父组件和配置文件

因为是封装的原因，所以只要看:<page-content />组件和配置文件contentTableConfig

user.vue

<template>
  <div class="user">
    <page-content
      :contentTableConfig="contentTableConfig"
      pageName="users"
    ></page-content>
  </div>
</template>

<script lang="ts">
import { defineComponent } from "vue";
//引入展示 table 组件
import PageContent from "@/components/page-content";
//引入展示 table 组件的数据和配置
import { contentTableConfig } from "./config/content.config";

export default defineComponent({
  name: "users",
  components: {
    PageContent
  },
  setup() {
    return {
      contentTableConfig
    };
  }
});
</script>

<style scoped>
.content {
  padding: 20px;
  border-top: 20px solid #f5f5f5;
}
</style>

content.config.ts

export const contentTableConfig = {
  title: "用户列表",
  propList: [
    { prop: "name", label: "用户名", minWidth: "100" },
    { prop: "realname", label: "真实姓名", minWidth: "100" },
    { prop: "cellphonne", label: "电话号码", minWidth: "200" },
    { prop: "enable", label: "状态", minWidth: "100", slotName: "status" },
    {
      prop: "createAt",
      label: "创建时间",
      minWidth: "230",
      slotName: "createAt"
    },
    {
      prop: "updateAt",
      label: "更新时间",
      minWidth: "230",
      slotName: "updateAt"
    },
    { label: "操作", minWidth: "120", slotName: "handler" }
  ],
  showIndexColumn: true,
  showSelectColumn: true
};

子组件

page-content.vue

<template>
  <div class="page-content">
    <hy-table v-bind="contentTableConfig" :listData="dataList">
      <!-- 1.header 中的插槽 -->
      <template #headerHandler>
        <el-button type="primary" size="medium">新建用户</el-button>
      </template>

      <!-- 2.列中的插槽 -->
      <template #status="scope">
        <el-button
          plain
          size="mini"
          :type="scope.row.enable ? 'success' : 'danger'"
        >
          {{ scope.row.enable ? "启用" : "禁用" }}
        </el-button>
      </template>
      <template #createAt="scope">
        <span>{{ $filters.formatTime(scope.row.createAt) }}</span>
      </template>
      <template #updateAt="scope">
        <span>{{ $filters.formatTime(scope.row.updateAt) }}</span>

演示 contentTableConfig 传输过程

• 1.通过 import 导入到 user.vue 里，给 page-content.vue 子组件传过去
• 2.组件 page-content.vue 继续把 contentTableConfig 传递给子组件 HyTable.vue
• 3.然后 HyTable.vue 组件解析

问题出在哪儿了？
