如何使用POI Apache将工作表从Excel文件单元格弹出文档复制到另一文档？

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

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;

public class ExcelCopyExample {
    public static void main(String[] args) {
        String sourceFilePath = "source.xlsx";
        String targetFilePath = "target.xlsx";

        try (FileInputStream fis = new FileInputStream(sourceFilePath);
             Workbook sourceWorkbook = WorkbookFactory.create(fis);
             Workbook targetWorkbook = WorkbookFactory.create(true)) {

            Sheet sourceSheet = sourceWorkbook.getSheetAt(0);
            Sheet targetSheet = targetWorkbook.createSheet();

            for (Row sourceRow : sourceSheet) {
                Row targetRow = targetSheet.createRow(sourceRow.getRowNum());

                for (Cell sourceCell : sourceRow) {
                    Cell targetCell = targetRow.createCell(sourceCell.getColumnIndex());
                    targetCell.setCellValue(getCellValue(sourceCell));
                }
            }

            try (FileOutputStream fos = new FileOutputStream(targetFilePath)) {
                targetWorkbook.write(fos);
            }

            System.out.println("Excel sheet copied successfully!");

        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    private static String getCellValue(Cell cell) {
        String cellValue = "";

        if (cell.getCellType() == CellType.STRING) {
            cellValue = cell.getStringCellValue();
        } else if (cell.getCellType() == CellType.NUMERIC) {
            cellValue = String.valueOf(cell.getNumericCellValue());
        } else if (cell.getCellType() == CellType.BOOLEAN) {
            cellValue = String.valueOf(cell.getBooleanCellValue());
        }

        return cellValue;
    }
}
