您可以使用net.sf.jasperreports.export.{format}.exclude.origin.{suffix}.{arbitrary_name}(有关详细信息,请参阅http://jasperreports.sourceforge.net/config.reference.html页面)属性不包括导出器的带区(在您的情况下为页眉和页脚)。

iReport中的报表设计:
JRPdfExporter的结果将是:
两个波段都存在于PDF文件中
JRCsvExporter的结果将是(输出csv文件):
AAA,US,XXXXX
BBB,UK,XXXXX
CCC,ID,XXXXX
DDD,CC,XXXXX
EEE,SA,XXXXX
FFF,ZM,XXXXX
CSV文件中不存在这两个波段。
如您所见,我仅针对JRCsvExporter排除了两个波段( Page Header和Page Footer ) 。
