1、js的方法

A、将整个表格拷贝到EXCEL中

function method1(tableid) {

var curTbl = document.getElementById(tableid);

var oXL = new ActiveXObject("Excel.Application");

var oWB = oXL.Workbooks.Add();

var oSheet = oWB.ActiveSheet;

var sel = document.body.createTextRange();

sel.moveToElementText(curTbl);

sel.select();

sel.execCommand("Copy");

oSheet.Paste();

oXL.Visible = true;

} B、读取表格中每个单元到EXCEL中：

function method2(tableid)

{

var curTbl = document.getElementById(tableid);

var oXL = new ActiveXObject("Excel.Application");

var oWB = oXL.Workbooks.Add();

var oSheet = oWB.ActiveSheet;

var Lenr = curTbl.rows.length;

for (i = 0; i < Lenr; i++)

{ var Lenc = curTbl.rows(i).cells.length;

for (j = 0; j < Lenc; j++)

{

oSheet.Cells(i + 1, j + 1).value = curTbl.rows(i).cells(j).innerText;

}

}

oXL.Visible = true;

} c、把表格输出到另一个页面，然后存成cvs格式

function getXlsFromTbl(inTblId, inWindow){

try {

var allStr = "";

var curStr = "";

if (inTblId != null && inTblId != "" && inTblId != "null") {

curStr = getTblData(inTblId, inWindow);

}

if (curStr != null) {

allStr += curStr;

}

else {

alert("你要导出的表不存在");

return;

}

var fileName = getExcelFileName();

doFileExport(fileName, allStr);

}

catch(e) {

alert("导出发生异常:" + e.name + "->" + e.description + "!");

}

}

function getTblData(inTbl, inWindow) {

var rows = 0;

var tblDocument = document;

if (!!inWindow && inWindow != "") {

if (!document.all(inWindow)) {

return null;

}

else {

tblDocument = eval(inWindow).document;

}

}

var curTbl = tblDocument.getElementById(inTbl);

var outStr = "";

if (curTbl != null) {

for (var j = 0; j < curTbl.rows.length; j++) {

for (var i = 0; i < curTbl.rows[j].cells.length; i++) {

if (i == 0 && rows > 0) {

outStr += " \t";

rows -= 1;

}

outStr += curTbl.rows[j].cells[i].innerText + "\t";

if (curTbl.rows[j].cells[i].colSpan > 1) {

for (var k = 0; k < curTbl.rows[j].cells[i].colSpan - 1; k++) {

outStr += " \t";

}

}

if (i == 0) {

if (rows == 0 && curTbl.rows[j].cells[i].rowSpan > 1) {

rows = curTbl.rows[j].cells[i].rowSpan - 1;

}

}

}

outStr += "\r\n";

}

}

else {

outStr = null;

alert(inTbl + "不存在 !");

}

return outStr;

}

function getExcelFileName() {

var d = new Date();

var curYear = d.getYear();

var curMonth = "" + (d.getMonth() + 1);

var curDate = "" + d.getDate();

var curHour = "" + d.getHours();

var curMinute = "" + d.getMinutes();

var curSecond = "" + d.getSeconds();

if (curMonth.length == 1) {

curMonth = "0" + curMonth;

}

if (curDate.length == 1) {

curDate = "0" + curDate;

}

if (curHour.length == 1) {

curHour = "0" + curHour;

}

if (curMinute.length == 1) {

curMinute = "0" + curMinute;

}

if (curSecond.length == 1) {

curSecond = "0" + curSecond;

}

var fileName = "table" + "_" + curYear + curMonth + curDate + "_"

+ curHour + curMinute + curSecond + ".csv";

return fileName;

}

function doFileExport(inName, inStr) {

var xlsWin = null;

if (!!document.all("glbHideFrm")) {

xlsWin = glbHideFrm;

}

else {

var width = 6;

var height = 4;

var openPara = "left=" + (window.screen.width / 2 - width / 2)

+ ",top=" + (window.screen.height / 2 - height / 2)

+ ",scrollbars=no,width=" + width + ",height=" + height;

xlsWin = window.open("", "_blank", openPara);

}

xlsWin.document.write(inStr);

xlsWin.document.close();

xlsWin.document.execCommand('Saveas', true, inName);

xlsWin.close();

} 总结：比较上面3种方法，感觉第一种方法比较完美一些，因为这种方法比较完整的输出表格的格式。但，第一和第二种方法都用了ActiveX 对象，对客户端的安全有要求，而且最大的问题还有一个，就是excel 对象无法关闭。第3中方法虽然没有用ActiveX 对象，但是用了弹出窗口输出， 如果禁止了弹出窗口则无法使用。

对于execl 对象无法关闭的问题，下面的方法是一个权宜方法：

function Cleanup() {

window.clearInterval(idTmr);

CollectGarbage();

} 调用方法：

idTmr = window.setInterval("Cleanup();",1);2、Asp.net(c#)中的方法这种方法其实类似上面的js的第3中方法(也可以在其他的web脚本来实现，比如asp中vbscript，或者php)，把表格用文件流的方式输出为excel。实例代码如下：public void OutPutExcel(string title)

{

Response.Clear();

Response.Buffer = true;

Response.Charset = "utf-8";

Response.AddHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(title + ".xls"));

Response.ContentEncoding = System.Text.Encoding.GetEncoding("utf-8");

Response.ContentType = "application/ms-excel";

Page.EnableViewState = false;

System.IO.StringWriter oStringWriter = new System.IO.StringWriter();

System.Web.UI.HtmlTextWriter oHtmlTextWriter = new System.Web.UI.HtmlTextWriter(oStringWriter);

this.Page.RenderControl(oHtmlTextWriter);

string temp = oStringWriter.ToString();

Response.Write(temp);

Response.End();

}这种方法的从本质上说并非标准的excel格式，不过把html格式的文件另存为excel的格式，然后用excel打开罢了。3、利用ExceL Application或者MSOWC 或者ado.net这种方法都是利用服务器的组件来时实现，要求服务端要安装excel，具体的代码可以看下面的链接：http://www.cnblogs.com/pucumt/archive/2006/09/13/503120.htmlhttp://support.microsoft.com/default.aspx?scid=kb;zh-cn;306023#top我不提倡用这种方法，因为需要占用服务器的资源。
