elementUI跨页多选行实现

使用这个属性可以在分页切换后保留选中内容

<!-- 出库统计报表 -->
<template>
  <div class="app-container">
    <div class="formClass" style="border-bottom: 2px solid #e7eaec">
    <div>
    <!-- <el-table ref="multipleTable" @selection-change="handleSelectionChange" row-key="id" :data="tableData" 这里不能使用slection-change
        style="width: 100%" -->
        <el-table ref="multipleTable" @select="handleSelectionChange" row-key="id" :data="tableData"
        style="width: 100%">
        <el-table-column type="selection" width="55" :reserve-selection="true">
        </el-table-column>
      </el-table>
    </div>

  </div>
