There are major limitations to using JS methods to invoke page tables to export excel:
1. I have tried several browsers, but only IE supports it.
2, click tools -- security -- custom level --ActiveX related options enabled
Here's the HTML code

 
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> 
<% 
String path = request.getContextPath(); 
String basePath = request.getScheme() + "://" 
+ request.getServerName() + ":" + request.getServerPort() 
+ path + "/"; 
%> 
<html> 
<head> 
<script language="javascript"> 
var idTmr = ""; 
//Function function: copy table to Excel
//Parameter: id of tableID table
function CellToTable(tableID) 
{ 
var tid=document.getElementById(tableID); 
//Load the ActiveX control and get the Excel handle
var exApp = new ActiveXObject("Excel.Application"); 

//Create an Excel file
var owb = exApp.WorkBooks.add(); 

//Gets the sheet1 handle CA
var exSheet = exApp.ActiveWorkBook.WorkSheets(1); 
//Set the name of sheet1
exSheet.name=" Demo copy table to Excel In the "; 
//Copy the specified form
var sel=document.body.createTextRange(); 
sel.moveToElementText(tid); 
sel.select(); 
sel.execCommand("Copy"); 

exSheet.Paste();//Paste it into the sheet

//exApp.save();//  Save dialog box, save Excel file  
exApp.Visible = false; 

var fname = exApp.Application.GetSaveAsFilename("save.xls", "Excel Spreadsheets (*.xls), *.xls"); 
owb.SaveAs(fname); 

exApp.Quit();//Exit the Excel instance
exApp = null; 
//Call Cleanup () for garbage collection
idTmr = window.setInterval("Cleanup();",10); 

} 
//Kill Excel process
function Cleanup() { 
window.clearInterval(idTmr); 
CollectGarbage(); 
} 
</script>
