在父页面和兄弟页面中描述的样式是静态的——PivotArea 或 CellArea 区域只会被绘制一次,无论数值如何都会保持其样式。条件格式是规则驱动的对应方式——突出显示所有大于 200 的金额、为中间 50% 的值着色,或标记排名最底的项——并且当数据透视表重新计算或刷新时,突出显示会随数值变化而更新。
在 Aspose.Cells 中,数据透视表的条件格式位于 PivotTable.ConditionalFormats 集合中。每个条目都是一个 PivotConditionalFormat,它独立回答两个问题:
ApplyTo(int row, int column, PivotConditionFormatScopeType scope) 定义,这与 Excel 用户界面的范围选择器相吻合;也可以通过 AddCellArea(CellArea) 与 PivotAreas 集合显式指定区域。FormatConditions 的 FormatConditionCollection.AddCondition(FormatConditionType type, OperatorType operatorType, String formula1, String formula2) 添加一个或多个条件,每个条件携带自己的 Style。FormatConditions 对象上调用 FormatConditionCollection.Add(CellArea cellArea, FormatConditionType type, OperatorType operatorType, String formula1, String formula2) 或 FormatConditionCollection.AddArea(CellArea)。这两个重载继承自普通工作表的条件格式 API,无法用于数据透视表——单元格区域永远不会被转换为透视区域,因此请求会被静默忽略。请始终在 PivotConditionalFormat 本身上定义区域(ApplyTo、AddCellArea 或 PivotAreas),并使用 AddCondition 系列重载之一添加规则。
第一种方式遵循 Excel 用户界面的操作方式。数据透视表的单元格使用零基工作表坐标命名,PivotConditionFormatScopeType 范围告诉 Aspose.Cells 规则应从该单元格向外扩展到多远:
PivotConditionFormatScopeType.Data - 透视表生成的所有数值单元格,包括总计。PivotConditionFormatScopeType.Field - 属于该单元格所标识字段的数值单元格,排除总计。该单元格必须是字段单元格,例如行字段标签;若传入数值单元格会抛出异常。PivotConditionFormatScopeType.Selection - 仅在该单元格选中的交叉点处的数值单元格,通常为单个数值单元格。
下面的示例创建了一个水果销售数据透视表,左上角位于 E3,将条件格式锚定在单元格 F4(第 3 行,第 5 列),使用 Data 范围,并将所有大于 200 的金额以红底白字加粗显示。给定 Apple 220、Banana 330、Cherry 200 以及总计 750,规则将覆盖 F4、F5、F7——解析后的区域为整列数据 F4:F7,仅有满足条件的单元格会被高亮。import (

将相同规则锚定在行字段标签 E4(第 3 行,第 4 列)并使用 Field 范围时,解析区域变为 F4:F6——同一数据列但不包括总计行,因为此时范围描述的是 Fruit 字段而非整个数值区域。使用 Selection 范围锚定在 F4 时,仅解析为 F4 单元格。
第二种方式跳过范围选择器,直接在 PivotConditionalFormat 上显式命名区域。
AddCellArea(CellArea) 将给定的矩形记录为规则的目标。坐标采用零基工作表坐标,区域恰好等于提供的矩形——不会自动扩展到数据列,也不会包含总计逻辑。适用于感兴趣的单元格已知为当前透视布局中的固定矩形的场景。

PivotAreas 与兄弟页面用于静态样式的语义区域模型相同。创建 PivotArea,使用 Select 或 SelectField 选择字段或区域,然后通过 PivotAreas.AddPivotArea(PivotArea) 添加。语义区域会绑定到其对应字段,因此条件格式在透视表刷新、布局变化时会随字段移动。PivotAreas.Add(PivotArea) 重载仍可编译,但已标记为过时——请优先使用 AddPivotArea。

每次调用 ConditionalFormats.Add() 都会向数据透视表追加一个 PivotConditionalFormat。条件、公式以及样式会随工作簿一起保存——在下面的示例中重新打开文件时,仍能看到同样的规则及其类型、运算符和公式完整无缺,GetCellAreas() 也会报告相同的区域。未添加任何条件的条目在工作簿保存时会被删除,这与 Excel 会丢弃没有规则的条件格式的行为一致。
