数据透视表切片器

概述本 Demo 展示了数据透视表切片器的完整功能，包括项目切片器和时间线切片器的创建、属性配置和交互操作。Demo 中创建了两个数据透视表和五个切片器，并提供了交互面板来动态修改切片器的属性和连接状态。实现思路初始化数据源工作表，加载销售数据表创建两个数据透视表：pt1 按地区、国家、城市分组，pt2 按日期分组为 pt2 创建两个时间线切片器（年份和月份）为 pt1 创建三个项目切片器（地区、国家、城市）配置切片器的位置、大小、样式等属性绑定交互事件，允许用户选中切片器后修改其属性提供连接/断开数据透视表的功能代码解析创建数据透视表这段代码创建了第一个数据透视表 pt1，使用地区、国家、城市作为行字段，金额作为值字段。添加时间线切片器使用 slicers.add() 方法创建时间线切片器，参数包括切片器名称、关联的数据透视表名称、字段名称、样式和类型。时间线切片器使用 SlicerType.pivotTimeline 类型，并通过 level() 方法设置时间粒度。添加项目切片器项目切片器使用 SlicerType.pivotTable 类型。columnCount() 方法设置显示列数，showHeader() 控制是否显示标题。管理切片器连接切片器可以连接多个具有相同数据源的数据透视表，实现跨表筛选。连接后，切片器的筛选操作会同步影响所有连接的数据透视表。运行效果页面左侧显示两个数据透视表，分别按地区和日期分组右侧显示五个切片器，包括两个时间线切片器和三个项目切片器点击切片器中的项目可以对数据透视表进行筛选点击选中切片器后，右侧面板显示切片器的属性信息可以在面板中修改切片器的名称、标题、位置和大小可以通过复选框控制切片器与数据透视表的连接状态按住 Ctrl 键（Windows）或 Command 键（Mac）点击可选择多个项目 API 参考 slicers.add() 方法 slicerName: 切片器名称 targetName: 关联的数据透视表名称 itemName: 关联的字段名称 style: 切片器样式（SlicerStyle 或 TimelineStyle） type: 切片器类型（SlicerType.pivotTable 或 SlicerType.pivotTimeline）切片器属性方法 position({x, y}): 设置位置 width(value): 设置宽度 height(value): 设置高度 columnCount(value): 设置列数（项目切片器） level(value): 设置时间级别（时间线切片器） captionName(value): 设置标题名称
