报告中具有预定义列数

标签： jasper-reports

我正在尝试在jasper报告中逐列显示数据以实现相同的目标我创建了具有A4大小的jasper报告，并将页面属性垂直更改为3列，以便在3列中垂直显示数据。

问题是如果我有一条记录然后它显示正确的数据，但如果我有多个数据然后它打印出现有数据的数据，我不想要有任何方式我们可以强迫jasper并行显示数据另一种是垂直方式，而不是相互打印。

下面是我用于插入语句测试目的的示例表。

 create table jasper_demo(  
  no         number(2,0),  
  name       varchar2(14),  
  loc        varchar2(13)  
 )

 insert into jasper_demo values(10, 'ACCOUNTING', 'NEW YORK');

 insert into jasper_demo values(20, 'INFLATION', 'LONDON');

 insert into jasper_demo values(30, 'GAMMA-RAYS', 'CHINA');

 insert into jasper_demo values(40, 'HEXA-RAYS', 'JAPAN');

从db（oracle 11g）

检索数据的查询 
SELECT
b.no,b.name,b.loc
FROM
(SELECT LEVEL  as lvl from dual CONNECT BY LEVEL <= 24)
 a
full outer JOIN
(  SELECT    rownum  as lvl,
      no,
      name,
      loc
     from jasper_demo 
  )   b ON a.lvl = b.lvl
order by a.lvl

我面临的问题：

This is the screen shot of wrong display

1 个答案:

答案 0 :(得分：3)

报告的设计是错误的。

Wrong design

正确的＆＃34;列＆＃34;有三个textFields超出了列的区域。

您已为报告设置此属性：

  • =信息columnCount＆＃34; 3＆＃34;
  • pageWidth =＆＃34; 595＆＃34;
  • columnWidth时=＆＃34; 185＆＃34;

并且textFields从第二（右）列的x位置的宽度大于 185 。

修复非常简单。您应该为textField设置所有元素都在列的大小和位置。

良好设计的样本

模板

所有元素都位于报告栏的区域。

Right design

数据源

我使用过简单的 csv 数据源：

category,user,status
1,user1,WORK
1,user1,HOLIDAY
1,user2,SICK
2,user1,WORK
2,user2,WORK
2,user2,HOLIDAY
2,user3,HOLIDAY
2,user4,SICK
3,user1,HOLIDAY
3,user3,HOLIDAY
3,user5,HOLIDAY
4,user1,WORK
4,user1,HOLIDAY
4,user2,SICK
4,user2,WORK
4,user2,SICK
4,user3,HOLIDAY
4,user4,HOLIDAY
4,user5,HOLIDAY

输出结果

输出结果是每行3列（一列有两个textFields） - 每个伪行有6列textFields。

Output result at JSS

重叠效应消失了。
