Is there any way that curved lines can be used when drawing a table in dreamweaver MX??

u cant draw a curved table using mx..

but u can use css and or images to make them round..

I've never actually worked with curves in CSS. I usually just use images as bordering cells with no padding in order to get the desired border on. You can add more complicated effects that way, too.

Yes you have to fill the side and top cells with images and create exactly what you need.
