如何使用Apache POI

如何禁用使用Apache POI中间总，我用这个apache的POI禁用中间总，我想中间总应禁用如何使用Apache POI

这里是Excel输入对于理解

在Excel版本，你可以出示你预期的结果？我使用你的代码，并创建一个数据透视表，与相同的数据，并且都看起来相同（就像你当前的结果） – XtremeBaumer

谢谢，以前我们正在手动，但现在我们已经自动化这个过程，因为我发现这个apache poi图书馆，并试图用它 –

这不回答我的问题 – XtremeBaumer

就我所见，您的主要要求是摆脱小计。这可以使用org.openxmlformats.schemas.spreadsheetml.x2006.main.CTPivotField.setDefaultSubtotal(false)。

这里也询问了这个问题Apache POI XSSFPivotTable setDefaultSubtotal。

你的榜样：

import java.io.*; 

import org.apache.poi.ss.*;

    public class ApacheCreatePivotTable

     public static void main(String[] args) throws Exception

      XSSFWorkbook wb = new XSSFWorkbook(); 
      XSSFSheet sheet = (XSSFSheet) wb.createSheet(); 

      //Create some data to build the pivot table on 
      setCellData(sheet); 

      //System.out.println(sheet.getRow(0).getLastCellNum()); 

      XSSFPivotTable pivotTable = sheet.createPivotTable(new AreaReference(new CellReference(0,0),new CellReference(4,sheet.getRow(0).getLastCellNum()-1)), new CellReference(0,7)); 

      pivotTable.addRowLabel(0); 

    //set tabular layout instead of tree layout 
    pivotTable.getCTPivotTableDefinition().getPivotFields().getPivotFieldArray(0).setOutline(false); 

    /* 
    Apache poi adds 5 pivot field items of type "default" (<item t="default"/>) here. 
    This is because there are 5 rows (A1:C5) and, because they don't have a look at the data, 
    they are assuming max 5 different values. This is fine because Excel will rebuild its pivot cache while opening. 

    But if we want changing defaults, then this is not fine. Then we must know what items there are. 

    So we need at least as much items, as where different ones in the data, as numbered items: <item x="0"/><item x="1"/> 

    And we must build a cache definition which has shared elements for those items. 
    */ 


    for (int i = 0; i < 3; i++) { 
    //take the first 3 items as numbered items: <item x="0"/><item x="1"/>

    pivotTable.getCTPivotTableDefinition().getPivotFields().getPivotFieldArray(0).getItems().getItemArray(i).setX((long)i);
