vue2+ant-design-vue table的使用：cus

vue2+ant-design-vue table的使用：customRender

需求情况：customRender使用了合并列，就没办法使用slot了

解决方法：

<a-table
          :columns="columns"
          row-key="userId"
          :data-source="dataSource"
          :pagination="false"
          :loading="loading"
          class="x-table"
        >
          <span slot="planNameTitle">{{$t('stats.tab1Text1')}}</span>
          <span slot="nameTitle">{{$t('stats.tab1col1')}}<b>{{'('+userTotal+')'}}</b></span>
          <span slot="supervisorTitle">{{$t('stats.tab1col2')}}</span>
          <span slot="percentageTitle">{{$t('stats.tab1col3')}}</span>
          <span slot="overdueCountTitle">{{$t('stats.tab1col4')}}</span>
          <span slot="actionTitle">{{$t('stats.tab1col5')}}</span>
          <span slot="action" slot-scope="text, record">
          <span class="btn ant-dropdown-link" @click="handleGoDetail(record)">
              <!-- 查看详情 -->{{$t('staff.tableDetail')}}
              <i class="iconfont icon-zhankai"></i>
          </span>
          </span>
          <span slot="percentage" slot-scope="text, record">
            <span>{{record.finishCount | progressPanel(record.allCount)}}</span>
          </span>
</a-table>
