Question

我对jasper报道相当新鲜。我需要在jasper表中合并单元格，并且我已经管理了它的一部分。见下图。

enter image description here

你可以看到那里有空单元格。我需要一个单元格而不是多个空单元格。你们能帮助我吗？我被卡住了。我发布了我的jrxml

Answer 1

我在这里看到两种可能的解决方案：

通过“药物名称”创建一个组乐队和组，你将有空单元格，但它看起来很酷：）
使用一些带有函数concat_ws（）的SQL功夫来获取与列表相同的字段中的“Doses Time”。

玩得开心，我希望它有所帮助。

Jasper Report在jasper表中合并单元格会导致不需要的列
