How to add HTML table in Wordpress? Any plugins?

I want to make a site which uses a lot of tables to display information. In the past Ive used Text edit to create a table, but inserting the code just makes the table look weird. Is there a plugin avaiable that allows me to do this quickly?

 

You can use Windows Live Writer to insert tables and publish to your blog. No coding required.

 

Be careful going overboard with tables. They make your site much harder to crawl and you may affect your ranking.
