Ok I have been playing around and think I have worked it out, so if anyone else would like to know how to do it you remove <th><?=$this->__('SKU')?></th> form the group.PHTML file (it’s in there twice).
But the main problem I was having is still there the £ sign and the price are appearing on different lines(pic attached). Anyone know how to solve this?
Or if it’s a bug I would like to report it.
