Question

我在Cross选项卡中有一个Column测量值，当列值发生变化时，需要对其进行不同的样式设置。对于实例，我当前的输出看起来像这样

我试图以这种方式为列着色

此处的输出格式为xls。

SHIPCITY是一个父列标题，在该标题下面有SHIPADRESS。

下面是生成当前输出的jrxml。您可以使用它重现问题。

我可以创建两个条件，但无法想到在条件表达式中应用的逻辑。关于如何实现这种条件造型的任何想法？

Answer 1

这很棘手。我在我的SQL中添加了一个用于着色的列。使用dense_rank（）函数我给结果排名并将它们分组在国家名称上。所以基本上那些具有相同国家名称的行具有相同的排名，然后我根据国家名称对此进行排序。

在碧玉一边。我在列组中添加了这个着色列，并将其宽度设置为零，然后将条件样式逻辑添加到奇数和偶数值。这是我正在寻找的逻辑。

当值相对于前一列值发生变化时，如何更改列的背面颜色。（条件样式）
