아래는 각 파일의 기존 구조, import, state, 함수를 모두 유지하면서, 제가 제안한 UI 개선 내용을 통합한 최종 코드입니다. 각 컴포넌트는 요청대로 바로 복사해서 사용할 수 있도록 완성했습니다.

            const { data } = await axios.get('http://localhost:3001/product/');
            setProductList(data);
        } catch (error) {
            console.error('오류 발생:', error);
        }
    }

적용 방법

이 코드는 각 컴포넌트의 기능 함수, state, import를 그대로 유지하면서, UI를 일관되게 개선한 버전입니다. 이제 이 코드를 복사해서 바로 사용할 수 있습니다. 모든 컴포넌트가 호환되며, 기존에 사용된 모든 기능도 온전히 작동합니다.
