怎样将一个页面的内容导出为Excel ??不是用sql，是直接将整个页面打印成Excel .........

怎样将一个页面的内容导出为Excel ??不是用sql，是直接将整个页面打印成Excel .........
这个页面是一个比较复杂的报表，
如果通过sql查询导出，在Excel中的显示将会非常麻烦，实现起来很困难。
所以，俺想省点事，
将整个页面都导为Excel,就像打印一样。
能否实现呢？
Help.!

只见间把页面保存成.xls文件即可。javascript:
//text = aaa.document.body
function savePageASxls(text,title)
{
if(document.queryCommandEnabled('saveAS'))  {
         var para = 'toolbar=0,titlebar=0,menubar=0,resizable=0,Height=7,Width=8,status=0,top=2000,left=2000,scrollbars=0';
         win=open('about:blank','',para);
         win.charset='GB2312';
         win.document.write(text);
         win.document.execCommand('SaveAs',true,title + '.xls');
         win.close();
  }     }
