Workbook workbook = new XSSFWorkbook();
Sheet sheet = workbook.createSheet("Sheet1");

Row row1 = sheet.createRow(0);
row1.createCell(0).setCellValue("Name");
row1.createCell(1).setCellValue("Age");
row1.createCell(2).setCellValue("Gender");

Row row2 = sheet.createRow(1);
row2.createCell(0).setCellValue("John");
row2.createCell(1).setCellValue(25);
row2.createCell(2).setCellValue("Male");

Row row3 = sheet.createRow(2);
row3.createCell(0).setCellValue("Jane");
row3.createCell(1).setCellValue(30);
row3.createCell(2).setCellValue("Female");

CellRangeAddress sourceDataRange = new CellRangeAddress(0, 2, 0, 2);
AreaReference sourceDataReference = new AreaReference(sourceDataRange, SpreadsheetVersion.EXCEL2007);

CellReference pivotTableLocation = new CellReference("E5");
XSSFPivotTable pivotTable = sheet.createPivotTable(sourceDataReference, pivotTableLocation);

pivotTable.addRowLabel(0); // 将第一列作为行标签
pivotTable.addColumnLabel(DataConsolidateFunction.SUM, 1); // 将第二列作为求和值
pivotTable.addColumnLabel(DataConsolidateFunction.AVERAGE, 1); // 将第二列作为平均值

FileOutputStream outputStream = new FileOutputStream("pivot_example.xlsx");
workbook.write(outputStream);
workbook.close();
outputStream.close();
