彩票走势图

数据透视表是一种交互式的表，可以进行某些计算，如求和与计数等。例如，您的工作表上面可能有数百条发票记录，而通过透视表，你可以根据客户，产品和日期等项目汇总发票。

Aspose.Cells是一个功能丰富的电子表格组件，支持创建数据透视表和数据透视图。Aspose.Cells提供了一些用于创建和设置数据透视表的特殊类。这些类用于创建和设置作为数据透视表基本构建模块的数据透视表对象。

数据透视表对象如下：

• PivotField：代表数据透视表中的字段
• PivotFields：代表数据透视表中的所有透视字段对象的集合
• PivotTable：代表工作表上的一个数据透视表报告
• PivotTables：代表工作表上数据透视表对象的集合

添加一个数据透视表

利用Aspose.Cells创建数据透视表，你可以按照下面的步骤：

1、使用Cell对象的PutValue/setValue方法添加数据到工作表单元格中。你也可以使用已填充了数据的现有模版文件。这些数据将被用作数据透视表的数据源。

2、添加一个数据透视表到工作表中。

3、从数据透视表集合中访问新添加的PivotTable对象。

添加一个数据透视图

使用Aspose.Cells创建一个数据透视图，您可以按照以下步骤：

1、利用Aspose.Cells API添加你想要的图表

2、设置图表的PivotSource

3、设置需要的其他属性

任务列表：

1、使用Aspose.Cells，在工作簿中创建一个数据透视表。

2、使用Aspose.Cells创建一个基于透视表的透视图。

任务1：使用Aspose.Cells，在工作簿中创建一个数据透视表

step1、下载并安装Aspose.Cells for Java。

step2、使用Eclipse 等Java编辑器或者NotePad创建一个项目。

Step3、使用Eclipse来设置类路径。

• 从Aspose.Cells.zip中获取Aspose.Cells.jar和dom4j_1.6.1.jar
• 在Eclipse中设置项目的类路径
• 选择您在Eclipse中的项目，然后点击菜单项目属性。
• 在弹出框的左侧选择 "Java Build Path"，然后选择 "Libraries" 标签，单击"Add JARs"或者"Add External JARs" 选择select Aspose.Cells.jar 和dom4j_1.6.1.jar ，并将它们添加到构建的路径中。
• 编写程序激活Aspose组件的APIs。

e.g.

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

Step4、在工作薄中创建一个数据透视表
