vue3 + tsx 表格 Action 单独封装组件用法

前言

先上图看右侧列 action 的 UI 效果：

正常来说，如果一个表格的附带 action 操作，我们一般会放在最右侧的列里面实现，这个时候有些UI 框架支持在 SFC 模板里面定义额外的 solt，当然如果不支持，更通用的做法是通过 vue 的 h 函数来实现，纯粹用 js 或 ts 组装组件方式实现，这种方式很灵活，但有一个弊端，当定义的组件很多的时候，比如上图有4 个Button，还得定义按钮样式和点击事件，代码就显的非常乱。

更为优雅的做法是，把这一小块的功能给单独定义成一个 vue 组件，可以用 SFC 也可以用 JSX/TSX 实现，然后事件通过回调完成，代码就显得非常整洁了。

定义 Action 组件

这里用 tsx 实现：

import { defineComponent, PropType, toRefs } from 'vue'
import { NSpace, NTooltip, NButton, NIcon, NPopconfirm } from 'naive-ui'
import {AreaChartOutlined, DeleteOutlined, EditOutlined,
PlayCircleOutlined,PauseCircleOutlined,RedoOutlined,AlignCenterOutlined} from "@vicons/antd";
import {SolrListActionModel} from "@/service/middleware/types";const props = {row: {type: SolrListActionModel as PropType<SolrListActionModel>}
}export default defineComponent({name: 'SolrTableAction',props,emits: ['start','stop','restart','showLog',],setup(props, ctx) {const handleStartAction = () => {ctx.emit('start')}const handleStopAction = () => {ctx.emit('stop')}const handleRestartAction = () => {ctx.emit('restart')}const handleShowLogAction = () => {ctx.emit('showLog')}return {handleStartAction,handleStopAction,handleRestartAction,handleShowLogAction,...toRefs(props)}},render() {return (<NSpace>{this.row?.start ? <NTooltip trigger={'hover'}>{{default: () => "启动",trigger: () => (<NButtonsize='small'type='info'tag='div'circleonClick={this.handleStartAction}class='btn-edit'><NIcon><PlayCircleOutlined></PlayCircleOutlined></NIcon></NButton>)}}</NTooltip>:""}{this.row?.stop?<NTooltip trigger={'hover'}>{{default: () => "停止",trigger: () => (<NButtonsize='small'type='info'tag='div'circleonClick={this.handleStopAction}class='btn-edit'><NIcon><PauseCircleOutlined></PauseCircleOutlined></NIcon></NButton>)}}</NTooltip>:""}{this.row?.restart?<NTooltip trigger={'hover'}>{{default: () => "重启",trigger: () => (<NButtonsize='small'type='info'tag='div'circleonClick={this.handleRestartAction}class='btn-edit'><NIcon><RedoOutlined></RedoOutlined></NIcon></NButton>)}}</NTooltip>:""}{this.row?.showLog?<NTooltip trigger={'hover'}>{{default: () => "日志",trigger: () => (<NButtonsize='small'type='info'tag='div'circleonClick={this.handleShowLogAction}class='btn-edit'><NIcon><AlignCenterOutlined></AlignCenterOutlined></NIcon></NButton>)}}</NTooltip>:""}{this.$slots.extraAction?.()}</NSpace>)}
})

在 Table 列里面引用

定义好之后，在 table 里面引用就非常简单了，只需要把 props 属性传递一下，然后定义回调处理事件即可：

        const columns = [{title: '服务名',key: 'server_name',align: 'center'},{title: '运行状态',key: 'process_state',align: 'center'},{title: '主机IP',key: 'process_ip',align: 'center'},{title: '启动信息',key: 'process_description',align: 'center'},{title: '操作',key: 'operation',//列宽自适应...COLUMN_WIDTH_CONFIG['operation'](4),align: 'center',render: (row: SolrList)=>{let model=new SolrListActionModel(row)return  h(SolrTableAction, {row: model,onStart: () => {},onStop:()=>{},onRestart:()=>{},onShowLog:()=>{}})}}] as TableColumns<any>

列宽自适应工具类

这个是为了该列的宽度，根据实际情况重新分布：
