How to insert a table in HTML Editor?

Hi All:

I am building a WYSIWYG HTML Editor for my web application using Mitchell Harper's article as example. I want to insert a table as I can do it in Microsoft word or FrontPage, is it possible?
If I already know the content and structure of the table, for example, if I have "<table border=0 cellpadding=2 width=500><tr><td>AB</td><td>CD</td>
</tr><tr><td>EF</td><td>GH</td></tr></table>", can I insert it? If yes, will it be dsiplayed as a table?

Any help will be highly appreciated.
