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

String[][] data = {
    {"A1", "B1", "C1"},
    {"A2", "B2", "C2"},
    {"A3", "B3", "C3"}
};

for (int col = 0; col < data[0].length; col++) {
    XSSFRow row = sheet.createRow(0); // 创建新行
    for (int rowIdx = 0; rowIdx < data.length; rowIdx++) {
        XSSFCell cell = row.createCell(col); // 创建新单元格
        cell.setCellValue(data[rowIdx][col]); // 设置单元格的值
    }
}

try (FileOutputStream outputStream = new FileOutputStream("path/to/excel.xlsx")) {
    workbook.write(outputStream);
}
