             var oWB = oXL.Workbooks.Add();  
             var xlsheet = oWB.Worksheets(1);  
             var sel = document.body.createTextRange();

调用这个 :exportExcel(tableid);

var idTmr;    function getExplorer() {    var explorer = window.navigator.userAgent ;    //ie    if (explorer.indexOf("MSIE") >= 0) {    return 'ie';    }    //firefox    else if (explorer.indexOf("Firefox") >= 0) {    return 'Firefox';    }    //Chrome    else if(explorer.indexOf("Chrome") >= 0){    return 'Chrome';    }    //Opera    else if(explorer.indexOf("Opera") >= 0){    return 'Opera';    }    //Safari    else if(explorer.indexOf("Safari") >= 0){    return 'Safari';    }    }    function exportExcel(tableid) {    if(getExplorer()=='ie')    {    var curTbl = document.getElementById(tableid);    var oXL = new ActiveXObject("Excel.Application");    var oWB = oXL.Workbooks.Add();    var xlsheet = oWB.Worksheets(1);    var sel = document.body.createTextRange();    sel.moveToElementText(curTbl);    sel.select();    sel.execCommand("Copy");    xlsheet.Paste();    oXL.Visible = true;
try {    var fname = oXL.Application.GetSaveAsFilename("Excel.xls", "Excel Spreadsheets (*.xls), *.xls");    } catch (e) {    print("Nested catch caught " + e);    } finally {    oWB.SaveAs(fname);    oWB.Close(savechanges = false);    oXL.Quit();    oXL = null;    idTmr = window.setInterval("Cleanup();", 1);    }
}    else    {    tableToExcel(tableid)    }    }    function Cleanup() {    window.clearInterval(idTmr);    CollectGarbage();    }    var tableToExcel = (function() {    var uri = 'data:application/vnd.ms-excel;base64,',    template = '<html><head><meta charset="UTF-8"></head><body><table>{table}</table></body></html>',    base64 = function(s) { return window.btoa(unescape(encodeURIComponent(s))) },    format = function(s, c) {    return s.replace(/{(\w+)}/g,    function(m, p) { return c[p]; }) }    return function(table, name) {    if (!table.nodeType) table = document.getElementById(table)    var ctx = {worksheet: name || 'Worksheet', table: table.innerHTML}    window.location.href = uri + base64(format(template, ctx))    }    })()
