我们正在从 Ext JS UI生成 Excel 报告，该报告包含一些过滤器参数和一个按照所选过滤器获取数据的按钮。数据显示在过滤器组件下方的 Ext JS 网格中。在导出数据期间，过滤器参数将放在 Excel 的工作表1和要放入工作表2中的数据。这适用于 JasperReports jar 4.7.0但是使用 JR jar 5.1.2，过滤器详细信息和数据在同一个工作表中。请注意，没有代码更改，只是jar已更改。
如果我遗失了什么，请告诉我。
下面是jrxml和几行 Java 代码：

加载jrxml
JasperDesign jasperDesignObj = JRXmlLoader.load(ReportUtil.getJRXMLResourcePath(reportType, CommonConstants.JRXML_EXTENSION));
JRBeanCollectionDataSource beanColDataSource = new JRBeanCollectionDataSource(dataProviderList);
JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesignObj);
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, parameters, beanColDataSource);
jasperPrint.getPages（）。size（）返回2 4.7.1但1返回5.1.2，不知道这是怎么回事。
