Question

我正在使用 iReport 5.1.0 工具进行报告设计。

我的当前报告输出就像，

------------------------------------------------------------
| STUDENT_ID | SUBJECT_NAME | SUBJECT_MARK | STUDENT_NAME |
------------------------------------------------------------
|     1      |   Maths      |      25      |     John     |
------------------------------------------------------------
|     1      |   English    |      35      |     John     |
------------------------------------------------------------
|     2      |   Maths      |      30      |     James    |
------------------------------------------------------------
|     2      |   English    |      23      |     James    |
------------------------------------------------------------

但我需要类似的东西，

------------------------------------------------------------
| STUDENT_ID | SUBJECT_NAME | SUBJECT_MARK | STUDENT_NAME |
------------------------------------------------------------
|     1      |   Maths      |      25      |     John     |
             -------------------------------
|            |   English    |      35      |              |
------------------------------------------------------------
|     2      |   Maths      |      30      |     James    |
             -------------------------------
|            |   English    |      23      |              |
------------------------------------------------------------

这是我的 .jrxml 文件。

Answer 1

enter image description here 首先，您应该创建一个数据组。

1.go to report inspector
2.right click on the jrxml name at the top of the report inpector 
3.select add report group. 
4.input the group name 
5. select the object, in your case student_id from the 'group by the following report   object'
6. click next 
7. Chose add report group header or footer or both if you want to. (in your case i think you should not add report group header or footer)

您的报告组将被添加。尝试重新生成报告。您还应该取消选中“打印重复值”

在iReport工具中分组
