vue+element 前端实现增删查改+分页，不调用后端

前端实现增删查改+分页，不调用后端。
大概就是对数组内的数据进行增删查改+分页
没调什么样式，不想写后端，当做练习

<template>
  <div>
    <!-- 查询 -->
    <el-form :inline="true" :model="formQuery">
      <el-form-item label="时间" :label-width="formLabelWidth">
        <el-date-picker
          v-model="formQuery.date"
          type="daterange"
          value-format="yyyy-MM-dd"
          start-placeholder="开始日期"
          end-placeholder="结束日期"
          :default-time="['00:00:00', '23:59:59']">
        </el-date-picker>
      </el-form-item>
      <el-form-item label="姓名" :label-width="formLabelWidth">
        <el-input
          v-model="formQuery.name"
          style="width: 240px"
          placeholder="Please input"
          clearable />
      </el-form-item>
      <el-form-item label="地址" :label-width="formLabelWidth">
        <el-input
          v-model="formQuery.address"
          style="width: 240px"
          placeholder="Please input"
          clearable />
      </el-form-item>
      <el-form-item>

        <el-button type="success" @click="add()" class="addButton">添加</el-button>
      </el-form-item>
    </el-form>
