jasper-reports - 如何在页面末尾画一条线？

Question

我正在研究 Jasper Reports。在我的报告中，我希望我的数据具有如下所示的边框样式

 ______ ______ ______ ______|__H1__|__H2__|__H3__|__H4__|  |      |      |      |      ||      |      |      |      | |      |      |      |      ||      |      |      |      | |______|______|______|______|----------Page Footer--------

我想获取每页最后一行的底部边框。我目前得到的是类似

 ______ ______ ______ ______|__H1__|__H2__|__H3__|__H4__|  |      |      |      |      ||      |      |      |      | |      |      |      |      ||      |      |      |      | 

页脚需要有一个空隙，所以我不能在页脚中使用一行。此外，如果我确实在页脚中使用了一行，则报告的最后一行将没有底部边框。

有没有办法根据页面的最后一行有条件地启用底部边框？

Answer 1

然后画线 columnFooter Band 并设置 isFloatColumnFooter="true"

isFloatColumnFooter=true, render column footer just below the last detail or group footer on that particular column

输出(使用 5 条记录的空数据源运行)

Note, when creating reports as invoice's etc, with fix lines on page (that does not depend on datasource) the background band can be used.
