Question

使用jasper api打印结果集时，我遇到了一个问题。

说明：

报告格式：

GroupA(GroupHeader)

SubGroupName(SubGroup Header)

....Data(Detail Section).....

条件：

如果我的子组标题或GroupHeader看起来位于页面底部，我想插入分页符，以便下一页显示标题部分和数据。

示例：

实际输出：

GroupA(GroupHeader)

SubGroupName(SubGroup Header)

<unwanted Pagebreak>
....Data(Detail Section).....

预期输出：

我想避免不需要的Pagebreak.so我的输出看起来像

GroupA(GroupHeader)

SubGroupName(SubGroup Header)

....Data(Detail Section).....

我的JRXML文件：
