Proposition: Top border/padding reprinting on row break

proposition of an alternative way to handle top border/padding printing on row breaks. Actually when a row content break on a new page, the top padding is printed alone on the previous page but not on the new page; idem for the top border; this pull reprint row's top border/padding on each page break and suppress orphan top padding on page bottom
