详解使用element-ui table组件的筛选功能的一个小坑

使用element-ui table组件的筛选功能的一个小坑

使用自定义模板和筛选功能，一开始的代码

  <el-table-column v-if="key==='isShow'" label="是否在发现页展示" :filters="[{text:'已展示',value: true},{text: '未展示', value: false}]" :filter-method="filterShow">        <template slot-scope="scope">          <el-tag type="success" v-if="scope.row.isShow">显示</el-tag>          <el-tag type="danger" v-else>不显示</el-tag>        </template>      </el-table-column>      <el-table-column v-else-if="key==='isHandle'" label="是否已经审核" :filters="[{text:'已处理',value: true},{text: '未处理', value: false}]" :filter-method="filterHandle">        <template slot-scope="scope">          <el-tag type="info" v-if="scope.row.isHandle">已处理</el-tag>          <el-tag type="warning" v-else>未处理</el-tag>        </template>      </el-table-column>

然后发现筛选功能怎么都不能实现，上网查找原因才发现，虽然官网在写自定义模板的示例代码时是这样的：

<template> <el-table  :data="tableData"  style="width: 100%">  <el-table-column   label="日期"   width="180">   <template slot-scope="scope">    <i class="el-icon-time"></i>    <span style="margin-left: 10px">{{ scope.row.date }}</span>   </template>  </el-table-column>  <el-table-column   label="姓名"   width="180">   <template slot-scope="scope">    <el-popover trigger="hover" placement="top">     <p>姓名: {{ scope.row.name }}</p>     <p>住址: {{ scope.row.address }}</p>     <div slot="reference" class="name-wrapper">      <el-tag size="medium">{{ scope.row.name }}</el-tag>     </div>    </el-popover>   </template>  </el-table-column>  <el-table-column label="操作">   <template slot-scope="scope">    <el-button     size="mini"     @click="handleEdit(scope.$index, scope.row)">编辑</el-button>    <el-button     size="mini"     type="danger"     @click="handleDelete(scope.$index, scope.row)">删除</el-button>   </template>  </el-table-column> </el-table></template><script> export default {  data() {   return {    tableData: [{     date: '2016-05-02',     name: '王小虎',     address: '上海市普陀区金沙江路 1518 弄'    }, {     date: '2016-05-04',     name: '王小虎',     address: '上海市普陀区金沙江路 1517 弄'    }, {     date: '2016-05-01',     name: '王小虎',     address: '上海市普陀区金沙江路 1519 弄'    }, {     date: '2016-05-03',     name: '王小虎',     address: '上海市普陀区金沙江路 1516 弄'    }]   }  },  methods: {   handleEdit(index, row) {    console.log(index, row);   },   handleDelete(index, row) {    console.log(index, row);   }  } }</script>
