用js做导出table到execl，兼容不是很好，但这个方法可以，我项目中使用了，另外我参考老外的东西，做了局部改进

<script>
 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 method5(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(tabloid,‘name‘,‘my file.xls‘)  
            }  
        }  
        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 border="1">{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,filename) {  
                if (!table.nodeType) table = document.getElementById(table)  
                var ctx = {worksheet: name || ‘Worksheet‘, table: table.innerHTML}  
                document.getElementById("dlink").href = http://www.mamicode.com/uri + base64(format(template, ctx))  
                document.getElementById("dlink").download = filename;
                document.getElementById("dlink").click();
            }  
        })()
</script>

Html中在 导出按钮出加一个a标签<a id="dlink" style="display:none"></a>
