我使用Apache POI 3.11创建了一个数据透视表.像这样:

FileInputStream file = new FileInputStream(new File(path+fname));

XSSFWorkbook workbook = new  XSSFWorkbook(file);

XSSFSheet sheet = workbook.getSheetAt(0);
//area of pivot data
AreaReference a=new AreaReference("A1:J4");

CellReference b=new CellReference("N5");    
XSSFPivotTable pivotTable = sheet.createPivotTable(a,b);

//insert row
pivotTable.addRowLabel(3);
pivotTable.addRowLabel(6);

//insert column
pivotTable.addColumnLabel(DataConsolidateFunction.COUNT, 5);

//export
FileOutputStream output_file = 
   new FileOutputStream(new File(path+"POI_XLS_Pivot_Example.xlsx")); 
workbook.write(output_file);//write excel document to output stream
output_file.close(); //close the file

生成报告后,它会正确显示行.但它没有显示列标签:

我想在我的数据透视表中显示列标签,如下所示:

有谁知道这个问题的解决方案？

谢谢.
