[TYPO3] Problem styling tables (contenttable)

[Morten Kjems]

Hi.

I am using Tinyrte to create tables for my pages.

I use several different styles for my tables and it is nice that I can 
attach these styles with a few clicks using Tinyrte.

But the problem is TYPO3 somehow overwrites the classes that I have 
defined in my stylesheet and attach a default class named: "contenttable".

Is there a way to avoid this automatic attachment of the style 
"contenttable" so that I can use my own styles?

All suggestions are Welcome.

Thanks
