vue+element+echarts常用组件1、(面包屑、操作区、表格)，方便快速搭建页面

  1、面包屑，页面上方使用

  <el-row style>
      <el-breadcrumb
        separator-class="el-icon-arrow-right"
        style="
          margin-left: 2%;
          vertical-align: middle;
          height: 30px;
          line-height: 30px;
        "
      >
        <el-breadcrumb-item :to="{ path: '/home' }">首页</el-breadcrumb-item>
        <el-breadcrumb-item>{{ typeName1 }}</el-breadcrumb-item>
        <el-breadcrumb-item>{{ typeName }}</el-breadcrumb-item>
      </el-breadcrumb>
    </el-row>
 
data() {
    return {
      typeName1: "安规违章管理",
      typeName: "安规条款",
    };
  },

 2、操作区，包含（新建、修改、删除、关键字查询，导入、导出、下拉框刷选、开始日期、结束日期、优化用户体验，每个操作都触发搜索函数刷新页面）

   <el-row
      :gutter="14"
      style="margin-left: calc(2% - 12px); margin-top: 10px;"
    >
      <el-col :span="3" style="margin-left:5px">
        <el-select
          v-model="RuleLevel"
          clearable
          placeholder="条例级数"
          @change="selectUser"
        >
          <el-option
            v-for="(item, index) in list1"
            :label="item.label"
            :value="item.value"
          ></el-option>
        </el-select>
      </el-col>
      <!-- <el-col :span="3">
           <el-select v-model="ruleNum" placeholder>
                <el-option v-for="(item,index) in list2" :label="item.name" :value="item.value"></el-option>
              </el-select>
      </el-col>-->
      <el-col :span="6">

      <el-col :span="2">
