话不多说直接上代码，首先我们先封装el-table组件，里面的item都是日常用到的基本el-table-column，对于复杂的el-table-column 我们可以定义插槽进行自定义扩展

<style lang="scss" scoped>
</style>具体如何使用呢，我这里也把几个场景的代码贴出来，
首先先引入并注册组件，这里贴上template中使用的代码
<SimpleTable :data="tableData" :columns="columns" :rowClass="rowClass" :pagination="pagination" @handleCurrentChange="handleCurrentChange" @changeCurrent="changeCurrent">
<el-table-column slot="action" :align="'center'" :label="'操作'" width="150">
<template slot-scope="scope">
<el-button type="text" size="small" @click="operationStation(6,scope.row)" class="qgreen" >查看
</el-button>
<el-divider
direction="vertical"
></el-divider>
<!-- <el-button type="text" size="small" @click="editRecord(scope.row)" class="qgreen">
修改
</el-button>
<el-divider direction="vertical" ></el-divider> -->
<el-button type="text" size="small" @click="batchDel(1,scope.row.cardNo)" class="color-danger" >
删除
</el-button>
</template>
</el-table-column>
</SimpleTable>这是date里的数据，type:'selection' 是表单多选checkbox，formatter是定义每列数据的格式化，
slot则是定义的具名插槽，这里的name:"action"要和上面的slot="action"保持一致
tableData:[],
columns:[
{ type:'selection'},
{ type:'index'},
{ type:'text',key:'cardNo',label:'卡号'},
{ type:'text',key:'batchId',label:'批次号'},
{ type:'text',key:'firstSubjectName',label:'合作机构名称'},
{ type:'text',key:'cardStatus',label:'会员卡状态',formatter:this.cellFormatter},
{ type:'text',key:'cardType',label:'会员卡类型',formatter:this.cellFormatter},
{ type:'text',key:'durationDays',label:'可用时间（天）'},
{ type:'text',key:'qrCodeGenerated',label:'二维码生成',formatter:this.cellFormatter},
{ type:'date',key:'lastActivityTime',label:'最后激活时间'},
{ type:'slot',name:"action"}
]
pagination: {
current: 1,
size: 10,
total: 1,
},这里是methods代码
// 根据列的值动态显示样式 仅为示例，具体根据自身业务更改
rowClass(col){
if(col.column.property === 'qrCodeGenerated'){
return col.row.qrCodeGenerated === 'NO' ? 'color-danger' : 'color-success'
}
},
// 每列对应需要格式化的内容
cellFormatter(row, column, cellValue, index){
let showLabel =''
if(column.property === 'cardStatus'){
this.cardStatus.forEach(x=>{
if(x.value === cellValue){
showLabel= x.label
}
})
}
……
if(column.property === 'qrCodeGenerated'){
showLabel= cellValue === 'YES'? '是':'否'
}
return showLabel || '-'
},
至此二次封装的table就可以愉快的使用了，有什么问题给我留言吧...
