element plus table封装_element-plus table封装

前言

在table数据请求的过程 过于频繁，从而导致页面代码多，封装的目的就是减少相同代码，提高在开发中的效率

封装的目的及好处

• 隐藏实现细节，逻辑统一处理，只需传递参数内容
• 低耦合，利于全局扩展，继承所有elemenet plus table的属性及方法
• 只需配置一个参数及可控制列的显示和隐藏

源码

• table-props.ts

import { ExtractPropTypes, PropType } from 'vue'

export const tableProps = {/** 是否显示分页 */pagination: {type: Boolean,default: true},/** 请求地址 */url: {type: String,default: ''},/** 默认数据源 */data: {type: Array,default: () => []},/** 请求参数 */params: {type: Object,default: () => ({})},/** 是否立即请求 */init: {type: Boolean,default: true},/** 是否重新加载 */reload: {type: Boolean,default: false},/** 默认显示列 */defaultColumns: {type: Array as PropType<string[]>,default: () => []}
}
export type TableProps = ExtractPropTypes<typeof tableProps>
