简介
SpreadJS PivotTable 支持两种类型的切片器：项目切片器和时间线切片器。
与表切片器相同，枢轴切片器也通过切片器集合进行管理。
SpreadJS 定义了 SlicerType 来区分将添加哪种类型的切片器。
项目切片器可以添加到任何字段（不包括计算字段）。
在 Item Slicer 上所做的更改等同于使用手动过滤器，即标签过滤器中的 “textItems”。
时间线切片器只能添加到日期类型字段。
在时间线切片器上所做的更改等同于使用标签条件过滤器，即标签过滤器中的 “condition”。
例如，如果我们要添加数据透视表项切片器。
假设我们创建了一个名为 “pt” 的数据透视表。
如果想将项目切片器添加到 “name” 字段。
此外，假设数据透视表“pt”有一个名为 “birthday” 的日期字段，
我们想添加一个数据透视表时间线切片器。
你可能有一个问题：
很明显，项目切片器和时间线切片器可以同时添加到日期字段中。
他们可以同时工作吗？
默认情况下，不能。
它们都通过 labelFilter 工作。 设置 textItems 会导致条件过滤器丢失。
您可以通过数据透视表中的一个选项来解决此问题：allowMultipleFiltersPerField。
尝试通过单击并拖动切片器中的项目来过滤。
使用 Item Slicer，您还可以尝试在单击或拖动时按 shift 和 ctrl 键（适用于 Windows）/command 键（适用于 Mac）。
基于Shape
Pivot Slicer 是基于 Shape 的，因此您可以使用许多 Shape API 来控制 Pivot Slicer
例如
连接数据透视表
Pivot Slicer 支持管理连接，通过数据透视表添加或断开连接。
如果与数据透视表断开连接，切片器操作将不会影响数据透视表，
此外，数据透视表过滤器操作不会影响切片器。
例如，通过此功能，您可以使用切片器来管理多个相同的源数据透视表。
假设有两个数据透视表“pt1”和“pt2”，它们都是从名为“table1”的表创建的，因此它们具有相同的数据源，相同的字段。
OK，现在你可以使用 slicer_name 控制两个数据透视表的过滤器了。
