html中append追加的表格元素和静态显示的元素样式不同_html/css

最近在仿写12306火车票查询页面。将12306网站的样式取了下来，其静态页面显示正常，但是通过ajax调用后台数据，再通过append回显却出现了表格挤压的情况。

1、正常显示页面如下：

html代码：

车次	出发站到达站	id="startendtime"> 出发时间到达时间	id="_span_lishi" style="cursor: pointer;">历时	商务座	特等座	一等座	二等座	高级软卧	软卧	硬卧	软座	硬座	无座	其它	备注
onclick="mystopstation.open('1','65000c704001','szq','ggq','20151023','3')" href="javascript:" class="number">c7040 class="lookup" id="65000c704001_01_05_omo" title="查看票价" style="cursor: pointer;"> 深圳广州东 12:48 14:00 1小时12分当日到达	--	--	90	282	--	--	--	--	--	无	--

2、通过ajax向后台发起请求，并通过append回显结果，却出现了表格被收缩的情况。如下图：

js代码如下：
function trainquery(type){
//查询火车余票信息
var tcktyp = type;
var qrydate = $("#train_start_date").val();
var fromstn = $("#fromstationtext").val();
var tostn = $("#tostationtext").val();
var requestparams = "?qrydte=" + qrydate + "&fromstn=" + fromstn + "&tostn=" + tostn + "&tcktyp=" + tcktyp;
var paraobj = { apiid: 102, interfaceid: 3, requestparams: requestparams};
$.ajax({
url : "${skx}/practicaltool",
type : "get",
datatype : "json",
data : paraobj,
success : function(json) {
if(json.resultcode == "200"){
var data = json.data;

var fromstan = "";

$("#_query_table_datas").css({"display" : "block"});
$("#_query_table_datas").html("");
$.each(data, function(i, traindata){
fromstan = traindata.fromstan;
var traincontent = "\n\n";

traincontent += "

\n";
traincontent += "

\n" + traindata.stantraincde + "\n";
traincontent += "

\n\n";
traincontent += "

\n " + traindata.fromstan + " " + traindata.tostan + "\n";
traincontent += "

\n" + traindata.starttme + " " + traindata.arvtme + "\n

\n";
traincontent += "

\n" + traindata.spttme + " " + traindata.daydif + "\n

\n\n";
traincontent += "\n" + traindata.sw_num + "\n\n";
traincontent += "\n" + traindata.td_num + "\n\n";
traincontent += "\n" + traindata.yd_num + "\n\n";
traincontent += "\n" + traindata.ed_num + "\n\n";
traincontent += "\n" + traindata.gr_num + "\n\n";
traincontent += "\n" + traindata.rw_num + "\n\n";
traincontent += "\n" + traindata.yw_num + "\n\n";
traincontent += "\n" + traindata.rz_num + "\n\n";
traincontent += "\n" + traindata.yz_num + "\n\n";
traincontent += "\n" + traindata.wz_num + "\n\n";
traincontent += "\n" + traindata.qt_num + "\n\n";
traincontent += "\n\n";
traincontent += "\n";
$("#_query_table_datas").append($(traincontent));
});

alert("fromstan:" + fromstan);

$(".errmsg").html("");
}
else{
$("#_query_table_datas").css({"display" : "none"});
$(".errmsg").html(json.reason);
}
},
error : function(){
$("#_query_table_datas").css({"display" : "none"});
$(".errmsg").html("火车票查询异常!");
}
});

return;
}

尝试了很多办法都不奏效，无奈之下只好到贵论坛寻求帮助！

审查元素检查下结构和样式

宽度是不是被限制了，查看查看样式？？

审查元素看到的html如下：

td里面的style是因为宽度不生效试图通过这种方式改善，结果无效。

style="white-space: nowrap;width=49px;"

登录后复制

审查结果显示第一个单元格宽度是13，不是49，也设置了不让文字换行。

好消息，已经找到问题答案了。问题出在对tbody设置了display:block属性，让表格不再适应原有宽度。注释掉如下代码就可以了。

$("#_query_table_datas").css({"display" : "block"});
