今天实习要完成一个数据表格的小案例,要求是能根据数据的严重程度,在页面上显示不同的样式。
我是使用element-ui
中的表格组件对数据进行处理,在处理的过程中就掉进坑里。el-table
组件结合插槽和数据格式化(formatter
)时,是数据格式化是不会生效的。
解决方法:只能自己封装el-table
中formatter
方法
<template>
<div class="app">
<el-card class="box-card" shadow="always">
<div slot="header">
<span class="title">异常警告信息</span>
</div>
<el-table :data="tableData" style="width: 100%" size="small" height="275" :fit="false">
<el-table-column prop="id" label="序号"> </el-table-column>
<el-table-column prop="level" label="警告级别">
<!--
插槽
scope 代表的是 tableData 数据
scope.row 代表这一行的数据
-->
<template slot-scope="scope">
<div class="cell" v-html="formatter(scope.row.level)"></div>
</template>
</el-table-column>
<!--:show-overflow-tooltip='true' 溢出隐藏 -->
<el-table-column prop="info" label="信息" width="78" :show-overflow-tooltip='true'> </el-table-column>
<el-table-column prop="time" label="时间" width="168">
</el-table-column>
</el-table>
</el-card>
</div>
</template>
