[TYPO3] How can I define a max width for inserted content?

[Christopher]

Hi,

I have inserted a table from Microsoft Word in the RTE-window.
The table it is to broad for my frontend.
For pictures I know that there is a possibility to enter the maxWidth of a 
block; is there something similar for tables?

Or any other possiblity to give them a binding maximum width?
