利用Java控制EXCEL实例详解

try 
{ 
//构建Workbook对象, 只读Workbook对象 
//Method 1：创建可写入的Excel工作薄 
jxl.write.WritableWorkbook wwb = Workbook.createWorkbook(new File(targetfile)); 
//Method 2：将WritableWorkbook直接写入到输出流 
/* 
OutputStream os = new FileOutputStream(targetfile); 
jxl.write.WritableWorkbook wwb = Workbook.createWorkbook(os);

catch (Exception e)

file://创建Excel工作表 
jxl.write.WritableSheet ws = wwb.createSheet("Test Sheet 1", 0);

file://1/.添加Label对象 
jxl.write.Label labelC = new jxl.write.Label(0, 0, "This is a Label cell"); 
ws.addCell(labelC); 
//添加带有字型Formatting的对象 
jxl.write.WritableFont wf = new jxl.write.WritableFont(WritableFont.TIMES, 18, 
WritableFont.BOLD, true); 
jxl.write.WritableCellFormat wcfF = new jxl.write.WritableCellFormat(wf); 
jxl.write.Label labelCF = new jxl.write.Label(1, 0, "This is a Label Cell", wcfF); 
ws.addCell(labelCF); 
//添加带有字体颜色Formatting的对象 
jxl.write.WritableFont wfc = new jxl.write.WritableFont(WritableFont.ARIAL, 10, 
WritableFont.NO_BOLD, false, 
UnderlineStyle.NO_UNDERLINE, jxl.format.Colour.RED); 
jxl.write.WritableCellFormat wcfFC = new jxl.write.WritableCellFormat(wfc); 
jxl.write.Label labelCFC = new jxl.write.Label(1, 0, "This is a Label Cell", wcfFC); 
ws.addCell(labelCF); 
//2.添加Number对象 
jxl.write.Number labelN = new jxl.write.Number(0, 1, 3.1415926); 
ws.addCell(labelN); 
//添加带有formatting的Number对象 
jxl.write.NumberFormat nf = new jxl.write.NumberFormat("#.##"); 
jxl.write.WritableCellFormat wcfN = new jxl.write.WritableCellFormat(nf); 
jxl.write.Number labelNF = new jxl.write.Number(1, 1, 3.1415926, wcfN); 
ws.addCell(labelNF); 
//3.添加Boolean对象 
jxl.write.Boolean labelB = new jxl.write.Boolean(0, 2, false); 
ws.addCell(labelB); 
//4.添加DateTime对象 
jxl.write.DateTime labelDT = new jxl.write.DateTime(0, 3, new java.util.Date()); 
ws.addCell(labelDT); 
//添加带有formatting的DateFormat对象 
jxl.write.DateFormat df = new jxl.write.DateFormat("dd MM yyyy hh:mm:ss"); 
jxl.write.WritableCellFormat wcfDF = new jxl.write.WritableCellFormat(df); 
jxl.write.DateTime labelDTF = new jxl.write.DateTime(1, 3, new java.util.Date(), wcfDF); 
ws.addCell(labelDTF);
