vue封装element 中table组件

1、知识点

插槽
组件

2、项目初始化

• 使用vue-cli3 安装项目 vue create ‘项目名’
• npm install element-ui -s

3、父组件 List.vue

<template>
    <div class="table-section">
        <common-table
        :column="column"
        :tableData="tableData"
        :pageVo="pageVo"
        @handleCurrentChange="handleCurrentChange"
        >
        <!-- ID -->
        <template v-slot:id="{row}">
            <div class="pub-status">
                VIP
                <span class="triangle-up"></span>
            </div>
            {{row.id}}
        </template>
        <!-- 性别 -->
        <template v-slot:sex="{row}">

    },
    components:{
        CommonTable
    },
    methods:{
        /**
         * 页码改变
         */
        handleCurrentChange (val) {

</script>

<style lang="scss" scoped>
.table-section{
    width:100%;
    .pub-status{
        display: inline-block;
        position: absolute;
        top:0px;
        left:0px;

        color: #fff;
        font-size: 12px;
        transform: scale(0.8);//chrome默认最小字体是12px，将字体变成10px
        .triangle-up{
            width:0;
            height:0;

    }
    .gray-text{
        color:darkgray;

</style>

4、子组件 CommonTable.vue

<template>
    <div class="common-table">
        <el-table
            :data="tableData"
            stripe
            header-cell-class-name="header-cell-class-name"
            style="width: 100%">
             <!-- 
                    1、slot-scope="scope" 获取到el-table子组件的内容
                    2、<slot v-if="item.scopeStatus" :name="item.prop" :row="scope.row"></slot>将子组件的内容传给父组件
                 -->
            <template  
                v-for="(item,index) in column">
                    <el-table-column
                    :key="index"
                    :width="item.width?item.width:'auto'"
                    :min-width="item.minWidth"
                    :prop="item.prop"
                    :align="item.align?item.align:'center'"
                    :label="item.label">
                    <template slot-scope="scope">
                        <slot v-if="item.scopeStatus" :name="item.prop" :row="scope.row" >
                        </slot>
                        <template v-else>
                            {{scope.row[item.prop]}}
                        </template>
                    </template>
                </el-table-column>
            </template>
        </el-table>
        <el-pagination v-if="!!tableData.length" class="pagination"
            @current-change="handleCurrentChange"
            :current-page="pageVo.currentPage"
            :page-size="pageVo.pageSize"
            layout="total, prev, pager, next, jumper"
            :total="pageVo.total">
        </el-pagination>
    </div>
</template>

<script>
export default {
    props:{
        tableData:{
            type:Array
        },
        column:{
            type:Array
        },
        pageVo:{
            type:Object
        }
    },
    methods:{
        handleCurrentChange(val){
            this.$emit('handleCurrentChange',val)
        }
    }
}
</script>

<style >

</style>

5、项目入口 main.js

import Vue from 'vue'
import App from './App.vue'
import router from './router'
import store from './store'
import ElementUI from 'element-ui'
import 'element-ui/lib/theme-chalk/index.css'
Vue.use(ElementUI)

Vue.config.productionTip = false

new Vue({
  router,
  store,
  render: h => h(App)
}).$mount('#app')
