AG-GRID cellRenderer 예제

까오기 2019. 1. 30. 14:21

Cell Renderer & Style & Drop Down 설정 예제 

값을 받아서 보여줄 때 가공을 해야 하는 경우가 있습니다. 

코드인 경우 코드의 값으로 전환해야 하고 필요한 경우 그래프나 아이콘, 이미지 등으로 보여 줘야 할 때도 있습니다. 

그런 경우 cellRenderer를 이용해서 표현할 수 있습니다. 

예제코드로는 세가지를 확인해 볼 수 있습니다. 

1. cell에 스타일 적용하기. 

- 정렬 또는 background color 등을 지정할 수 있습니다. 

2. data renderering

- 숫자는 오른쪽 정렬을 해야 하며 세자리 마다 콤마를 찍어 줘야 합니다.  

- Style, Use는 코드 값을 받으며 Value로 표현해야 합니다. 

3. Data 편집시 drop down 박스 처리 (중요)

- 여기서는 단순히 표현에 대한 것만 예제로 만들었습니다. 

- ag-grid나 다른 곳에 관련 소스를 찾기가 어려워 많이 고생을 했던거 같습니다. 

- Use를 클릭하면 drop down박스에 value를 보여 주고 code로 저장이 되어야 합니다. 

- cellEditorParams, valueFormatter, valueParser, cellRenderer 네가지 설정이 필요합니다.

- 이 부분은 실무 적용 시 부딛치는 문제라 나중에 적용시 확인하실 수 있습니다.
