在apache poi中使用for循环

import org.apache.poi.ss.usermodel.*;

public class ApachePOIExample {
    public static void main(String[] args) {
        // 创建Workbook对象
        Workbook workbook = new XSSFWorkbook();

        // 获取Sheet对象
        Sheet sheet = workbook.createSheet("Sheet1");

        // 使用for循环遍历行
        for (int rowNum = 0; rowNum < 10; rowNum++) {
            Row row = sheet.createRow(rowNum);

            // 使用for循环遍历列
            for (int colNum = 0; colNum < 5; colNum++) {
                Cell cell = row.createCell(colNum);
                cell.setCellValue("Data " + (rowNum + 1) + "-" + (colNum + 1));
            }
        }

        // 保存Excel文档
        try {
            FileOutputStream outputStream = new FileOutputStream("output.xlsx");
            workbook.write(outputStream);
            workbook.close();
            outputStream.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
