有什么解决的方案吗
<template>
<!--定义大小框架-->
<div class="Account">
<div class="AccountList">
<el-table :data="tableData" border height="660" style="width: 100%">
<el-table-column type="selection" width="30"></el-table-column>
<el-table-column label="序号" width="48">
<template slot-scope="scope">
<span style="margin-left: 5px">{{ scope.row.date }}</span>

</el-table-column>
<el-table-column label="账号" width="200">
<template slot-scope="scope">
<div slot="reference" class="name-wrapper">

getAccount(){
var fs=require('fs');
var data=fs.readFileSync('user.json').toString();
let resdata = data.split("\r");
var results=[];
for (let index = 0; index < resdata.length; index++) {
if (resdata[index]!='') {
results.push(

name:resdata[index],

mounted(){

}
};
DOM节点太多了吧
执行一下document.all 查看一共有多少个节点 几千个都话就会有卡顿的感觉了
建议数据多的话 还是以 分页 形式来渲染
