我在所有地方搜索但找不到明确答案：是否可以创建一个 JasperReport的报告，其中包含 List，其中包含另一个List（或表） ？如果是，我如何将参数传递到内部列表？
我尝试在 iReport 中实现此功能，并收到以下异常：

我刚刚遇到这个错误。后来我发现方法net.sf.jasperreports.components.table.FillTableFactory.cloneFillComponent实际上直到6.0.0才实现。所以我用6.0.0替换了旧的Jasperreport Library，问题解决了。

是的，将“Subdataset”的概念作为表格包含在详细信息区域中。 C.F.官方IReport文档（ireport-ultimate-guide.pdf）在他们的网站上。
