如何在jasper中爲子數據集中的表設置樣式條件

我希望根據條件對錶格內容進行着色。我的表存在於子數據源中，並且填充的字段來自相同的。現在我想根據一些條件對內容着色。如何在jasper中爲子數據集中的表設置樣式條件

注意：字段中的所有數據都是字符串類型。所以我開始創建一個樣式並使用我認爲在運行時從java傳遞的參數向它添加條件，它說沒有找到錯誤參數。所以我嘗試在主報告中使用字段，通過將相同的子數據源字段添加到主報告中，它說向數據字段中檢索數據失敗。我想如何檢查風格的條件。

這裏是我的代碼

如果定義在一個樣式條件表達式，你只能使用風格，其範圍。

在您的例子：

<conditionExpression><![CDATA[$F{dmScore}.equals("12")]]></conditionExpression>

的$F{dmScore}範圍是當你正在運行的subDataset="table1dataset"，因此裏面的<jr:table>標籤。

此樣式只能在此標籤範圍內使用。

解決方案：刪除超出範圍的所有樣式聲明，例如DM_STYLE。

<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>

使用參數，你可能忘了傳遞這個參數設置爲jr:table時，關於你以前的問題，因爲你在哪裏使用它裏面你有同樣的問題，但逆轉。解決方法是在subdataset中創建相同的參數，然後傳遞它。

<datasetRun subDataset="table1dataset" uuid="93792e42-02d5-4121-84a6-312310e190a0"> 
    <datasetParameter name="yourParam"> 
     <datasetParameterExpression><![CDATA[$P{yourParam}]]></datasetParameterExpression> 
    </datasetParameter> 
    <dataSourceExpression><![CDATA[new net.sf.jasperreports.engine.data.JRBeanCollectionDataSource($F{overAllSummaryReportWithOthers})]]></dataSourceExpression> 
</datasetRun>

如何在subDataset中定義樣式。糾正我，如果我錯了，樣式通常在主要報告中知道，我無法在我的jasperSoft subDataset中找到任何樣式，如何獲取子數據集中的樣式，以便我可以將我的字段用於我的條件檢查。 –

您已經正確定義了樣式（它們只在主報告中），這不是問題...問題是您只能在其上下文中使用樣式！ –

通過您傳遞的示例，刪除表標記之外的所有DM_STYLE，它將起作用。 –

如何在jasper中爲子數據集中的表設置樣式條件
