Disable <p> tag in Line break converter

Is there a way to disable the paragraph tag < p > and just use < br > in Line break converter?

When there's some HTML code that goes to the next line or has line breaks, Drupal will insert paragraph tags, and sometimes that causes formating problems.

For example, original code:

<tr>
<td width="150">AAA</td>
<td valign="top">

ABCDEF</td></tr>

<tr><td>

after being submitted becomes:

<tr>
<td width="150">AAA</td>
<td valign="top">
<p>ABCDEF</td>
</tr>
</p>
<p>
<tr>
<td>
