열 그룹 (객체 모델 | Object Model) (Angular)

POJO 배열을 사용하여 그리드의 columnGroups 속성을 정의할 수 있을 뿐만아니라, 이러한 목적을 위해 ColumnGroup객체의 반응형 ColumnGroupCollection을 사용할 수 있습니다.

프레임워크에서는 셀 및 그룹 헤더 콘텐츠를 정의하는 셀 템플릿과 함께 프레임워크 템플릿에서 해당 컴포넌트를 사용할 수 있습니다.

이 객체 모델(Object Model)을 사용하면 전체 트리(Tree)를 다시 만들지 않고도 그룹 속성을 변경하고 그룹 트리를 재구성할 수 있습니다.
