我希望我的表内容根据条件进行着色。我的表存在于子数据源中，并且填充的字段来自相同的字段。现在我想根据一些条件给内容上色。
注意：字段中的所有数据都属于字符串类型。所以我开始创建一个样式，并使用我想在运行时从java传递的参数为其添加一个条件，它说找不到一个错误参数。因此，我尝试在主报告中使用Fields，将子数据源的相同字段添加到主报告中，它表示检索字段的数据失败。我该如何检查样式中的条件。
这是我的代码

如果在样式上定义条件表达式，则只能在其范围内使用该样式。
在您的示例中：
<conditionExpression><![CDATA[$F{dmScore}.equals("12")]]></conditionExpression>
$F{dmScore}的作用域是在运行subDataset="table1dataset"时，因此位于<jr:table>标记内部。
此样式只能在此标记范围内使用。
解决方案：例如，删除DM_style的所有超出范围的样式声明。
<reportElement style="DM_STYLE" x="4" y="130" width="554" height="80" uuid="a9101195-3ec3-4fcd-acdd-f4f0665b9c5b">
<property name="com.jaspersoft.studio.layout" value="com.jaspersoft.studio.editor.layout.VerticalRowLayout"/>
</reportElement>
关于之前使用参数时的问题，您可能忘记将此参数传递给jr:table，并且由于您在内部使用它，所以出现了相同的问题，但发生了逆转。这个问题的解决方案是在subdataset中创建相同的参数，然后传递它
<datasetRun subDataset="table1dataset" uuid="93792e42-02d5-4121-84a6-312310e190a0">
<datasetParameter name="yourParam">

</datasetParameter>
