数据透视表过滤器

概述本 Demo 展示了如何为数据透视表设置标签过滤器和值过滤器。Demo 创建了一个销售数据透视表，用户可以通过界面控件选择不同的过滤条件和操作符，动态筛选数据透视表中显示的内容。实现思路创建数据源表，包含销售数据（日期、销售人员、汽车、数量、单价、总额）创建数据透视表，添加销售人员、汽车作为行字段，季度作为列字段，数量作为值字段对日期字段进行分组，按季度显示绑定界面按钮事件，实现标签过滤器和值过滤器的设置与清除支持多种过滤操作符（等于、不等于、大于、小于、介于等）代码解析创建数据透视表创建数据透视表并添加字段：销售人员作为行字段，汽车作为行字段，日期按季度分组后作为列字段，数量作为值字段进行求和汇总。设置标签过滤器标签过滤器根据字段标签进行筛选。labelFilter 方法接收字段名和过滤条件对象，conType 设置为 caption 表示标签过滤，operator 使用界面选择的操作符索引，val 数组包含一个或两个过滤值。设置值过滤器值过滤器根据汇总值进行筛选。conditionByName 指定用于比较的汇总值字段名称，这里根据"数量"字段的汇总值来过滤"销售人员"字段。conType 设置为 value 表示值过滤。清除过滤器将过滤条件参数设置为 null 即可清除对应的过滤器。运行效果页面左侧显示数据透视表，右侧显示过滤控制面板标签过滤器提供 14 种操作符（等于、不等于、以…开头、包含、大于、介于等）值过滤器提供 8 种操作符（等于、大于、小于、介于等）点击"设置标签筛选器"按钮，根据输入的条件过滤销售人员字段点击"设置值筛选器"按钮，根据数量汇总值过滤销售人员字段点击"清除"按钮移除对应的过滤条件，恢复显示所有数据所有过滤操作都会实时更新数据透视表显示 API 参考 labelFilter 方法 fieldName：要过滤的字段名称 filterInfo.condition.conType：条件类型，GC.Pivot.PivotConditionType.caption 表示标签过滤 filterInfo.condition.val：过滤值数组，单值操作符传入一个值，双值操作符（如介于）传入两个值 filterInfo.condition.operator：操作符索引，对应界面下拉列表的选项设置为 null 时清除过滤器 valueFilter 方法 fieldName：要过滤的字段名称 filterInfo.condition.conType：条件类型，GC.Pivot.PivotConditionType.value 表示值过滤 filterInfo.condition.val：过滤值数组 filterInfo.condition.operator：操作符索引 filterInfo.conditionByName：用于比较的汇总值字段名称设置为 null 时清除过滤器
