excel Apache POI Pivot表如何在Java中使用“中间”值过滤器
我正在尝试使用ApachePOI设计一个透视表，我想做的是首先打印大于某个数字的和值，以及小于某个数字的和值。然而，当我尝试这样做时，过滤器会相互抵消，这意味着打印的和值不应该存在。例如，如果我希望和在2到5之间，和值1以及大于5的数字都会被打印出来。下面是解释我的问题的代码：

这是由于运行以下代码而打印的透视表：

那么，如何获得需要为
*.xlsx文件设置的内容呢？*.xlsx只是一个ZIP存档。所以你可以把*.xlsx解压，看看里面是什么所以，使用
Excel的GUI来做你需要做的事情，保存*.xlsx，然后解压并查看/xl/pivotTables/pivotTable1.xml。在这里，您可以找到以下过滤器设置：所以
customFilters需要设置以下过滤器是AND链接的。这是您的代码尚未设置的内容完整示例：
