프런트엔드는 JQgrid를 기반으로 사용자 정의된 열 헤더 표시를 구현합니다.

먼저 렌더링

회사 프로젝트의 요구 사항으로 인해 저는 회사에서 js를 작성할 수 있는 유일한 프런트엔드이기 때문에 jqgrid 열 옵션 표시를 사용자 정의해야 하는 필요성은 여전히 ​​제가 작성해야 할 몫으로 남아 있습니다. 내 작업 결과를 공유하겠습니다.

몇 가지 참고 사항:

• 1 매개변수 옵션을 명확하게 읽어야 합니다. html 및 js

• 2에는 주석이 있습니다. 3.jquery 버전 1.11.0

• 이 기능에서 주목해야 할 점은 매개변수 전달과 호출 위치입니다. 이제 요점이 명확해졌으니 이 기능이 필요한 친구들은 사용해도 됩니다~~
