我目前正在研究将数据从一个 Excel 工作表复制到另一个工作簿的概念，如果存在空白单元格，则应将其复制到输出文件。下面是输入文件的屏幕截图：

这是我执行复制功能的代码

import org.apache.poi.*;
import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.CellType;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.ss.usermodel.Row.MissingCellPolicy;
import org.apache.poi.ss.usermodel.Sheet;
import org.apache.poi.xssf.usermodel.XSSFCell;
import org.apache.poi.xssf.usermodel.XSSFRow;
import org.apache.poi.xssf.usermodel.XSSFSheet;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
import org.apache.poi.xssf.usermodel.examples.CreateCell;

public class openwb_test {


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

        File inputFile=new File("input.xlsx");
        FileInputStream fis=new FileInputStream(inputFile);
        XSSFWorkbook inputWorkbook=new XSSFWorkbook(fis);
        int inputSheetCount=inputWorkbook.getNumberOfSheets();
        System.out.println("Input sheetCount: "+inputSheetCount);


        File outputFile=new File("output.xlsx");
        FileOutputStream fos=new FileOutputStream(outputFile);


        XSSFWorkbook outputWorkbook=new XSSFWorkbook();


        for(int i=0;i<inputSheetCount;i++) 
        { 
            XSSFSheet inputSheet=inputWorkbook.getSheetAt(i); 
            String inputSheetName=inputWorkbook.getSheetName(i); 
            XSSFSheet outputSheet=outputWorkbook.createSheet(inputSheetName); 


            copySheet(inputSheet,outputSheet); 
        }


        outputWorkbook.write(fos); 

        fos.close(); 

        outputWorkbook.close();
    } …
