【uniapp】通用列表封装组件

uniapp页面一般都会有像以下的列表页面，封装通用组件，提高开发效率；
（基于uView前端框架）

首先，通过设计图来分析一下页面展示和数据结构定义

w-table组件参数说明

prop-list具体参数说明

propList数据格式

propList:[{label:'废物名称',prop:'title',show:true},{label:'数字识别码',prop:'name',show:true},{label:'危废标识',prop:'tag',show:true},{label:'废物代码',prop:'code',show:true},{label:'废物重量',prop:'weight',formatValue:true,show:true},//格式化值{label:'废物形态',prop:'name'},{label:'主要成分',prop:'name'},{label:'有害成分',prop:'name'},{label:'危险特性',prop:'name'},{label:'注意事项',prop:'name'},{label:'产生/收集单位',prop:'comp'},{label:'联系人',prop:'userName'},{label:'联系方式',prop:'phone'},{label:'产生日期',prop:'date'},{label:'备注',prop:'remark'},{label:'状态',prop:'status',formatItem:true,show:true},//格式化列默认展示{label:'二维码',prop:'qrcode',formatItem:true,show:false}//格式化列默认不展示
]

tableData数据格式

tableData:[{title:'HWCS20230908003',time:'2023-09-18 14:00',name:'废物名称',code:'1234567890123456789000030420230915101',tag:'7b9e9d22ca714365a1f6a6b338fc8fa3',code1:'900-041-49',weight:'30',unit:'kg',wasteStatus:1,reportStatus:0,
}]

具体代码

基础用法

<w-table :table-data="tableData" :prop-list="propList" :toggle="true"></w-table>

有格式化值和列的情况

<w-table :table-data="tableData" :prop-list="propList" :toggle="true"><template slot="header" slot-scope="scope"><view class="width w-flex row row-between borderB padding16"><view class="flex1 w-flex row"><text class="fs24 c-blue fwBold marginR10 flex-none"> {{scope.index < 10 ?'0'+(scope.index+1):scope.index+1}} </text><text class="flex1 text-overflow c-text fs16">{{scope.row.title}}</text></view><text class="marginLR10 flex-none">{{scope.row.time}}</text></view></template><template slot="weight" slot-scope="scope"><span>{{scope.row.weight}}{{scope.row.unit}}</span></template><template slot="status" slot-scope="scope"><view class="w-flex row row-between paddingLR30 paddingTB10"><u-tag text="待入库" mode="plain"/><view v-if="scope.row.status == 0" class="" style="color:#FF7D00"><u-icon name="clock"></u-icon><text class="marginL10">未上报</text></view><view v-else class="" style="color:#00B42A"><u-icon name="checkbox-mark"></u-icon><text class="marginL10">已上报</text></view></view></template><!-- 二维码 --><template slot="qrcode" slot-scope="scope"><view class="w-flex"> <img class="width160 height160" src="/static/img/qrcode.png" alt=""></view></template></w-table>
