我同意伊斯钦的答复,但我将阐述。
跨表格报告将使你能够有动态的栏目,因为它使你能够利用你的数据。 你们可以选择一个或多个领域,以建立一栏。 这些集团的数值成为各栏的标签,因此,你必须利用“措施”报告中的数值(如总和或计值)的合计功能。 如果你选择一个以上的领域,你将拥有多个层次的栏目。 在你设计报告时,你选择一栏的大小,其大小必须相同。
JasperReports是一种产品,目的是像人民抵抗力量一样,在纸面上制造一些东西。 i 报告至少为5.1.0本,没有其他办法真正动态地建立栏目。 你可以按照逻辑写出,显示或隐藏基于参数的栏目,但这会非常虚伪,不符合Jasper报告的设计。 例如,很难允许用户管理报告,以选择使用户能够控制报告中的栏目和各栏的位置。
