成功vue el-date-picker后台接收不到数据解决

以前是这样，接收不到数据

<el-table-column prop="TreatmentTime" label="治疗时间" align="center">

          <template scope="scope">

            <el-date-picker

              v-model="scope.row.TreatmentTime"

              type="month"

              value-format="yyyy-MM-dd"

              placeholder="选择日期时间"

              size="mini"

            ></el-date-picker>

          </template>

        </el-table-column>

改成：

<el-table-column prop="TreatmentTime" label="治疗时间" align="center">

          <template scope="scope">

            <el-date-picker

              v-model="scope.row.TreatmentTime"

              type="month"

              value-format="yyyy-MM-dd HH:mm:ss""

              placeholder="选择日期时间"

              size="mini"

            ></el-date-picker>

          </template>

        </el-table-column>

就接收到数据了
