코드는 칼럼 0에서 각 행 (studentList.size() + 2 행 3) studentList의 값을 기록하고 컬럼으로부터 gradesList (1 행에서 기록을 사용하여 엑셀의 셀을 강조하는 방법 1 to gradesList.size() +1) 출석 도표

연두색으로 모든 studentList를 강조 표시하고 밝은 주황색으로 gradesList를, 노란색으로 Title (머리글)을 나머지 부분을 강조 표시하려면 어떻게해야합니까? 하늘색 상자가있는 빈 상자? Image 2 I need my sheet to look like this

당신은 당신이 국경을 만들 때 그것을 무시 다음 라인 5의 배경 색상을 생성되지만로 이미지 1에서 내 시트를 변환하는 데 도움이 필요합니다. 문제를 해결하려면 동시에 모든 스타일을 적용해야합니다.

그 외에도, 당신은 예를 들어 FillPattern을 포함해야한다 :

 style.setFillForegroundColor(HSSFColor.GOLD.index); 
     style.setFillPattern(CellStyle.SOLID_FOREGROUND);
