통합 문서 뷰어

이 샘플은 xlsx 파일 내용을 로드하고 페이지에 표시하는 간단한 Excel 통합 문서 뷰어를 구현합니다.

샘플은 통합 문서 인스턴스를 만들고, Workbook.load 메서드를 사용하여 xlsx 파일 내용을 통합 문서 인스턴스에 로드합니다. 그런 다음, WorkSheet 클래스에서 제공하는 현재 통합 문서 시트의 콘텐츠를 검색하고 콘텐츠를 시각화하는 HTML 표를 만듭니다.

통합 문서 시트 간에 전환할 수 있도록 탭도 만듭니다. Workbook.sheets 컬렉션을 반복하는 ng-repeat 지시문이 적용된 <li> 요소의 스타일 지정과 비슷한 BootstrapJS 탭을 사용하여 탭을 구현합니다.
