[SOLVED] How can I insert a preformatted table avoiding Atahualpa to override its sty

Hi,
currently Atahualpa applies some nice styles to tables.

The problem is that I need to post an already styled table that I got from a spreadsheet. That table is full of colors, and those colors have a deep meaning, so I would be able to show the table as it is.

Sadly, Atahualpa has css style that are applied to each table contained in posts. This is great generally speaking, because it ensures a consistent style across the blog, but it's not what I need in this very peculiar scenario.

So... Does anyone knows if there is a way to make sure a table get show with its original colors ?

Removing or modifying the Atahualpa css is not a solution, 'cause it would modify the appearance of all tables across the blog.

Thank you very much

Daniele
