   sheet.addCell(new Label(0, 0, "号碼"));

   jxl.write.WritableCellFormat wcfDF = new jxl.write.WritableCellFormat(df);
   jxl.write.DateTime labelDTF = new jxl.write.DateTime(1, 1, new Date(), wcfDF); //自定義格式
   sheet.addCell(labelDTF);

   //2.字型樣式
//   WritableFont()方法裡參數說明：
//   這個方法算是一個容器，可以放進去好多屬性
//   第一個: TIMES是字型大小，他寫的是18
//   第二個: BOLD是判斷是否為斜體,選擇true時為斜體
//   第三個: ARIAL
//   第四個: UnderlineStyle.NO_UNDERLINE 下劃線
//   第五個: jxl.format.Colour.RED 字型顔色是紅色的
   jxl.write.WritableFont wf = new jxl.write.WritableFont(WritableFont.TIMES, 18, WritableFont.BOLD, true);
   jxl.write.WritableCellFormat wcfF = new jxl.write.WritableCellFormat(wf);
   wcfF.setWrap(true);//自動換行
   wcfF.setAlignment(jxl.format.Alignment.CENTRE);//把水準對齊方式指定為居中
   wcfF.setVerticalAlignment(jxl.format.VerticalAlignment.CENTRE);//把垂直對齊方式指定為居中
   jxl.write.Label labelC = new jxl.write.Label(0, 1, "This is a Label cell", wcfF);
   sheet.addCell(labelC);

   //3.添加帶有formatting的Number對象
   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(0, 2, 3.1415926, wcfN);
   sheet.addCell(labelNF);

   //4.添加Boolean對象
   jxl.write.Boolean labelB = new jxl.write.Boolean(0, 3, false);
   sheet.addCell(labelB);

   //5.設定一個注解
   WritableCellFeatures cellFeatures = new WritableCellFeatures();
   cellFeatures.setComment("添加Boolean對象");
   labelB.setCellFeatures(cellFeatures);

   //6.單元格内換行
   WritableCellFormat wrappedText = new WritableCellFormat
   (WritableWorkbook.ARIAL_10_PT);
   wrappedText.setWrap(true);//可換行的label樣式
   Label label = new Label(4, 0, "測試,\012測試。。。",wrappedText); // "\012"強制換行
   sheet.addCell(label);

   //7.數字的公式計算
   Number n = new jxl.write.Number(0,9,4.5);//A10
   sheet.addCell(n);
   n = new Number(1,9, 8);//B10
   sheet.addCell(n);
   NumberFormat dp3 = new NumberFormat("#.###"); //設定單元格裡面的數字格式
   WritableCellFormat dp3cell = new WritableCellFormat(dp3);
   dp3cell.setWrap(true);
   Formula f = new Formula(2, 9, "(a10+b10)/2", dp3cell); //設定C10公式
   sheet.addCell(f);
   f = new Formula(3, 9, "SUM(A10:B10)", dp3cell);//設定D10公式
   sheet.addCell(f);

   //8.設定sheet的樣式
   sheet.getSettings().setProtected(true); //設定xls的保護，單元格為隻讀的
   sheet.getSettings().setPassword("123"); //設定xls的密碼
   sheet.getSettings().setDefaultColumnWidth(10); //設定列的預設寬度,2cm左右
   sheet.setRowView(3,200);//設定第4行高度
   sheet.setRowView(2,false);// 這樣可以自動把行高擴充
   sheet.setColumnView(0 , 300);//設定第1列寬度，6cm左右
   sheet.mergeCells(0 , 5, 1, 7);//合并單元格：合并A6B8也就是1列6行 與 2列7行 之間的矩形

   //9.設定邊框
   drawRect(sheet, 5, 6, 7, 6,BorderLineStyle.THICK, Colour.BLACK, null);

   wwb.write();
   wwb.close();
   os.close();
}



public static void drawRect(WritableSheet sheet, int x, int y, int width, int height,BorderLineStyle style,Colour BorderColor, Colour bgColor) throws WriteException {
   for(int w = 0; w < width; w++){

     WritableCellFormat alignStyle = new WritableCellFormat(); //單元格樣式
     alignStyle.setAlignment(Alignment.CENTRE);   //設定對齊方式
     alignStyle.setVerticalAlignment(VerticalAlignment.CENTRE);//設定對齊方式
     if(h == 0)//畫上
      alignStyle.setBorder(Border.TOP, style, BorderColor);//設定邊框的顔色和樣式

     if(w == 0)//畫左
      alignStyle.setBorder(Border.LEFT, style, BorderColor);//設定邊框的顔色和樣式

     Label mergelabel = new Label(x, y, "", alignStyle);
