遇到一个需要根据报警级别来区分table数据的需求，一开始的想法是改变字体颜色，看了下ele文档，有个cell-style的属性，可以通过回调，返回样式。感觉so easy
那就来吧，直接上代码
界面部分
<template><div class="app-container"><div class="filter-container" ><el-button class="filter-item" type="success" >全部处理</el-button></div><el-table :data="tableData" tooltip-effect="dark" @selection-change="handleSelectionChange" :cell-style="cellStyle" border fit highlight-current-row><el-table-column type="selection" width="55" :selectable="isDisabled"></el-table-column><el-table-column label="确认" align="center" width="80"><template slot-scope="scope"><el-button type="success" size="mini" :disabled="scope.row.confirm" @click="confirmHandle(scope.row.pointId)"> {{scope.row.confirm?'已确认':'确认'}}</el-button></template></el-table-column><el-table-column label="详情" align="center" width="80"><template slot-scope="scope"><el-button type="primary" size="mini" >详情</el-button></template></el-table-column><el-table-column prop="alarmLevel" label="告警级别" align="center" show-overflow-tooltip></el-table-column><el-table-column prop="area" label="区域" align="center"></el-table-column><el-table-column prop="equip" label="设备" align="center" show-overflow-tooltip></el-table-column><el-table-column prop="pointName" label="测点" align="center" show-overflow-tooltip></el-table-column><el-table-column prop="limit" label="限值" align="center" show-overflow-tooltip></el-table-column><el-table-column prop="alarmValue" label="报警值" align="center" show-overflow-tooltip></el-table-column><el-table-column prop="alarmTime" label="报警时间" align="center" show-overflow-tooltip></el-table-column></el-table></div></template>
js部分
<script>export default {data() {return {//初始数据变量tableData: [{confirm:true,alarmLevel:"紧急告警",area:"北京市昌平区",equip:"昌平气象采集",pointId:1,pointName:"温度",limit:"35",alarmValue:"41",alarmTime:"-6-1 12:00:00",},{confirm:false,alarmLevel:"一般告警",area:"北京市朝阳区",equip:"昌平光感采集",pointId:2,pointName:"紫外线",limit:"60",alarmValue:"61",alarmTime:"-6-1 12:00:00",},{confirm:false,alarmLevel:"紧急告警",area:"北京市朝阳区",equip:"昌平光感采集",pointId:3,pointName:"紫外线",limit:"60",alarmValue:"61",alarmTime:"-6-1 12:00:00",}],multipleSelection: []}},methods: {handleSelectionChange(val) {//复选框选中操作console.log(val);},cellStyle(row,column,rowIndex,columnIndex){//根据报警级别显示颜色// console.log(row);// console.log(row.column);if(row.column.label==="告警级别"&& row.row.alarmLevel==="紧急告警"){return 'color:red'}else if(row.column.label==="告警级别"&& row.row.alarmLevel==="一般告警" ){return 'color:yellow'}}}}</script>
完成后的界面是这样婶的，感觉完全ok
后来一看字体不太清楚啊，加上颜色，盯了几秒，感觉近视又加深了啊，哈，那就换个思路，我就想试着让一行数据变背景色，只需要修改cellstyle方法中的if判断就可以了
cellStyle(row,column,rowIndex,columnIndex){//根据报警级别显示颜色// console.log(row);// console.log(row.column);if(row.row.alarmLevel==="紧急告警"){return 'background:red'}else if(row.row.alarmLevel==="一般告警" ){return 'background:yellow'}}
修改后的界面是这样婶的，没错，你没看错就这么高调，我要被亮瞎了
行吧，为了不被打死，那就缩小范围，只高亮报警级别这一项，继续修改if
cellStyle(row,column,rowIndex,columnIndex){//根据报警级别显示颜色// console.log(row);// console.log(row.column);if(row.column.label==="告警级别"&& row.row.alarmLevel==="紧急告警"){return 'background:red'}else if(row.column.label==="告警级别"&& row.row.alarmLevel==="一般告警" ){return 'background:yellow'}}
完事，是这样婶的
嗯，不愧是我写的页面，一如既往地亮眼，没有ui果然是件很蛋疼的事啊，至此功能最起码实现了
小弟刚学vue+ele，有问题的地方欢迎大佬们随时指正，告辞
