vue3+Ts+elementPlus二次封装Table分页表格，表格内展示图片、switch开关、支持

一.项目文件结构

二.实现代码

1.子组件（表格组件）

2.父组件（使用表格）

一.项目文件结构

1.表格组件（子组件）位置

2.使用表格组件的页面文件（父组件）位置

3.演示图片位置

elementPlus表格 Table 表格 | Element Plus

4.笑果演示

表格笑果

点击图片放大显示笑果

二.实现代码

1.子组件（表格组件）

1. src/views/Table.vue html部分

<!-- 表格区域 传值格式 -->
<!-- 单行文字：{ prop: 'inventory', label: '库存', width: '90' }, -->
<!-- 图片格式：{ prop: 'profile_picture_url', label: '商品主图', width: '110', isImg: true, height: 50 }, -->
<!-- 双行文字格式：{ prop: 'information', label: '商品信息', width: '140', doubleRow: true, text1: '货号', text2: '售价' }, -->
<!-- 开关格式：{ prop: 'listed', label: '是否上架', width: '110', isSwitch: true, }, -->

js部分

javascript"><script setup lang='ts'>
import { ref, computed, defineProps, onMounted, defineEmits } from 'vue';
// 父传子
const props = defineProps({columns: {// 表头数据type: Array,validator: () => {return [];}},paginatedData: {// 表格数据type: Array,validator: () => {return [];}},btnListTable: {// 按钮组type: Array,validator: () => {return [];}},isFixedColumn: {// 是否有操作列type: Boolean,default: true},isSelected: {// 是否有选择框type: Boolean,default: false},tableLoading: {// 是否加载中type: Boolean,default: false,},
});// 操作列 更多按钮组
const btnListTable2 = ref(props.btnListTable.slice(1))
// 多选
interface User {id: numberdate: stringname: stringaddress: string
}
// 选择的内容
const multipleSelection = ref<User[]>([])
const selectable = (row: User) => ![1, 2].includes(row.id)
const handleSelectionChange = (val: User[]) => {multipleSelection.value = val
}
// 分页
const currentPage = ref(1);
const pageSize = ref(10);
const disabled = ref(false)
const background = ref(false)
const enlargedImageUrl = ref('');
const dialogVisible = ref(false);// 点击图片事件
const handleImageClick = (imageUrl: any) => {enlargedImageUrl.value = imageUrl;dialogVisible.value = true;

2.父组件（使用表格）

1.src/views/Dashboard.vue html部分

<template><div><Table :columns="columns" :paginatedData="paginatedData" :btnListTable="btnListTable":isFixedColumn="true" :tableLoading="loading" @pageSize="handlePageSize" @currentPage="handleCurrentPage"></Table></div>
</template>
