Is CKeditor able to display a form element ?

I have the same problem... This is the HTML is have inside CKEDITOR 3.0.2

<h2>Contact</h2>
<form action="" method="post">
   <table width="100%">
   <tbody>
      <tr>
      <td width="40%">* Name:</td>
      <td><input maxlength="35" name="data[name]" type="text" value="" /></td>
      </tr>
      <tr>
      <td width="40%">* Email:</td>
      <td><input maxlength="75" name="data[email]" type="text" value="" /></td>
      </tr>
      <tr>
      <td width="40%">* Question:</td>
      <td><textarea cols="30" name="data[question]" rows="10"></textarea></td>
      </tr>
<tr>
<td colspan="2"><input type="submit" name="contact_send" class="submit" value="Send" /></td>
</tr>
   </tbody>
   </table>
</form>

CKEDITOR leaves the following HTML (the submit button is displayed outside of CKEDITOR):

<h2>Contact</h2>
<form action="" method="post">
   <table width="100%">
   <tbody>
      <tr>
      <td width="40%">* Name:</td>
      <td><input maxlength="35" name="data[name]" type="text" value="" /></td>
      </tr>
      <tr>
      <td width="40%">* Email:</td>
      <td><input maxlength="75" name="data[email]" type="text" value="" /></td>
      </tr>
      <tr>
      <td width="40%">* Question:</td>
      <td><textarea cols="30" name="data[question]" rows="10"></textarea></td>
      </tr>
   </tbody>
   </table>
</form>

I tested this and this behavior is in IE8, Firefox 3.5, Chrome 4
Can anybody help?

Ok the solutions is, in PHP, to use htmlspecialchars() function....
