BBCode not working

Well i tried to have a big post with tables and boarders and the like in HTML and made sure to click ALLOW HTML and unclicked disable HTML but alas it just came up a big mess.

Thing is i did the same thing in BBCode and the most basic BBCode won't work such as [borders] etc.

I want an information post with pictures in a table and a boarder around the entire text/images but want it to be simple.

Also resizing an image doesnt work.
