java excel合并单元格

要在Java中合并Excel单元格，您可以使用Apache POI库。以下是一个示例代码，演示如何使用Java合并Excel单元格。

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

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

public class MergeCellsExample {
    public static void main(String[] args) throws IOException {
        // 创建一个新的工作簿
        Workbook workbook = new XSSFWorkbook();

        // 创建一个工作表
        Sheet sheet = workbook.createSheet("Sheet1");

        // 合并单元格
        CellRangeAddress mergedRegion = new CellRangeAddress(0, 0, 0, 3);
        sheet.addMergedRegion(mergedRegion);

        // 创建合并后的单元格
        Row row = sheet.createRow(0);
        Cell cell = row.createCell(0);
        cell.setCellValue("合并后的单元格");

        // 保存工作簿
        FileOutputStream fileOut = new FileOutputStream("合并单元格.xlsx");
        workbook.write(fileOut);
