Hi - I have a visualforce page.. within the page, I have a pageblock, pageblocksection, dataTable and then I have 10 columns (I know that is a lot)  The problem is the data is all crowded together.

It there any way to wrap the data so that perhaps it takes up two rows for each record? 

Any suggestions would be greatly appreciated!!

thanks!!
Fred
