vue element table 传值报错 _self.$scopedSlots.default is not a function

所以直接在要动态渲染的tabel上面增加key就行了

 <el-table ref="multipleTable" :data="tableData3" tooltip-effect="dark" style="width: 100%" @selection-change="handleSelectionChange">
    <el-table-column type="selection" width="55" key='selection' v-if="isShow"></el-table-column>
    <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>
    <el-table-column prop="address" label="地址" show-overflow-tooltip></el-table-column>
</el-table>
