Unterminated string constant error

For some reason when I pass the following text to FCKEditor, it bombs out with an Unterminated string constant javascript error. I am passing it from a MySQL query through a php variable after I pass it through the addslashes() function. If I use a simple string like asdasd it works fine. It even works if I add single or double quotes to the string, but something in this text causes it to not load:

<table>
<tbody>
<tr>
<td>A</td>
<td>A</td>
</tr>
<tr>
<td>A</td>
<td>A</td>
</tr>
<tr>
<td>A</td>
<td>A</td>
</tr>
</tbody>
</table>

Thanks for any help
