HSSFWorkbook wb = new HSSFWorkbook(); HSSFSheet sheet = wb.createSheet("new sheet"); // Create a row and put some cells in it. Rows are 0 based. HSSFRow row = sheet.createRow((short) 1); // Aqua background HSSFCellStyle style = wb.createCellStyle(); style.setFillBackgroundColor(HSSFCellStyle.AQUA); style.setFillPattern(HSSFCellStyle.BIG_SPOTS); HSSFCell cell = row.createCell((short) 1); cell.setCellValue("X"); cell.setCellStyle(style); // Orange "foreground", foreground being the fill foreground not the font color. style = wb.createCellStyle(); style.setFillForegroundColor(HSSFCellStyle.ORANGE); style.setFillPattern(HSSFCellStyle.SOLID_FOREGROUND); cell = row.createCell((short) 2); cell.setCellValue("X"); cell.setCellStyle(style); // Write the output to a file FileOutputStream fileOut = new FileOutputStream("workbook.xls"); wb.write(fileOut); fileOut.close();
请问有没有知道如何控制cell格式的,譬如,设置cell的颜色什么的
HSSFSheet sheet = wb.createSheet("new sheet"); // Create a row and put some cells in it. Rows are 0 based.
HSSFRow row = sheet.createRow((short) 1); // Aqua background
HSSFCellStyle style = wb.createCellStyle();
style.setFillBackgroundColor(HSSFCellStyle.AQUA);
style.setFillPattern(HSSFCellStyle.BIG_SPOTS);
HSSFCell cell = row.createCell((short) 1);
cell.setCellValue("X");
cell.setCellStyle(style); // Orange "foreground", foreground being the fill foreground not the font color.
style = wb.createCellStyle();
style.setFillForegroundColor(HSSFCellStyle.ORANGE);
style.setFillPattern(HSSFCellStyle.SOLID_FOREGROUND);
cell = row.createCell((short) 2);
cell.setCellValue("X");
cell.setCellStyle(style); // Write the output to a file
FileOutputStream fileOut = new FileOutputStream("workbook.xls");
wb.write(fileOut);
fileOut.close();
再请教一个问题,我在导出时,当行数很多时,出现:不能打开文件的记录,但是记录条数较少时却很正常,这是怎么回事,不知您遇见过没有,请赐教,先谢了:)
可以具体点给个地址好吗
四、导出数据到Excel文件中
下面的例子,设置了数字、日期的格式,还有字体,颜色等。File tempFile=new File("d:/temp/output.xls");
WritableWorkbook workbook = Workbook.createWorkbook(tempFile);
WritableSheet sheet = workbook.createSheet("TestCreateExcel", 0); //一些临时变量,用于写到excel中
Label l=null;
jxl.write.Number n=null;
jxl.write.DateTime d=null;//预定义的一些字体和格式,同一个Excel中最好不要有太多格式
WritableFont headerFont = new WritableFont(WritableFont.ARIAL, 12, WritableFont.BOLD, false, UnderlineStyle.NO_UNDERLINE, jxl.format.Colour.BLUE);
WritableCellFormat headerFormat = new WritableCellFormat (headerFont); WritableFont titleFont = new WritableFont(WritableFont.ARIAL, 10, WritableFont.NO_BOLD, false, UnderlineStyle.NO_UNDERLINE, jxl.format.Colour.RED);
WritableCellFormat titleFormat = new WritableCellFormat (titleFont); WritableFont detFont = new WritableFont(WritableFont.ARIAL, 10, WritableFont.NO_BOLD, false, UnderlineStyle.NO_UNDERLINE, jxl.format.Colour.BLACK);
WritableCellFormat detFormat = new WritableCellFormat (detFont); NumberFormat nf=new NumberFormat("0.00000"); //用于Number的格式
WritableCellFormat priceFormat = new WritableCellFormat (detFont, nf); DateFormat df=new DateFormat("yyyy-MM-dd");//用于日期的
WritableCellFormat dateFormat = new WritableCellFormat (detFont, df); //剩下的事情,就是用上面的内容和格式创建一些单元格,再加到sheet中
l=new Label(0, 0, "用于测试的Excel文件", headerFormat);
sheet.addCell(l);//add Title
int column=0;
l=new Label(column++, 2, "标题", titleFormat);
sheet.addCell(l);
l=new Label(column++, 2, "日期", titleFormat);
sheet.addCell(l);
l=new Label(column++, 2, "货币", titleFormat);
sheet.addCell(l);
l=new Label(column++, 2, "价格", titleFormat);
sheet.addCell(l);//add detail
int i=0;
column=0;
l=new Label(column++, i+3, "标题 "+i, detFormat);
sheet.addCell(l);
d=new DateTime(column++, i+3, new java.util.Date(), dateFormat);
sheet.addCell(d);
l=new Label(column++, i+3, "CNY", detFormat);
sheet.addCell(l);
n=new jxl.write.Number(column++, i+3, 5.678, priceFormat);
sheet.addCell(n);i++;
column=0;
l=new Label(column++, i+3, "标题 "+i, detFormat);
sheet.addCell(l);
d=new DateTime(column++, i+3, new java.util.Date(), dateFormat);
sheet.addCell(d);
l=new Label(column++, i+3, "SGD", detFormat);
sheet.addCell(l);
n=new jxl.write.Number(column++, i+3, 98832, priceFormat);
sheet.addCell(n);//设置列的宽度
column=0;
sheet.setColumnView(column++, 20);
sheet.setColumnView(column++, 20);
sheet.setColumnView(column++, 10);
sheet.setColumnView(column++, 20);workbook.write();
workbook.close();
