我有一个包含两列的页面,这是一个目录页面,我想根据它们在第一列和第二列的级别值打印书签。问题是虽然打印顺序设置为vertical
,但是当jasper完成第一列时,它不会从第二列的开头开始,而是在列的末尾写入。
正如你在图片上看到的那样,我需要在第二列的开头用黄色方块作句子。

我尝试了另一种方法,其中我刚创建了一个单列的页面,然后将字段放在两个框架中,一个在左侧,另一个在页面的写入侧。但结果与之前的方法相同。 单列页面的代码:

答案 0 :(得分:2)
与您的第一次尝试相关,您误解了多个列页的工作方式。
您没有决定字段将在哪个列中进行相应的定位,而jasper-report将根据printOrder
分为下一列,如果垂直,它会在点击页面结束时中断或找到手动列中断通过组或
<break type="Column">
<reportElement x="0" y="15" width="100" height="1" uuid="c082e856-5507-4b0f-9dde-01b7fac85a4f"/>
</break>
如果您确定第一部分适合页面的第一列,则此解决方案是可行的,如果不是,它将在第二列中溢出,并且列中断将导致分页,
解决方案是对数据进行排序,然后按照下面的示例进行分组,或者通过添加上面的手动分栏符。
示例(使用此question中的数据源),当信誉小于100.000
时,请转到新列<?xml version="1.0" encoding="UTF-8"?>
