jasper报告excel工作表前面的空白页

Question

我已经开发了一份包含10个子报告的碧玉报告 1.每个子报告都在单独的细节范围内。 2.在详细信息区域中的每个子报表之后放置的break元素，用于导出excel工作表中的每个页面。 我将每个元素都放在单独的Excel工作表中，但在第一个工作表中，我得到一个空白页面，其中包含第一个子报表的标题。 任何人都可以帮助我吗？ 请找到主报告的jrxml

Answer 1

将@harun prasu评论移至答案（社区维基）

通过在包含break元素的band表达式时给出print来解决。

 <printWhenExpression><![CDATA[$V{PAGE_NUMBER}==0]]></printWhenExpression>  
 <textField>
   <reportElement x="0" y="10" width="100" height="1" uuid="ddf8561d-a742-4ee5-9504-4e2b4a979735"> 
   <property name="com.jaspersoft.studio.unit.y" value="pixel"/> 
   <property name="com.jaspersoft.studio.unit.height" value="pixel"/> 
   <property name="net.sf.jasperreports.export.xls.break.after.row" value="true"/> 
   </reportElement>
