在Java中向Excel文件寫入內(nèi)容
四、導(dǎo)出數(shù)據(jù)到Excel文件中
下面的例子，設(shè)置了數(shù)字、日期的格式，還有字體，顏色等。
File tempFile=new File("d:/temp/output.xls");
WritableWorkbook workbook = Workbook.createWorkbook(tempFile);
WritableSheet sheet = workbook.createSheet("TestCreateExcel", 0);
//一些臨時(shí)變量，用于寫到excel中
Label l=null;
jxl.write.Number n=null;
jxl.write.DateTime d=null;
//預(yù)定義的一些字體和格式，同一個(gè)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，就是用上面的內(nèi)容和格式創(chuàng)建一些單元格，再加到sheet中
l=new Label(0, 0, "用于測(cè)試的Excel文件", headerFormat);
sheet.addCell(l);
//add Title
int column=0;
l=new Label(column++, 2, "標(biāo)題", titleFormat);
sheet.addCell(l);
l=new Label(column++, 2, "日期", titleFormat);
sheet.addCell(l);
l=new Label(column++, 2, "貨幣", titleFormat);
sheet.addCell(l);
l=new Label(column++, 2, "價(jià)格", titleFormat);
sheet.addCell(l);
//add detail
int i=0;
column=0;
l=new Label(column++, i+3, "標(biāo)題 "+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, "標(biāo)題 "+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);
//設(shè)置列的寬度
column=0;
sheet.setColumnView(column++, 20);
sheet.setColumnView(column++, 20);
sheet.setColumnView(column++, 10);
sheet.setColumnView(column++, 20);
workbook.write();
workbook.close();
