數據透視表是一種交互式的表，可以進行某些計算，如求和與計數等。例如，您的工作表上面可能有數百條發票記錄，而通過透視表，你可以根據客戶，產品和日期等項目匯總發票。

Aspose.Cells是一個功能豐富的電子表格組件，支持創建數據透視表和數據透視圖。Aspose.Cells提供了一些用于創建和設置數據透視表的特殊類。這些類用于創建和設置作為數據透視表基本構建模塊的數據透視表對象。

數據透視表對象如下：

• PivotField：代表數據透視表中的字段
• PivotFields：代表數據透視表中的所有透視字段對象的集合
• PivotTable：代表工作表上的一個數據透視表報告
• PivotTables：代表工作表上數據透視表對象的集合

添加一個數據透視表

利用Aspose.Cells創建數據透視表，你可以按照下面的步驟：

1、使用Cell對象的PutValue/setValue方法添加數據到工作表單元格中。你也可以使用已填充了數據的現有模版文件。這些數據將被用作數據透視表的數據源。

2、添加一個數據透視表到工作表中。

3、從數據透視表集合中訪問新添加的PivotTable對象。

添加一個數據透視圖

使用Aspose.Cells創建一個數據透視圖，您可以按照以下步驟：

1、利用Aspose.Cells API添加你想要的圖表

2、設置圖表的PivotSource

3、設置需要的其他屬性

任務列表：

1、使用Aspose.Cells，在工作簿中創建一個數據透視表。

2、使用Aspose.Cells創建一個基于透視表的透視圖。

任務1：使用Aspose.Cells，在工作簿中創建一個數據透視表

step1、下載并安裝Aspose.Cells for Java。

step2、使用Eclipse 等Java編輯器或者NotePad創建一個項目。

Step3、使用Eclipse來設置類路徑。

• 從Aspose.Cells.zip中獲取Aspose.Cells.jar和dom4j_1.6.1.jar
• 在Eclipse中設置項目的類路徑
• 選擇您在Eclipse中的項目，然后點擊菜單項目屬性。
• 在彈出框的左側選擇 "Java Build Path"，然后選擇 "Libraries" 標簽，單擊"Add JARs"或者"Add External JARs" 選擇select Aspose.Cells.jar 和dom4j_1.6.1.jar ，并將它們添加到構建的路徑中。
• 編寫程序激活Aspose組件的APIs。

e.g.

javac -classpath %classpath%;e:\Aspose.Cells.jar; ClassName .javajava -classpath %classpath%;e:\Aspose.Cells.jar; ClassName

Step4、在工作薄中創建一個數據透視表
