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 disaply incorrectly Is there a plugin avaiable that allows me to make a html table quickly and neatly?

 

Try WP-Table Reloaded.

 

Try the TinyMCE Advance plugin, which allows you to insert tables automatically, plus adds a bunch of cool functions to your editor.
