我要在第二列插入表格,可是没有任何反映,也没有提示出错?

<html>
<head>
</head>
<body>
<script   language= "JavaScript ">
function   a(){
MainTable.cells[1].appendChild(SubTable1);
}
</script>
<table   id= "MainTable "   border=2px   width=100%>
<tr>
<td>
<table   id= "SubTable1 "   border=1px   width=100%>
<tr> <td> ST1td1 </td> </tr>
<tr> <td> ST1td2 </td> </tr>
</table>
</td>
<td>
<table   id= "SubTable2 "   border=1px   width=100%>
<tr> <td> ST2td1 </td> </tr>
<tr> <td> ST2td2 </td> </tr>
</table>
</td>
<td>
<table   id= "SubTable3 "   border=1px   width=100%>
<tr> <td> ST3td1 </td> </tr>
<tr> <td> ST3td2 </td> </tr>
</table>
</td>
<tr>
</table>
<input   type= "button "   value= "在第二列插入表格 "   onClick= "a ">
</body>
</html>
