Hello people:

i have this data: {AAA , 18} ,{BBB, 10} , {CCC ,20},{DDD, 65}, …….. {SSS, 16}.
i want to show it in the report like that:

AAA    18     DDD 65    GGG 33    ………. SSS   16
BBB 10    EEE   13    …
CCC 20    FFF    98    …

Any idea? , i am using a normal table, but all the data is under , Example :

AAA 18

BBB 10

CCC 20

….

but the thing is that i have several bands, some tables, but just 1 is like the example i showed you, then i was thinking in use a subreport, what do you think?

假设源数据是 10 条双字段的记录，分栏数 colN=3，则需要生成一个 6 字段的二维表。可用 SPL 整理数据，代码较简单：

	A
1	=connect(“demo”)
2	=A1.query(“SELECT name,value FROM tb”)
3	=ceil(A2.len()/colN)
4	=A2.group(ceil(#/A3))
5	=create(${colN.(“name”/ ~ /“,value”/ ~).concat@c()}))
6	=A5.paste(${A4.len().($[A4(]/ ~ /$[).(#1),A4(]/ ~ /“).(#2)”).concat@c()})

运行结果：

A1：连接数据库

A2：查找数据

A3：计算分栏后的行数

A4：分组计算

A5：创建 name 和 value 为字段的空序表

A6：按照字段顺序，依次修改序表中的记录
