寫個測試

public static void main(String[] args) throws Exception {
  test();
}


@SuppressWarnings({ })
public static void test() throws Exception{
     excel();
     //設定單元格的樣式
     WritableFont contentFont = new WritableFont(WritableFont.createFont("微軟雅黑"), 10, WritableFont.BOLD,false,UnderlineStyle.NO_UNDERLINE);

     WritableCellFormat contentFormat2 = new WritableCellFormat(contentFont);
     //設定邊框
     contentFormat2.setBorder(jxl.format.Border.ALL, jxl.format.BorderLineStyle.THIN
                                ,jxl.format.Colour.BLACK);
     //設定自動換行
     contentFormat2.setWrap(true);
     //設定水平居中
     contentFormat2.setAlignment(jxl.format.Alignment.CENTRE);

     sheet.addCell(new Label(2,3,"本月新增",contentFormat2));
     Close();
}


public static void Close() throws IOException, WriteException{
    //開始執行寫入操作
    book.write();
    //關閉流
    book.close();
}

效果如圖:
