이곳에서 JPR reader가 읽어주는 항목과 아이템을 설정할 수 있습니다.
항목과 아이템의 설정 방법은 셀을 더블 클릭한 후 이름을 입력하는 방식으로진행됩니다.
그 후 떠오른 파일 탐색기에서 지정할 mp3파일을 선택해 주세요.
설정의 확인은 셀의 색으로 확인 가능합니다. 지정이 완료된 항목은 노란색, 아이템은 하늘색으로 표시됩니다.
지정이 되지 않은 셀은 빨간색으로 표시됩니다. 행과 열 버튼으로 테이블의 크기를 조절할 수 있으며
초기화시 모든 설정은 사라지며 테이블은 5by5로 초기화 됩니다.
<<<주의사항>>>
1. 첫번째 열은 반드시 항목을 입력해 주세요.
2. 입력되는 이름은 엑셀파일에서 표현된 명칭과 완벽히 일치해야 합니다.(엔터나 스페이스, 오타 주의!)
3. 초기화를 누르면 처음부터 모든 항목과 아이템을 지정해야 합니다.
4. 엑셀 파일의 ()나 /을 통해 구분한 아이템은 따로 입력해 주세요.
5. 사용하는 엑셀파일의 구조를 유지해 주세요. 변경시 프로그램의 수정이 필요할 수 있습니다.(예: '박스'항목은 항상 있을 것으로 간주됩니다.)
