iView Table组件二次封装

1. 使用形式: 表格组件 x-table 使用时尽量看一下源码再使用

// 并不完善 有待继续开发
x-table(:loading='loading'  // Table加载:columns='columns'  // 表格配置数据:data='featchData'  // 接口返回数据:immediately='false'// 是否立即执行 默认为true:pageSizes='[20]'   // 动态修改 pageSizes 默认为 [10, 20, 50, 100]@search='onFeatchData' // 查询数据事件
)<!-- 此处为iview表格自定义模版行为 -->template(slot-scope="{ row, index }" slot="actions")Button(type="primary" size="small" style="margin-right: 5px" @click="show(index)") ViewButton(type="error" size="small" @click="remove(index)") Delete

2. 表格组件 - 配置文件 columns.js

<!-- 配置文件 -->
|—— key   对应数据展示字段
|—— title 展示内容
|—— width 表格宽度
|—— isHideColumn 为在表格中隐藏该列展示
|—— query 查询表单配置|—— form: 'select' 表单类型|—— defaultValue: 0 默认值|—— clearable: false 是否显示清空所有 默认为true|—— options 选项配置
|—— children 子级数据export default [{key: 'card_type',title: '卡类型',isHideColumn: true,query: {form: 'select',defaultValue: 0,clearable: false,options: [{label: '全部',value: 0},{label: '实体卡',value: 2},{label: '电子卡',value: 3},]},},{key: 'query_date',title: '时间',isHideColumn: true,query: {form: 'date',defaultValue: new Date(),clearable: false,},},{key: 'window_date',title: '窗口期',isHideColumn: true,query: {form: 'select',defaultValue: 0,clearable: false,options: [{label: '0天',value: 0},{label: '3天',value: 3},{label: '7天',value: 7},{label: '15天',value: 15},{label: '30天',value: 30},]},},{key: 'ad_id',title: '计划ID',width: 200,query: {form: 'input',}},{key: 'dt',title: '日期',},{key: 'sold_unused_cnt',title: '包含子元素',children: [{key: 'total_income',title: '总收入',},{key: 'card_income',title: '售卡收入',},]},{key: 'actions',title: '操作',width: 160,<!-- 需定义slot类型 对应第12行解释 -->slot: 'actions'},
]

3. 源码

<template lang="pug">
