1、需求描述

最后一行总计不参与排序

2、配置属性方法

el-table 需要配置 @sort-change="soltHandle" 方法
el-table-column 需要配置 sortable="custom"属性

3、详细代码如下

<el-table
   v-loading="loading"
   border
   :data="stationTableData"
   :header-cell-style="{ 'text-align': 'center' }"
   :cell-style="{ 'text-align': 'center' }"
   style="width: 100%"
   height="470"
   stripe
   :row-class-name="rowClass"
   class="table-style"
   @sort-change="soltHandle"
 >
   <el-table-column
     prop="name"
     label="电站名称"
     width="150"
   ></el-table-column>
   <el-table-column prop="province" label="所属省份" width="100">
     <template slot-scope="{ row }">
       {{ getChineseName(row.province).value }}
     </template>
   </el-table-column>
   <el-table-column
     prop="operationDate"
     label="投运时间"
     width="100"

     prop="discharge"
     label="放电量(kWh)"
     width="120"
   ></el-table-column>
   <el-table-column
     prop="saveElectricity"
     label="节约电费(元)"
