[踩坑记录] el-table的row-class-name标签不生效

问题描述与需求

最后两行的占比统计数据需要加入底色进行凸显

根据官方文档提供的解决方法，给el-table加上row-class-name后未生效

 

 

 

 

 

问题记录

1. 尝试给css加上!important提高优先级，依旧未生效

2. 检查元素发现标签确实加上了count-row的样式

 

 

<!--表格-->
    <el-table :data="tableData" :span-method="arraySpanMethod" style="width: 100%" :row-style="{height: '38px'}" :cell-style="{padding: '0'}" :row-class-name="tableRowClassName" :tree-props="{ children: 'children', hasChildren: 'hasChildren' }" row-key="id">

      <el-table-column min-width="6%" prop="province" label="合计(吨)" align="center"></el-table-column>
    </el-table>

// 统计行染色
    tableRowClassName ({ row, rowIndex }) {
      if (row.type === 'percent') {
        console.log(row, rowIndex)
        return 'count-row'
      }
      return ''
    },

<style scoped>
  .el-table .count-row {
    background: #F8F8F8 !important;
  }
</style>

 

问题解决

去掉样式标签的scoped使样式变为全局样式，问题解决

<style>
  .el-table .count-row {
    background: #F8F8F8;
  }
</style>
