Hi It seems to me like homework, there is no homework policy on this help list. What do you want to do with your table 3? It seems to me futile. Anyway, some combination of melt, merge, cast and regular expressions could be employed in such task, but it could be rather tricky. But be aware that Suger does not match sugar (I wonder that sugar is dairy product) and you mix uppercase and lowercase letters which could be also problematic, when matching words.
