一行一个标签对应多个输入组件，这个需求很常见但在官方例子没看到合适的，因为官方建议：

注意：一个 Form.Item 建议只放一个被 getFieldDecorator 装饰过的 child，当有多个被装饰过的 child 时，help required validateStatus 无法自动生成。 

经过摸索，证实这样写是可行的，如下：

<Form.Item
            label={'模块'}
          >
            <Row gutter={30}>
              <Col span={8}>
                <Form.Item>
                  {getFieldDecorator('module1', {
                    rules: [{ required: true, message: '请输入模块1' }],
                  })(<Input placeholder={'请输入模块1'} />)}
                </Form.Item>
              </Col>
              <Col span={8}>
                <Form.Item>
                  {getFieldDecorator('module2', {
                    rules: [{
                      required: true,
                      // tslint:disable-next-line:max-line-length
                      pattern: /(^[1-9][0-9](\.\d)?$)|(^[1-9](\.\d)?$)|(^0\.\d$)/,
                      message: '请输入正确的模块',
                    }],
                  })(<Input placeholder={'请保留一位小数'} />)}
                </Form.Item>
              </Col>
            </Row>
</Form.Item>
