1:安装xlsx和file-saver
npm install file-saver xlsx --save
2:创建localExports.js文件
3：直接上代码
import XLSX from 'xlsx';
const FileSaver = require('file-saver');
import { getRandomNum } from '@/utils';
// 本地导出表格
export function exportsXlsx(elementName, fileName) {
const time = new Date().getTime();
const random = getRandomNum(100, 1000);
const wb = XLSX.utils.table_to_book(clearHead(elementName), { raw: true });
const wbout = XLSX.write(wb, { bookType: 'xlsx', bookSST: true, type: 'array' });
FileSaver.saveAs(new Blob([wbout], { type: 'application/octet-stream' }), `${fileName}${time}-${random}.xlsx`);
}
function clearHead(elementName) {
const tableDom = document.querySelector('#' + elementName).cloneNode(true);
const tableHeader = tableDom.querySelector('.el-table__header-wrapper');
const tableBody = tableDom.querySelector('.el-table__body');
tableHeader.childNodes[0].append(tableBody.childNodes[1]);
const headerDom = tableHeader.childNodes[0].querySelectorAll('th');
// 移除左侧checkbox的节点
if (headerDom[0].querySelectorAll('.el-checkbox')) {
headerDom[0].remove();
}
for (const key in headerDom) {
if (headerDom[key].innerText === '操作') {
headerDom[key].remove();
}
}
// 清理掉checkbox 和操作的button
const tableList = tableHeader.childNodes[0].childNodes[2].querySelectorAll('td');
for (let key = 0; key < tableList.length; key++) {
if (tableList[key].querySelectorAll('.el-checkbox').length > 0 || tableList[key].querySelectorAll('.el-button').length > 0) {
tableList[key].remove();
}
}
return tableHeader;
}
4：使用方式
<el-table
id="good"
v-loading="listLoading"
:header-cell-style="{ background: '#FAFAFA', color: '#212532' }"
:data="list"
tooltip-effect="dark"
style="width: 100%"
height="566"
border
@selection-change="handleSelectionChange"
>
import { exportsXlsx } from '@/utils/localExports';
methods:{
onSearch() {
exportsXlsx('good', '模拟数据');
},
}5:good为table组件的id，getRamdomNum方法如下
// 生成随机数
export function getRandomNum(Min, Max) {
var Range = Max - Min;
var Rand = Math.random();
return (Min + Math.round(Rand * Range));
