element ui Table 二次封裝
表格的分頁(yè)
- 在利用
element ui Table編寫(xiě)項(xiàng)目時(shí),會(huì)存在表格展示的數(shù)據(jù)存在分頁(yè)的情況- 普遍的做法
// 利用element ui 的 el-table與el-pagination <el-table :data="data"> <el-table-column type="selection" widht="48"></el-table-column> <el-table-column v-for="(item,index) in columns" :key="index" :lable="item.lable" :prop="item.prop"></el-table> </el-table> <el-pagination layout="prev, pager, next" :total="50"></el-pagination>每次編寫(xiě)都需要寫(xiě)那么多的標(biāo)簽與方法等，何不再進(jìn)行封裝，只需編寫(xiě)一個(gè)標(biāo)簽就完成Table表格與分頁(yè)的展示呢- 封裝后
// 新建我們的組件文件如MyTable.vue文件 <template> <div class="myTable"> <el-table :data="tableData"> <el-table-column v-if="hasSelection" type="selection" widht="48"></el-table-column> <el-table-column v-for="(item,index) in columns" :key="index" :lable="item.lable" :prop="item.prop"></el-table> </el-table> <el-pagination v-if="hasPagination" layout="prev, pager, next" :total="50"></el-pagination> </div> </template> <script> export default { name:'myTable', props:{ hasSelection:{ type:Boolean, default:false }, hasPagination:{ type:Boolean, default:false }, tableData:{ type:Object, default:()=>{return {}} }, columns:{ type:Object, default:()=>{return {}} } }, data(){ return {} }, } </script>- 在需要使用的頁(yè)面使用
<template> <myTable :hasSelection="hasSelection" :hasPagination="hasPagination" :tableData="tableData" :columns="columns"></myTable> </tempalte> <script> import myTable from '@/components/MyTable' export default { name:'***', components:{myTable} data(){ return { hasSelection:true, hasPagination:true, tableData:{} // tableData根據(jù)后臺(tái)接口數(shù)據(jù)返回 } } computed:{ columns(){ // 表頭信息 /** * 表頭信息為什么寫(xiě)在computed里面 * 由于我最近所的項(xiàng)目是基于i18n國(guó)際化的 * 如果寫(xiě)在data里面，不能根據(jù)i18n的語(yǔ)言切換實(shí)時(shí)進(jìn)行切換 **/ return [ {lable:'標(biāo)題1',prop:'title1'}, {lable:'標(biāo)題2',prop:'title2'}, {lable:'標(biāo)題3',prop:'title3'}, ] } } } </script>這樣我們就實(shí)現(xiàn)了簡(jiǎn)單的table表格封裝，在需要使用的地方直接引入我們封裝好的組件傳入對(duì)應(yīng)對(duì)應(yīng)的參數(shù)就能實(shí)現(xiàn)表格的展示與分頁(yè)和選擇框的展示了。
列表中單元格的內(nèi)容自定義
- 上面我們已經(jīng)實(shí)現(xiàn)了簡(jiǎn)單的'element ui Table'封裝，但是還是不能實(shí)現(xiàn)一些復(fù)雜的表格展示，如圖1：
