如何防止在交叉表的行组（列）中加入值？
How to prevent joining values in Row Group (column) of Crosstab?
有没有办法取消合并交叉表中具有相同值的单元格？
问题是相同值的单元格正在合并。
我想要重复值并有单元格边框。例如，在一个行组中，如果我有 2 列，col1 的值为 'abc'，col2 的值为 1,2,3，如果有 3 行，则 col1 是一个大单元格 'abc'只打印一次。
这是我不想要的，而是希望它打印 3 次。
这是我需要的演示文稿：

中的col1和col2您的示例是 行组 。这个名称 (Row Group) 告诉我们 JasperReports 引擎联合所有 non unique 值以防万一使用 Crosstab 组件。这就是为什么应该始终对值进行排序以正确分组数据（如下图所示）。
行组中的数据将按JR引擎分组，一组作为一个单元格绘制.
Does this mean that the problem has no solution? - 不行，我们来解决！
看起来您需要 "to join" col1 和 col2 列值。这意味着 col1 Row Group 的值可以添加到 col2 Row Group 的 "column" 中。
例子
数据源
用简单的 csv 数据源来测试样本就足够了。
col1,col2,col3,col4,col5
abcd,1,b,1c,434
abcd,2,c,2c,333
abcd,3,c,4c,333
abcd,3,c,4c,333
abcd,5,c,4c,333
abcd,3,e,3g,909
下例中此数据源的数据适配器名称为values.csv。文件的第一行被跳过 - 它包含列的名称。
报告模板
我们应该将第一列 (col1 行组) 的宽度设置为零，并增加第二列 (col2 行组) 添加 col1 的值。在这种情况下，JR 引擎 为每个唯一的 col2 值绘制两个值。我们仍然需要第一列，因为我们需要 col1 的值（col1 行组 的存储桶）。

中的col1和col2您的示例是 行组 。这个名称 (Row Group) 告诉我们 JasperReports 引擎联合所有 non unique 值以防万一使用 Crosstab 组件。这就是为什么应该始终对值进行排序以正确分组数据（如下图所示）。
行组中的数据将按JR引擎分组，一组作为一个单元格绘制.
Does this mean that the problem has no solution? - 不行，我们来解决！
看起来您需要 "to join" col1 和 col2 列值。这意味着 col1 Row Group 的值可以添加到 col2 Row Group 的 "column" 中。
例子
数据源
用简单的 csv 数据源来测试样本就足够了。
col1,col2,col3,col4,col5
abcd,1,b,1c,434
abcd,2,c,2c,333
abcd,3,c,4c,333
abcd,3,c,4c,333
abcd,5,c,4c,333
abcd,3,e,3g,909
下例中此数据源的数据适配器名称为values.csv。文件的第一行被跳过 - 它包含列的名称。
报告模板
我们应该将第一列 (col1 行组) 的宽度设置为零，并增加第二列 (col2 行组) 添加 col1 的值。在这种情况下，JR 引擎 为每个唯一的 col2 值绘制两个值。我们仍然需要第一列，因为我们需要 col1 的值（col1 行组 的存储桶）。
