使用：method1(table);  

说明：参数table为table元素的ID;

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 method1(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 xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns="http://www.w3.org/TR/REC-html40"><head><!--[if gte mso 9]><xml><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet><x:Name>{worksheet}</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></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))
    }
})();
