使用Vue3+ts开发ProTable源码，需要先了解Vue3、TypeScript和ProTable的相关知识。以下是开发教程及示例。
1. 安装ProTable
首先需要安装ProTable，在命令行中执行:
npm install @ant-design-vue/pro-table --save
2. 搭建Vue3项目
使用Vue CLI创建Vue3项目：
vue create my-project
安装Vue Router和Vuex：
npm install vue-router vuex --save
在main.js中导入并挂载Vue Router和Vuex：
import { createApp } from 'vue';
import App from './App.vue';
import router from './router';
import store from './store';
createApp(App).use(router).use(store).mount('#app');
3. 创建ProTable组件
在/src/components目录下创建ProTable.vue文件：
<template>
<div>
<a-table :columns="columns" :data-source="dataSource"></a-table>
</div>
</template>
<script lang="ts">
import { defineComponent } from 'vue';
import { Table } from 'ant-design-vue';
export default defineComponent({
name: 'ProTable',
components: { Table },
props: {
data: {
type: Array,
required: true
},
},
data() {
return {
columns: [
{ title: '姓名', dataIndex: 'name', key: 'name' },
{ title: '年龄', dataIndex: 'age', key: 'age' },
{ title: '地址', dataIndex: 'address', key: 'address' },
],
dataSource: []
};
},
watch: {
data: {
immediate: true,
handler(newVal, oldVal) {
this.dataSource = newVal;
}
},
}
});
</script>
4. 在页面中使用ProTable组件
在/src/views目录下创建Home.vue文件：
<template>
<div>
<h1>ProTable示例</h1>
<ProTable :data="data"></ProTable>
</div>
</template>
<script lang="ts">
import { defineComponent } from 'vue';
import ProTable from '@/components/ProTable.vue';
export default defineComponent({
name: 'Home',
components: { ProTable },
data() {
return {
data: [
{ key: '1', name: 'John Brown', age: 32, address: 'New York No. 1 Lake Park' },
{ key: '2', name: 'Jim Green', age: 42, address: 'London No. 1 Lake Park' },
{ key: '3', name: 'Joe Black', age: 32, address: 'Sidney No. 1 Lake Park' },
]
};
},
});
</script>
然后在/src/router/index.ts中配置路由：
import { createRouter, createWebHistory, RouteRecordRaw } from 'vue-router';
import Home from '../views/Home.vue';
const routes: Array<RouteRecordRaw> = [
{
path: '/',
name: 'Home',
component: Home,
},
];
const router = createRouter({
history: createWebHistory(process.env.BASE_URL),
routes,
});
export default router;
启动项目，即可看到ProTable示例。
示例1：基于ProTable的表格分页功能
我们希望在表格中实现分页功能，需要在ProTable.vue组件中添加pagination数据绑定：
<template>
<div>
<a-table :columns="columns" :data-source="dataSource" :pagination="pagination"></a-table>
</div>
</template>
<script lang="ts">
import { defineComponent } from 'vue';
import { Table } from 'ant-design-vue';
export default defineComponent({
name: 'ProTable',
components: { Table },
props: {
data: {
type: Array,
required: true
},
},
data() {
return {
columns: [
{ title: '姓名', dataIndex: 'name', key: 'name' },
{ title: '年龄', dataIndex: 'age', key: 'age' },
{ title: '地址', dataIndex: 'address', key: 'address' },
],
dataSource: [],
pagination: {
current: 1,
pageSize: 2,
total: 0,
showSizeChanger: false,
showQuickJumper: true,
onChange: this.handlePageChange,
onShowSizeChange: this.handlePageSizeChange
}
};
},
watch: {
data: {
immediate: true,
handler(newVal, oldVal) {
this.dataSource = newVal;
}
},
},
methods: {
handlePageChange(currentPage) {
console.log(currentPage);
},
handlePageSizeChange(pageSize, currentPage) {
console.log(pageSize, currentPage);
},
}
});
</script>
然后在Home.vue组件中修改测试数据，大于两条才能触发分页功能：
data() {
return {
data: [
{ key: '1', name: 'John Brown', age: 32, address: 'New York No. 1 Lake Park' },
{ key: '2', name: 'Jim Green', age: 42, address: 'London No. 1 Lake Park' },
{ key: '3', name: 'Joe Black', age: 32, address: 'Sidney No. 1 Lake Park' },
{ key: '4', name: 'Jonson Zhang', age: 28, address: 'Beijing No. 1 Lake Park' },
{ key: '5', name: 'Lucy Liu', age: 24, address: 'Hangzhou No. 1 Lake Park' },
]
};
},
然后就可以在页面中看到分页功能了，当数据超过一页时，会根据设置显示分页控件。
示例2：基于ProTable的表格列排序
我们希望在表格中实现列排序功能，需要在ProTable.vue组件中的相应列添加customSorter方法：
<template>
<div>
<a-table :columns="columns" :data-source="dataSource"></a-table>
</div>
</template>
<script lang="ts">
import { defineComponent } from 'vue';
import { Table } from 'ant-design-vue';
export default defineComponent({
name: 'ProTable',
components: { Table },
props: {
data: {
type: Array,
required: true
},
},
data() {
return {
columns: [
{ title: '姓名', dataIndex: 'name', key: 'name' },
{ title: '年龄', dataIndex: 'age', key: 'age', customSorter: function(a, b) {
return a.age - b.age;
} },
{ title: '地址', dataIndex: 'address', key: 'address' },
],
dataSource: []
};
},
watch: {
data: {
immediate: true,
handler(newVal, oldVal) {
this.dataSource = newVal;
}
},
},
});
</script>
然后在Home.vue组件中添加测试数据，以年龄为例：
data() {
return {
data: [
{ key: '1', name: 'John Brown', age: 32, address: 'New York No. 1 Lake Park' },
{ key: '2', name: 'Jim Green', age: 42, address: 'London No. 1 Lake Park' },
{ key: '3', name: 'Joe Black', age: 26, address: 'Sidney No. 1 Lake Park' },
{ key: '4', name: 'Jonson Zhang', age: 28, address: 'Beijing No. 1 Lake Park' },
{ key: '5', name: 'Lucy Liu', age: 24, address: 'Hangzhou No. 1 Lake Park' },
]
};
},
然后在页面中测试，点击“年龄”列标题可以对表格数据进行排序。
