我在JasperReports中收到警告如何解决？

Question

我是JasperReports的新手,我已经将插件添加到我的netbeans IDE中,我正在尝试使用表创建一个报表,我还在iReport设计器中设计了一个表,并且我将它连接到sql数据库,当我点击预览按钮我收到以下警告

Blockquote net.sf.jasperreports.engine.design.JRValidationException:报告设计无效:1.警告:元素底部到达带外区域:y = 0 height = 140 band-height = 61 at net.sf.jasperreports.engine.design .JRAbstractCompiler.verifyDesign(JRAbstractCompiler.java:271)at net.sf.jasperreports.engine.design.JRAbstractCompiler.compileReport(JRAbstractCompiler.java:153)at net.sf.jasperreports.engine.JasperCompileManager.compile(JasperCompileManager.java:354) )在net.sf.jasperreports.engine.JasperCompileManager.compileToFile(JasperCompileManager.java:270)的net.sf.jasperreports.engine.JasperCompileManager.compileReportToFile(JasperCompileManager.java:563)at com.jaspersoft.ireport.designer.compiler. IReportCompiler.run(IReportCompiler.java:528)org.openide.util.RequestProcessor $ Task.run(RequestProcessor.java:572)atg.openide.util.RequestProcessor $ Processor.run(RequestProcessor.java:997)

请提前帮助我解决此警告的朋友

Answer 1

它清楚地"Element bottom reaches outside band area : y=0 height=140 band-height=61"表明你有一个坐标为y = 0和height = 140的元素.所以你的乐队高度必须大于0 + 140 = 140.但是目前它是61,如错误信息中所述.
