Change FCKeditor for specific spaces

Hello Everyone

I'm looking for an editor, where im able to change the size of the editor, for fx. 200x500px.
If i want the page edited in FCKeditor to fit in a <td> width the size 200x500, and i want to see what i actually get when saving.

I've tried alot of editors, but most of them isn't able to transform to a size as little as 200px in width.

Is that able with this editor?
