这就是效果图，在项目中的效果,效果也简单就是想记录一下
下面附的代码是在页面做的实例：
html:

<template>
  <div class="hello">
    <el-table class="tablessp" :data="tableData" highlight-current-row @current-change="handleCurrentChange" ref="multipleTable" @select="handleSelect" @selection-change="handleSelectionChange"  border fit highlight-current-row
        style="width:700px;min-height:260px;margin-top:8px;" height="260"
        :header-cell-style="{background:'#199ED8'}">
        <el-table-column type="selection" width="60" align="center"></el-table-column>
          <el-table-column prop="workSheetCode" label="工单编号" min-width="180" align="center">
          </el-table-column>
          <el-table-column prop="subProductCode" label="部件编号" min-width="180" align="center">
          </el-table-column>
          <el-table-column prop="lineName" label="生产线名称" align="center" min-width="150">
