. 1 Lake Park',
date: '2016-10-02'
},
{
name: 'Jon Snow',
age: 26,
address: 'Ottawa No. 2 Lake Park',
date: '2016-10-04'
}
]
6 .下面方法写在 methods 里面
setExport2Excel() {
/* generate workbook object from table */
var wb = XLSX2.utils.table_to_sheet(document.querySelector("#mytable")); //mytable为表格的id名
console.log(wb)
for (var i = 0; i < 11; i++) {
wb["!cols"][i] = {
wpx: 130,
};
}
// 样式的文档地址
// https://www.npmjs.com/package/xlsx-style
for (const key in wb) {
if (key.indexOf("!") === -1 && wb[key].v) {

font: {
//字体设置
sz: 13,
bold: false,
color: {
rgb: "000000", //十六进制,不带#
},

}
}
var data = this.addRangeBorder(wb["!merges"], wb); //合并项添加边框
// 暂无筛选结果 (这个位置 如果导出之后页面出现无名数据,这个暂无筛选结果,就是我写的时候的无名数据,莫名其妙就出现了,把这个不需要的,替换掉我的文字即可)
for(let i in data){
console.log(data[i].v)
if(data[i].v == '暂无筛选结果') delete data[i]
}
var filedata = this.sheet2blob(data);
this.openDownloadDialog(filedata,"日收统计.xlsx");
},

return ws;
},
//将一个sheet转成最终的excel文件的blob对象,然后利用URL.createObjectURL下载
sheet2blob(sheet, sheetName) {

};
workbook.Sheets[sheetName] = sheet; // 生成excel的配置项
var wopts = {

type: "binary",
};
var wbout = XLSX.write(workbook, wopts);
var blob = new Blob([s2ab(wbout)], {
type: "application/octet-stream",

return buf;
}
return blob;
},
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");
