java怎么操作excel合并单元格

利用java操作Excel源东东－jxl.jar读取前单元格值 String cellValue = cells[k].getContents(); sb.append(cellValue+" "); } } sb.append("

"); } sb.append("

"); } } //关闭资源释放内存 wb.close(); return sb.toString(); } 二.写入Excel文件格式比文本内容加粗加某些颜色等参考jxlapi同推荐篇错文章：/developerworks/cn/java/l-javaExcel/?ca=j-t10java 代码public static void writeExcel(String fileName){ WritableWorkbook wwb = null; try { //首先要使用Workbook类工厂创建写入工作薄(Workbook)象 wwb = Workbook.createWorkbook(new File(fileName)); } catch (IOException e) { e.printStackTrace(); } if(wwb!=null){ //创建写入工作表 //WorkbookcreateSheet两参数第工作表名称第二工作表工作薄位置 WritableSheet ws = wwb.createSheet("sheet1", 0); //面始添加单元格 for(int i=0;i0){ //每工作表进行循环 for(int i=0;iif(breakSheet) break; //前工作表行数 int rowNum = sheet[i].getRows(); boolean breakRow = false; for(int j=0;jif(breakRow) break; //前行所单元格 Cell[] cells = sheet[i].getRow(j); if(cells!=nullcells.length0){ boolean breakCell = false; //每单元格进行循环 for(int k=0;kif(breakCell) break; //读取前单元格值 String cellValue = cells[k].getContents(); if(cellValue==null) continue; if(cellValue.contains(keyWord)){ res = true; breakCell = true; breakRow = true; breakSheet = true; } } } } } } //关闭资源释放内存 wb.close(); return res; } 四.往Excel插入图片图标插入图片实现容易参看代码：java 代码public static void insertImg(WritableSheet dataSheet, int col, int row, int width, int height, File imgFile){ WritableImage img = new WritableImage(col, row, width, height, imgFile); dataSheet.addImage(img); } 代码注释已经清楚概用再解释我用程序验证：java 代码try { //创建工作薄 WritableWorkbook workbook = Workbook.createWorkbook(new File("D:/test1.xls")); //待插入工作表 WritableSheet imgSheet = workbook.createSheet("Images",0); //要插入图片文件 File imgFile = new File("D:/1.png"); //图片插入第二行第单元格宽各占六单元格 insertImg(imgSheet,0,1,6,6,imgFile); workbook.write(); workbook.close(); catch (IOException e) { e.printStackTrace(); catch (WriteException e) { e.printStackTrace(); jxl支持png格式图片jpg格式gif格式都支持五.插入页眉页脚般页眉页脚都三部,左,,右三部,利用代码实现插入页眉页脚java 代码public static void setHeader(WritableSheet dataSheet,String left,String center,String right){ HeaderFooter hf = new HeaderFooter(); hf.getLeft().append(left); hf.getCentre().append(center); hf.getRight().append(right); //加入页眉 dataSheet.getSettings().setHeader(hf); //加入页脚 //dataSheet.getSettings().setFooter(hf); } 我用代码测试该:java 代码try { //创建工作薄 WritableWorkbook workbook = Workbook.createWorkbook(new File("D:/test1.xls")); //待插入工作表 WritableSheet dataSheet = workbook.createSheet("加入页眉",0); ExcelUtils.setHeader(dataSheet, "chb", "2007-03-06", "第1页,共3页"); workbook.write(); workbook.close(); } catch (IOException e) { e.printStackTrace(); } catch (WriteException e) { e.printStackTrace(); } } 合并单元格：//首先创建sheetWritableSheet sheetWrite=writeWorkbook.createSheet("sheet名称",0);// 单元格（column, row）单元格（column1, row1）进行合并sheetWrite.mergeCells(column, row, column1, row1);java 操作exceljxl加边框jxl合并单元格,单元格设置单元WritableCellFormat headerFormat = new WritableCellFormat(HEADER_FONT_STYLE);//水平居齐headerFormat.setAlignment(Alignment.CENTRE);//竖直向居齐headerFormat.setVerticalAlignment(VerticalAlignment.CENTRE);//建立标签参数依：列索引、行索引、内容、格式Label seqLabel = new Label(0, 0, "序号", headerFormat);//增加单元格sheet.addCell(seqLabel);//合并单元格参数依：列索引、行索引、列索引+需要合并列数、行索引+需要合并行数sheet.mergeCells(0, 0, 0, 1);//设置单元格宽度字符单位sheet.setColumnView(0, "序号".length() + 10);Label basicInfoLabel = new Label(1, 0, "基本信息",headerFormat);sheet.addCell(basicInfoLabel);sheet.mergeCells(1, 0, 3, 0);//合并垮3行sheet.mergeCells(1, 1, 1, 3);//合并垮3列label = new Label(0, 1, "苹);sheet.mergeCells(0,1, 0, 3- 1);//合并垮3列WritableCellFormat cellFormat = new WritableCellFormat();cellFormat.setVerticalAlignment(VerticalAlignment.CENTRE);// 垂直居label.setCellFormat(cellFormat);sheet.addCell(label);注：再使cellFormat需要重新NEW WritableCellFormatjava怎么操作excel合并单元格

有关java通过poi处理excle中合并单元格的问题

难点是：第一个单元格为合并单元格，不知道怎么与第二，第三级菜单对应

方案一：将合并的单元格还原

步骤：

1.获取合并区域，将合并区域还原，并且还原后的值为之前合并区域值内容。

2.重新按照行读取即可以。

创建数组做映射，无需生成文件

private void decodeMergeCell(HSSFSheet templateSheet) {

int numMerge = templateSheet.getNumMergedRegions();

CellRangeAddress region = null;

while(numMerge 0){

region = templateSheet.getMergedRegion(0);

if (region.getFirstColumn() == 0 || region.getFirstColumn() == 1) {

HSSFRow row = templateSheet.getRow(region.getFirstRow());

HSSFCell cell = row.getCell(region.getFirstColumn());

String value = cell.getStringCellValue();

templateSheet.removeMergedRegion(0);

for (int j = region.getFirstRow(); j =region.getLastRow(); j++) {

cell = templateSheet.getRow(j).getCell(

region.getFirstColumn());

cell.setCellValue(value);

}

}

numMerge = templateSheet.getNumMergedRegions();

}

java 导入EXCEL表格 单元格合并的情况怎么处理,数据放在哪里?

//下面一段代码是来上传文件的 fie是你倒入的文件

InputStream is = new FileInputStream(file); String root = ServletActionContext.getServletContext().getRealPath("WEB-INF/files/"); File newFile = new File(root+"/verify"); //判断文件夹是否存在 if(!newFile.exists()){ newFile.mkdir(); } File destFile = new File(newFile+"/"+this.getFileFileName()); try{ FileOutputStream os = new FileOutputStream(destFile); byte[] buffer = new byte[1024]; int length=0; while((length = is.read(buffer)) 0 ){ os.write(buffer,0,length); } is.close(); os.close(); }catch(Exception e){ e.printStackTrace(); }

文件可以存放在临时文件里面，然后，创建完临时文件后，进行check ，然后插入数据库，上面的是一小段代码，由于保密，就不给你全部发了。

java如何如何实现两张excel表的合并?

你这个是将第二excel的数据追加到第一个excel里吧。

1、你在构建第一个excel的时候，把第二excel数据读出来与源数据同时写入。

2、你可以将两个excel的数据都读出来 放到对象列表中。再将list里的对象写到excel中。
