客户想要这种合并单元格后的变色效果
如果不处理的话，出来的是这种每一行都变色的效果，页面显得不整齐并且眼花缭乱的
代码如下：
<template>
<div class="version-contrast__content">
<el-table :data="tableData" :stripe="false" :span-method="spanMethod" :row-class-name="rowClass">
<el-table-column prop="num" width="60" label="序号"></el-table-column>
<el-table-column prop="indexType" label="指标类别"></el-table-column>
<el-table-column prop="indexName" label="指标名称"></el-table-column>
<el-table-column prop="unit" label="单位"></el-table-column>
<el-table-column prop="panoramicMeeting" label="全景会"></el-table-column>
<el-table-column prop="lastMonthDynamic" label="上月动态"></el-table-column>
<el-table-column prop="thisMonthDynamic" label="本月动态"></el-table-column>
<el-table-column width="170" prop="difference" label="差异(本月动态版-全景会)"></el-table-column>
<el-table-column prop="differenceRate" label="差异率">
<template slot-scope="scope">
