iText를 사용하여 내 주 PdfP 테이블의 첫 번째 행과 두 번째 행을 함께 유지하는 데 문제가 있습니다. 내 첫 번째 행은 몇 가지 기본 정보가있는 PdfPTable로 구성됩니다. 내 두 번째 행은 모든 테이블 정보를 포함하는 PdfPTable로 구성됩니다. 표 정보가 너무 커지고 여러 페이지에 걸쳐있을 때마다 기본 정보 바로 아래에 표시되고 다음 페이지로 페이징되지 않고 자동으로 두 번째 페이지로 이동합니다. 이 문제를 어떻게 피할 수 있습니까? setSplitRows (false)를 사용하여 시도했지만 빈 문서 만 얻습니다 (주석 된 줄 117 및 170 참조). 첫 페이지에서 어떻게 표의 데이터 (두 번째 행)를 유지할 수 있습니까? 내 코드 예제는 아래에 나와 있습니다 (복사/붙여 넣기 만 가능).iText는 행을 함께 보관할 수 없습니다. 두 번째 행은 여러 페이지에 걸쳐 있지만 첫 행에는 붙지 않습니다.
