Jasper reports 动态更改元素的宽度

我需要在JasperReports中创建目录。 我已经做到了这一点，但不能做任何事与线在TOC

当前它们具有静态宽度：

Chapter 1          ........ 2
Long Chapter Name  ........ 3
End                ........ 4

我想把虚线延伸到章节名称的宽度。就像这里：

Chapter 1 ................. 2
Long Chapter Name ......... 3
End ....................... 4

我该怎么做？JR中是否有一些“填充”功能，或者我是否应该为此任务创建scriptlet？谢谢

另外，我使用的是jasper reports 5.0.1，这不是一个很好的方法，但我会在你的文本框中画很多点，并用一个框架隐藏结尾，以允许写页码

很棒的黑客。我一定会用的。但是我担心我不能为段落定制行。当它裁剪圆点的时候，看起来不太好。很棒的技巧。我一定会用的。但是我担心我不能为段落定制行。当它裁剪圆点的时候，看起来不太好。
