基于Vue+element-ui 的Table二次封装的实现
bilimumu 人气:0本人第一次写这个 写的不好还望指出来
作为一个由于公司产品的升级然促使我从一个后端人员自学变成前端的开发人员 ！
公司做的数据管理系统所以离不开表格了 然后表格样式统一啥的就想到封装一个element-ui 里面的table+Pagination了
效果图
表格组件的引入与使用
<com-table title="监测数据" v-model="tableData4" @selection-change="handleSelectionChange">
<template>
<el-table-column type="selection" width="55" align="center">
</el-table-column>
<el-table-column prop="name" label="表格名称" align="center">
</el-table-column>
<el-table-column label="测点" align="center">
<template slot-scope="scope" v-if="scope.row.point.visible">
<el-input v-model="scope.row.point.value" placeholder="请输入内容" @focus="focuspoint(scope.row.point)"></el-input>
</template>
</el-table-column>
<el-table-column label="项目" align="center">
<template slot-scope="scope" v-if="scope.row.item.visible">
<el-input v-model="scope.row.item.value" placeholder="请输入内容" @focus="focusitem(scope.row.item)"></el-input>
</template>
</el-table-column>
</template>
</com-table>
使用插槽slot 使用起来就和原来的table一样了
