vue table表格中如何控制下拉框的显示隐藏

        <vxe-table-column align="center" title="类型" width="270" style="height:40px;" field="collectionType">
          <template slot-scope="scope">
            <!--                 @change="changeSelect(scope,$event)"
                @visible-change="handleBlur(scope,$event)" -->
            <el-select v-if="scope.row.isModifiy2" ref="goodsSelect" v-model="scope.row.collectionType" size="mini" placeholder="请选择" @visible-change="handleBlur(scope,$event)" @change="changeSelect(scope.row,$event)">
              <el-option v-for="item in selectData" :key="item.value" :label="item.label" :value="item.value" />
            </el-select>
            <template v-else><div style="cursor:pointer">{{ scope.row.collectionType }}</div></template>
          </template>

      const index = this.dataTable.findIndex((item) => { return column.property === item.prop })
//获取点击值那一列的索引
      if (!this.dataTable[index]) return
      if (this.dataTable[index].isModifiy !== undefined) {
        row.isModifiy = true
        this.dataTable[index].isModifiy = true
        //上面的isModifiy是为了解决复杂的表单需要的设置
        this.dataTable = Object.assign([], this.dataTable)
        //要进行数据的深拷贝，不然第一次点击的时会有点问题
        this.$nextTick(() => {

<Select ref="vendorId" v-model="formInline.vendorId" @on-open-change="venSelect" filterable style="width: 162px;" @on-change="vendorChange"
            v-if="vendorShow">
            <Option v-for="item in vendorList" :value="item.vendorId" :key="item.vendorId">{{ item.venAbbName + '-' + item.vendorCode }}</Option>
  </Select>

// 重置
      reloadFun() {
        this.formInline = {
          vendorId: '',
          productCode: '',
          inventoryCode: '',
          sendDate: '',
          remark: '',
          cwhCode:''
        }
        this.$refs.vendorId.query = ''//.query是因为this.$refs.vendorId只能清空展示的下拉框的数据，不能清空底层的数据所以要.query清空底层数据
        this.tableData = []
      },
