我正在尝试使用Apache POI设计数据透视表,而我想要做的是首先打印出大于一定数量且小于一定数量的总和值。但是,当我尝试执行此操作时,过滤器会相互抵消,这意味着将打印不应该存在的总和值。例如,如果我希望总和在2到5之间,则总和值为1以及大于5的数字都将被打印出来。这是解释我的问题的代码:

那么,如何获取*.xlsx
文件需要设置的内容? *.xlsx
只是ZIP
存档。因此,您可以解压缩*.xlsx
并查看其中的内容。
使用Excel
的{{1}}执行所需操作,保存GUI
,然后解压缩并查看*.xlsx
。在那里,您将找到以下过滤器设置:
/xl/pivotTables/pivotTable1.xml
因此,<filters count="1">
<filter fld="1" type="valueBetween" evalOrder="-1" id="1" iMeasureFld="0">
<autoFilter ref="A1">
<filterColumn colId="0">
<customFilters and="1">
<customFilter operator="greaterThanOrEqual" val="2"/>
<customFilter operator="lessThanOrEqual" val="5"/>
</customFilters>
</filterColumn>
</autoFilter>
</filter>
</filters>
需要设置为customFilters
链接了以下过滤器。这是您的代码尚未设置的内容。
