BIRT多个子组

Question

我有一个关于Birt多层次分组的问题。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具有多级分组的报告，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“拖放”和“禁止重复”。除了删除组标题之外，还无法删除单元格。该报告生成的数据如下所示，组标题上带有空单元格：

    ...etc

是否有可能像上面第二个表中那样通过删除单元格对数据进行分组？

Answer 1

1. 将column0的分组应用于column2，然后除去组头以外的所有行，并保留组头放置属性作为详细信息。
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列表达式的组中，如row [“ column0”] && row [“ column1”] && row [“ column2”] && row [“ column3”]] >。
5. 在目录中给出row [“ column0”]
6. [对列4和列5执行上述步骤。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none。
