antdv table组件封装成全局组件以及携带自定义表头展示_antvtable

1、封装table组件

// tableBox.vue
<template>
  <div class="table-c">
    <a-table
      :expandIcon="customIcon"
      :columns="tableColumns"
      :data-source="dataSource"
      :pagination="pagination"
      :loading="loading"
      :rowSelection="rowSelection"
      @change="change"
      @expand="expand"
    >
      <template
        v-for="i in tableColumns"
        :key="i.key"
        v-slot:[i.slots?.customRender]="{ record }"
      >
        <slot :name="i.slots?.customRender" :record="record"></slot>
      </template>

      <template v-slot:[expandedRowRender]="{ record }">
        <slot name="expandedRowRender" :record="record"></slot>
      </template>
    </a-table>
    <a-modal
      title="列表设置"
      v-model:visible="visible"
      :width="800"
      :confirmLoading="tableHeadLoading"
      :bodyStyle="{
        paddingBottom: '10px',
      }"
    >
      <a-checkbox-group v-model:value="tableHead" class="checked-item">
        <a-row>
          <a-col
            :span="5"
            v-for="check in columns"
            :key="check.key"
            :offset="1"
          >
            <a-checkbox :value="check.key" :disabled="check.key == 'action'">
              <span
                v-text="check.key == 'action' ? '操作' : check.title"
              ></span>
            </a-checkbox>
          </a-col>
        </a-row>

            <a-button @click="checkAll">全选</a-button>
            <a-button @click="checkNoAll">全不选</a-button>
          </div>
          <div class="btn-right">
            <a-button @click="handleHeadCancel">返回</a-button>
            <a-button type="primary" @click="setConfirm" class="ok-btn"
              >确定</a-button
            >
          </div>

2、在main.js中把组件全局上

import {
  createApp
} from 'vue';
import App from './App.vue';
import router from './router/index.js';
import store from './store';
import {
  changeSize
} from './utils/common.js';
import antd from 'ant-design-vue';
import tableBox from "@/components/tableBox.vue";
import 'ant-design-vue/dist/antd.less';
import './assets/common/style.less';
import 'nprogress/nprogress.css'

changeSize()
const app = createApp(App)
app.component('table-box', tableBox);
app.use(antd).use(router).use(store).mount('#app')

3、在组件中的使用， 因为父子组件的生命周期的原因，所以使用v-if控制子组件的渲染

// index.vue
<table-box
  v-if="isShow"
  :columns="state.columns"
  :dataSource="state.tableData"
  :pagination="pagination"
  :rowSelection="rowSelection"
  @change="handleTableChange"
  :routerName="routerName"
>
	<template v-slot:expandedRowRender="{ record }">
      <span>{{ record }}</span>
  </template>
  <template #action="{ record }">
    <a-popover title="">
      <template #content>
        <div
          class="action-box"
          style="display: flex; flex-direction: column"
        >
          <a @click="handleEdit(true, record)">修改</a>
          <a @click="handleDel(record.id)" href="javascript:void(0)"
            >删除</a
          >
        </div>
      </template>
      <MenuOutlined />
    </a-popover>
  </template>
</table-box>
<script setup>
import { useRoute } from "vue-router";
const route = useRoute();

      abbreviation: "汇水创",
      address: "高塘石",
      liaison: "陈辉",
      liaisonPhone: "1371507698",
    });
  }
};
const rowSelection = {
  onChange: (selectedRowKeys, selectedRows) => {
    state.selectedRowKeys = selectedRowKeys;
    console.log(
      `selectedRowKeys: ${selectedRowKeys}`,
      "selectedRows: ",
      selectedRows
    );
  },
};
// 切换页
const handleTableChange = (page, filters, sorter) => {
  pagination.current = page.current;
  pagination.pageSize = page?.pageSize;
  // console.log(filters); // 选中值为数组（单选直接拿第一项，多选把数组转化成字符串拼接 - 看后台需要什么数据结构）
  if (filters.type) {
    // 必须判断，未操作切换页会报错（无type属性）
    formData.type = filters.type[0];
  }
  getTableData(formData);
};
onMounted(async () => {
 // 判断是否已经设置过表头，有则使用
  if (
    sessionStorage.tableHeadObj &&
    JSON.parse(sessionStorage.tableHeadObj)[routerName.value]
  ) {
    let arr = JSON.parse(sessionStorage.tableHeadObj)[routerName.value];
    for (let i = 0; i < state.columns.length; i++) {
      if (arr.indexOf(state.columns[i].key) == -1) {
        state.columns[i].isShow = false;

4、表头数据vuex + sessionStorage (key为路由的名称 – 唯一性)

// store.js
import {
  createStore
} from "vuex";
export default createStore({
  state: {
    tableHeadObj: sessionStorage.tableHeadObj ? JSON.parse(sessionStorage.tableHeadObj): {}
  },
  mutations: {
    setTableHeadObj(state, obj) {
      state.tableHeadObj = obj;
      sessionStorage.tableHeadObj = JSON.stringify(state.tableHeadObj);
    }
  }
