如何实现将统计表格保存成Excel文件

java,jsp,javascript中如何实现将统计表格保存成excel文件？
---------------------------------------------------------------

function AutomateExcel()
{
var i,j;
// Start Excel and get Application object.
var oXL = new ActiveXObject("Excel.Application");

oXL.Visible = true;

// Get a new workbook.
var oWB = oXL.Workbooks.Add();
var oSheet = oWB.ActiveSheet;

// Add table headers going cell by cell.
// tblout表的ID
for(i=0;i< tblout.rows.length;i++)
for(j=0;j< tblout.rows(i).cells.length;j++)
oSheet.Cells(i+1, j+1).Value = tblout.rows(i).cells(j).innerText

oXL.Visible = true;
oXL.UserControl = true;
}
//这个问题其实你搜一下就有了

首先你的页面上要有一个按钮：save
这个按钮先做查询数据库，然后action转到保存excell的页面，即我给你的这些代码，由于我的是用这个页面是隐藏的，点击save时有跳出界面问你是打开还是保存，xxxxxxxxxxxxxx是你调用数据库的记录，

try{
response.setContentType("Application/m易做图cel");
response.setHeader("Content-Disposition", "attachment;filename=trainlist.xls");
StringBuffer cont=new StringBuffer("");
