Is the following valid HTML? What I am wondering about specifically is the location of the <form> tag.
<table>
<form>
<tr>
<td>
<input id="txt" type="text"></input>
</td>
<td>
<input id="txt" type="text"></input>
</td>
<td>
<input type="submit"></input>
</td>
</tr>
</form>
</table>
I recomment using the w3c validator http://validator.w3.org/. And no its not valid 🙂
