二次封装lement组件遇到的问题

Question

封装的通用查询组件出了bug

时间回显和选中的不一样

废话不多说 先上代码

<template>
  <div>
    <cc-Table :tableList="tableList"></cc-Table>
  </div>
</template>

<script>
import CcTable from '../components/Table.vue'
export default {
  components: {
    CcTable
  },
  data () {
    return {
      tableList: {
        // 后台接口
        apiUrl: 'www.baidu.com',
        // 搜索
        serch: [
          { id: '1', label: '姓名', type: 'input', key: 'name' },
          { id: '2', label: '年龄', type: 'input', key: 'age' },
          {
            id: '3',
            label: '性别',
            type: 'select',
            key: 'sex',
            info: [
              { key: '0', value: '男' },
              { key: '1', value: '女' }
            ]
          },
          { id: '4', label: '开始时间', type: 'dateYmd', key: 'startTime' },
          { id: '5', label: '结束时间', type: 'dateYmd', key: 'endTime' }
        ],
        // 表格头部
        list: [
          { id: '1', prop: 'name', label: '姓名', width: '180' },
          { id: '2', prop: 'age', label: '年龄', width: '180' },
          { id: '3', prop: 'sex', label: '性别', width: '180' }
        ]
      }
    }
  },
  methods: {
    // 发送请求
    getTableList () {

    }
  },
  created () {
    this.getTableList()

封装的表格组件

    <!-- 表格组件 -->
    <el-table
      :data="tableData"
      style="width: 100%">
      <el-table-column
        v-for="item in tableList.list" :key="item.id"

Answer 1

清空了值，没有把传进来的值赋给form
this.$set(this.form, [item.key], '')
如果这是回显赋值的代码，问题就在这里
应该是
this.$set(this.form, item.key, item.value)
