table表格中使用el-popover 无效问题解决

实例只针对单个的按钮管用在表格里每一列都有el-popover相当于是v-for遍历了 所以我们在触发按钮的时候并不是单个的触发某一个 

主要执行 代码

<el-popover placement="left" :ref="`popover-{scope.index}`"> 动态绑定了ref

关闭弹窗 执行deltaskList

  <el-table-column align="center" label="操作" fixed="right" width="300px">
          <!-- v-buttonShow="5010403" -->
          <template slot-scope="scope">

            <el-popover placement="left" :ref="`popover-${scope.$index}`">
              <div style="border-bottom: 1px solid #ebeef5; margin-bottom: 10px; padding-bottom: 6px">设置账期</div>
              <div style="display: flex; flex-direction: column">
                仅记录账期，并不会影响出账流程~
                <el-select
                  v-model="setAccountVal"
                  clearable
