jxl.write.WritableCellFormat wcfN = new jxl.write.WritableCellFormat(nf);
jxl.write.Number labelNF = new jxl.write.Number(1,1,3.1415926,wcfN);
sheet.addCell(labelNF);

//3.添加Boolean对象
jxl.write.Boolean labelB = new jxl.write.Boolean(0,2,false);
sheet.addCell(labelB);

//4.添加DateTime对象
jxl.write.DateTime labelDT = new jxl.write.DateTime(0,3,new java.util.Date());
sheet.addCell(labelDT);

//添加带有formatting的DateFormat对象
jxl.write.DateFormat df = new jxl.write.DateFormat("ddMMyyyyhh: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);
sheet.addCell(labelDTF);

//和宾单元格
//sheet.mergeCells(int col1,int row1,int col2,int row2);//左上角到右下角
sheet.mergeCells(4,5,8,10);//左上角到右下角
wfc = new jxl.write.WritableFont(WritableFont.ARIAL,40,WritableFont.BOLD,false,jxl.format.UnderlineStyle.NO_UNDERLINE,jxl.format.Colour.GREEN);
jxl.write.WritableCellFormat wchB = new jxl.write.WritableCellFormat(wfc);
wchB.setAlignment(jxl.format.Alignment.CENTRE);
labelCFC = new jxl.write.Label(4,5,"单元合并",wchB);
sheet.addCell(labelCFC); //


//设置边框
jxl.write.WritableCellFormat wcsB = new jxl.write.WritableCellFormat();
wcsB.setBorder(jxl.format.Border.ALL,jxl.format.BorderLineStyle.THICK);
labelCFC = new jxl.write.Label(0,6,"边框设置",wcsB);
sheet.addCell(labelCFC);
workbook.write();
workbook.close();
}catch(Exception e)
{
e.printStackTrace();
}
System.out.println("end");
Runtime r=Runtime.getRuntime();
Process p=null;
//String cmd[]={"notepad","exec.java"};
String cmd[]={"C:\\Program Files\\Microsoft Office\\Office\\EXCEL.EXE","out.xls"};
try{
p=r.exec(cmd);
}
catch(Exception e){
System.out.println("error executing: "+cmd[0]);
}


}



------解决方案--------------------
探讨
调用后台action生成文件,然后输出流。

------解决方案--------------------
一个你可以在点击连接的时候,将页面上的信息都传回去,生成xls,还有一个是条件不变的话,将这些条件传回去,重新查数据库,得到数据,生成xls
