element-ui上传组件bug

 <el-row :span="24">
            <el-form-item
              label="宠物照片"
              prop="imageUrl"
              style="width: 1000px"
            >
              <el-upload
                action="#"
                list-type="picture-card"
                :on-preview="handlePictureCardPreview"
                :on-remove="handleRemove"
                :multiple="true"
                :http-request="uploadAvatar"
                :limit="4"
                disabled
                :before-upload="beforeAvatarUpload"
                :file-list="fileList"
                :on-exceed="handleExceed"
                :class="{ disabled: status == '详情' }"
              >
                <i class="el-icon-plus"></i>
              </el-upload>
              <el-dialog :visible.sync="dialogVisible" append-to-body>
                <img width="100%" :src="dialogImageUrl" alt="" />
              </el-dialog>
            </el-form-item>
          </el-row>

问题：就是没有预览和删除按钮遮盖层，很像个被禁用一样

• 解决 上传组件必须外面独占一行 el-row 包裹才行，切记不能el-col
