고정된 셀 API

고정된 셀(FrozenCells) API (Angular)

셀 고정(Cell Freeze) 기능은 사용자가 특정 행과 열을 잠가 스크롤을 통해 다른 부분을 탐색하더라도 해당 행과 열이 항상 보이도록 해줍니다. 이전에는 FlexGrid에서 FrozenRows와 FrozenColumns을 사용해 상단과 왼쪽의 셀만 고정할 수 있었습니다. 이제 이 기능이 확장되어 FrozenCells를 통해 오른쪽과 하단의 셀 고정도 가능합니다.

지원되는 작업:

  1. 왼쪽 또는 오른쪽의 열 고정
  2. 상단 또는 하단의 행 고정
  3. 하나의 가로(왼쪽 또는 오른쪽)와 하나의 세로(상단 또는 하단) 고정 결합 가능

중요한 사항: frozenCells API는 네 면 모두를 고정할 수 있는 옵션을 제공하지만, 동시에 두 면에 대해서만 셀을 고정할 수 있습니다:

  • 하나의 가로 면(왼쪽 또는 오른쪽)
  • 하나의 세로 면(상단 또는 하단)

주의:

  • 왼쪽과 오른쪽 모두 설정한 경우, 왼쪽에 적용됩니다.
  • 상단과 하단 모두 설정한 경우, 상단에 적용됩니다.

이 데모는 Angular를 기반으로합니다.
