Java “详细信息”部分在字段之间留有空格。我怎样才能消除这种情况？

我正在使用最新版本的Jasper Reports。我在Jasper Reports的详细部分使用了两个框架。其中一个框架包含所有需要的字段，设置为top=0，第二帧正好位于第一帧的下方，并且只包含一个字段。当第一帧的文本字段中的文本在宽度范围内正常匹配且不拉伸时，结果为正常，表示第二帧正好打印在第一帧的下方。但是如果其中一个文本字段被拉伸，如果内容溢出，那么它会在两个帧之间留下一些空间

我在这里编写了详细信息部分的XML

我已经找到了解决方案，所以我把它贴在这里，所以任何遇到同样问题的人都会使用这个

尝试将您的帧设置为 位置类型=浮动
