创建数据透视表和数据透视图

数据透视表是记录的互动摘要。例如,您可能有数百个工作表中列表中的发票条目。数据透视表可以按客户、产品或日期总计发票。使用Microsoft Excel,可以通过将按钮拖到新位置,快速重新排列数据透视表中的信息。
数据透视图图表是数据透视表中数据的交互式图形表示。数据透视图图表在Excel 2000中引入。使用数据透视图图表使数据更容易理解,因为数据透视表会自动创建小计和总计。
添加数据透视表和数据透视图
Aspose.Cells 提供了一组特殊的类,用于创建数据透视表。这些类用于创建和设置 PivotTable 对象,作为数据透视表对象的基本构建快:
- PivotField,数据透视表报告中的字段。
- PivotFields,数据透视表中所有 PivotField 对象的集合。
- 一个工作表上的数据透视表。
- 数据透视表是工作表上所有数据透视表对象的集合。
准备使用Aspose.Cells
- 下载并安装 Aspose.Cells:
- 下载 Aspose.Cells。
- 在您的开发计算机上安装它。 所有Aspose组件在安装后均处于评估模式。 评估模式没有时间限制,只会在生成的文档中添加水印。若要充分发挥组件的功能,您需要有有效的许可证。
- 创建一个项目:
- 启动 Visual Studio.Net。
- 创建新的控制台应用程序。
- 添加引用: 将Aspose.Cells组件的引用添加到项目中,例如…\ Program Files\ Aspose\ Aspose.Cells\ Bin\ Net1.0\ Aspose.Cells.dll
添加数据透视表
使用Aspose.Cells创建数据透视表:
- 使用Cell对象的PutValue/setValue方法向工作表单元格添加一些数据。您还可以使用已填充数据的模板文件。这些数据将用作数据透视表的数据源。
- 通过调用PivotTables集合的add方法(封装在Worksheet对象中)向工作表添加一个数据透视表。
- 通过传入索引从PivotTables集合中访问新的 PivotTable 对象。# 使用 PivotTable 对象中封装的任何数据透视表对象来管理表。

添加数据透视图
使用Aspose.Cells创建数据透视图:
- 添加图表。
- 将图表的数据源设置为引用电子表格中的现有数据透视表。
- 设置其他属性。
