jquery table.append(table) 不显示

[煎饼皮皮侠]

var table = $("<table>",{"width":"200","height":"200","border":"1"});
var tabhead = $("<table>",{"width":"100","height":"100","border":"1"});
var thead = $("<thead>");
var headtr = $("<tr>");
var headtd = $("<td>");
headtd.text("11");
var headtd2 = $("<td>");
headtd2.text("22");
headtr.append(headtd);
headtr.append(headtd2);
thead.append(headtr);
tabhead.append(thead);
table.append(tabhead);
$("#tab1").append(table);

juqery 在table里嵌套table不显示，如果把外层table换成div，便可以，这是咋回事？

已解决，var table = $("<table>",{"width":"200","height":"200","border":"1"});
var tr = $("<tr>");
var td = $("<td>");
var tabhead = $("<table>",{"width":"100","height":"100","border":"1"});
var thead = $("<thead>");
var headtr = $("<tr>");
var headtd = $("<td>");
headtd.text("11");
var headtd2 = $("<td>");
headtd2.text("22");
headtr.append(headtd);
headtr.append(headtd2);
thead.append(headtr);
tabhead.append(thead);

td.append(tabhead);
tr.append(td);
table.append(tr);
$("#tab1").append(table);
这样便可以
