实现表格双击后变输入框

双击后效果,本次需求我的代码中始终只会保持一个输入框    每次都会执行stopEditing 函数

还有一种实现方式就是在tableData2中的每一个对象中加一个布尔值,然后失焦、聚焦的时候 直接修改这个值显示 

    <!-- 编辑测量数据弹框 -->
    <Dialog title="编辑测量数据" width="1200px" :visible.sync="editMeasureShow" append-to-body v-dialogDrag>
      <el-table
        :data="tableData2"
        class="tableData2_class"
        border
        stripe
        :header-cell-style="{
          background: '#f1f3f5',
          color: '#000000'
        }"
      >
       
        <el-table-column align="center" prop="weight" label="重量(KG)">
          <template v-slot="{ row }">
            <div
              style="width: 100%; cursor: pointer"
              @dblclick="startEditing(row, 'weight')"
              v-if="!row.isEditingWeight"
            >
              {{ row.weight || '--' }}
            </div>
            <el-input
              v-else
              ref="weightInput"
              v-model="row.weight"
              @blur="stopEditing(row, 'weight')"
              @keyup.enter="stopEditing(row, 'weight')"
              type="number"
              size="mini"
            ></el-input>
          </template>
        </el-table-column>
        <el-table-column align="center" prop="length" label="长(CM)">
