vue 根据数组对象里面的某个属性值进行从大到小，从小到大排序

vue 表格里 根据数组对象里面的某个属性值进行从大到小，从小到大排序 （vue表格日期排序）

<template>
  <div class="hello">
    <el-table :data="newList" stripe style="width: 100%">
      <el-table-column prop="data" label="日期" width="180"></el-table-column>
      <el-table-column prop="name" label="姓名" width="180"></el-table-column>
      <el-table-column prop="age" label="年龄"></el-table-column>
    </el-table>
  </div>
