如何避免表格重复显示两次？我想要数据 仅显示一次。
正如您在上面的屏幕截图中看到的，我不希望数据 显示两次。
您已将表格组件放入详细信息区域中。数据集中的每个记录都会重复详细信息带。你有两条记录，所以你的表重复了两次；如果你有更多的数据，你会得到更多的重复。
您可以完全摆脱表格组件，将每个columnHeader将表中的元素放入<columnHeader>乐队，以及每个detailCell元素变成<detail>乐队。这样做应该保留表组件的行为而不重复它。看http://community.jaspersoft.com/wiki/designing-report举个例子。
或者，您可以简单地将表格组件移动到不会重复的不同区域（例如<summary>).
