element-ui表格的selectable属性使用

需求：表格的多选框状态根据数据判断，可以勾选和不可以勾选；

先本地测试一波看看效果；

<template>
  <div class="content-box">
    <div class="container">
      <h3>多选框显示和隐藏，根据状态可选和不可选</h3>
      <el-button @click="clearSelection()">取消选择</el-button>
      <el-button @click="showSelection()" v-if="cancelReport">
        取消报备
      </el-button>
      <el-button @click="sureCancel()" v-else>确认取消</el-button>
      <div>
        <el-table
          ref="multipleTable"
          :data="tableData"
          tooltip-effect="dark"
          style="width: 100%"
          @selection-change="handleSelectionChange"
        >
          <transition name="el-fade-in-linear">
            <el-table-column
              type="selection"
              width="55"
              v-if="showSelect"
              :selectable="selectable"
            ></el-table-column>
            <!-- v-if="showSelect" -->
          </transition>

          <el-table-column label="日期" width="120">
            <template slot-scope="scope">{{ scope.row.date }}</template>
          </el-table-column>
          <el-table-column
            prop="name"
            label="姓名"
            width="120"

          <el-table-column
