• Java使用POI操作Excel合并单元格


    合并单元格的方法:
    指定 4 个参数,起始行,结束行,起始列,结束列。然后这个区域将被合并。

    CellRangeAddress region = new CellRangeAddress(startRow, endRow, startCol, endCol);
    sheet.addMergedRegion(region);
    合并的简单示例:

    public class TestExcel {

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

    HSSFWorkbook workbook = new HSSFWorkbook();

    HSSFCellStyle style = workbook.createCellStyle();
    style.setAlignment(HSSFCellStyle.ALIGN_CENTER);
    style.setVerticalAlignment(HSSFCellStyle.VERTICAL_CENTER);

    HSSFSheet sheet = workbook.createSheet("sheet");

    HSSFRow row0 = sheet.createRow(0);
    HSSFCell cell_00 = row0.createCell(0);
    cell_00.setCellStyle(style);
    cell_00.setCellValue("日期");
    HSSFCell cell_01 = row0.createCell(1);
    cell_01.setCellStyle(style);
    cell_01.setCellValue("午别");

    HSSFRow row1 = sheet.createRow(1);
    HSSFCell cell_10 = row1.createCell(0);
    cell_10.setCellStyle(style);
    cell_10.setCellValue("20180412");
    HSSFCell cell_11 = row1.createCell(1);
    cell_11.setCellStyle(style);
    cell_11.setCellValue("上午");

    HSSFRow row2 = sheet.createRow(2);
    HSSFCell cell_21 = row2.createCell(1);
    cell_21.setCellStyle(style);
    cell_21.setCellValue("下午");

    // 合并日期占两行(4个参数,分别为起始行,结束行,起始列,结束列)
    // 行和列都是从0开始计数,且起始结束都会合并
    // 这里是合并excel中日期的两行为一行
    CellRangeAddress region = new CellRangeAddress(1, 2, 0, 0);
    sheet.addMergedRegion(region);

    File file = new File("E:\\demo.xls");
    FileOutputStream fout = new FileOutputStream(file);
    workbook.write(fout);
    fout.close();
    }

    }

    运行结果,得到的 Excel 表如下所示:



    当然也可以更复杂些的,如下图,需要自己计算好行与列即可
