CollectionView (React)

CollectionView 클래스는 Wijmo 컨트롤과 함께 사용되는 기본 데이터 관리 클래스입니다. 이 샘플은 ICollectionView의 작동 방식을 보여 줍니다. 500개 항목이 포함된 배열을 기준으로 CollectionView 객체를 만듭니다. CollectionView는 기본적으로 각각 10개 항목이 포함된 페이지를 표시하도록 구성되어 있습니다. 컬렉션은 HTML 표로 표시되며, 표에서 각 열의 맨 위에 있는 컨트롤을 사용하여 필터링, 정렬, 그룹화할 수 있습니다.

이 데모는 React를 기반으로합니다.
