all right, that's good. LabelCol= {{span: 8}} wrapperCol= {{span: 16}
means that the proportion of tags is 8x24. WrapperCol means that the proportion of tags is 16. 24.

const formItemLayout = {
      labelCol: {
        xs: { span: 24 },
        sm: { span: 8 },
      },
      wrapperCol: {
        xs: { span: 24 },
        sm: { span: 16 },
      },
    };
    
   <Form.Item
          {...formItemLayout}
          label=""
        >
          {getFieldDecorator('date-picker', config)(
            <DatePicker />
          )}
  </Form.Item>
