BIRT多个子组

Question

我有一个关于birt多级分组的问题。我有一个返回以下内容的数据集：

    +---------+---------+---------+---------+---------+---------+
    | Column0 | Column1 | Column2 | Column3 | Column4 | Column5 |
    +---------+---------+---------+---------+---------+---------+
    | Data00  | Data11  | Data21  | Data    | Data    | Data    |
    +---------+---------+---------+---------+---------+---------+
    | Data00  | Data11  | Data21  | Data    | Data    | Data    |
    +---------+---------+---------+---------+---------+---------+
    | Data00  | Data11  | Data22  | Data    | Data    | Data    |
    +---------+---------+---------+---------+---------+---------+
    | Data00  | Data11  | Data22  | Data    | Data    | Data    |
    +---------+---------+---------+---------+---------+---------+
    | Data00  | Data12  | Data23  | Data    | Data    | Data    |
    +---------+---------+---------+---------+---------+---------+
    | Data00  | Data12  | Data23  | Data    | Data    | Data    |
    +---------+---------+---------+---------+---------+---------+
    | Data00  | Data12  | Data23  | Data    | Data    | Data    |
    +---------+---------+---------+---------+---------+---------+
    | Data00  | Data12  | Data23  | Data    | Data    | Data    |
    +---------+---------+---------+---------+---------+---------+

现在我需要创建一个包含多级分组的报告，该报告将给出如下所示的结果：

    +---------+---------+---------+---------+---------+---------+
    | Column0 | Column1 | Column2 | Column3 | Column4 | Column5 |
    +---------+---------+---------+---------+---------+---------+
    | Data00  | Data11  | Data21  | Data    | Data    | Data    |
    +         +         +         +---------+---------+---------+
    |         |         |         | Data    | Data    | Data    |
    +         +         +---------+---------+---------+---------+
    |         |         | Data22  | Data    | Data    | Data    |
    +         +         +         +---------+---------+---------+
    |         |         |         | Data    | Data    | Data    |
    +         +---------+---------+---------+---------+---------+
    |         | Data12  | Data23  | Data    | Data    | Data    |
    +         +         +         +---------+---------+---------+
    |         |         |         | Data    | Data    | Data    |
    +         +         +         +---------+---------+---------+
    |         |         |         | Data    | Data    | Data    |
    +         +         +         +---------+---------+---------+
    |         |         |         | Data    | Data    | Data    |
    +---------+---------+---------+---------+---------+---------+

我已经尝试过“Drop”和“Suppress duplicates”。除了删除组头之外，不可能的单元格也会丢失。该报告生成如下所示的数据，并在组标题上显示空单元格：

    ...

    ...etc

是否可以像上面的第二个表一样使用丢弃单元格对数据进行分组？

Answer 1

1. 将column0的分组应用于column2，然后删除除组头之外的所有行，并保留组头放置属性为详细信息。
2. 对于具有1行1列的数据单元格插入表中的column3。
3. 在该表插入组内。
4. 在表达式组中为第3列的所有列提供“和条件”。在第3列表达式中的组，例如 row [“ column0”] && row [“ column1”] && row [“ column2”] && row [“ column3” ] 。
5. 在目录中给出行[“ column0”]
6. 按照上述步骤对column4和column5进行操作。删除表中除组头以外的其他行，并将column3的组头的drop属性保留为column5为空。
