If this was the only issue with Creo or Pro/E I would be happy found so many problems with it I have had to knuckle down and bare it, For the formatting tables I have created a map key that fixes it you highlight the row/cell and mapkey sorts out formatting
i deleted my idea since i found this one.. nothing worse than this.. however.. i think when adding a row inside the table.. it follows the format.. but adding a row at the bottom.. does not..
