Hi Rashmin, if i understand your problem correctly, select the table tab, i select the table that needs to be copied from the drawing tree, rather than the table itself, RMB select "copy", now heres the thing, you need to unselect the table before the "paste" command will appear next time you RMB. Its like everything in Creo2, where drawings are concerned, its just so mind blowingly difficult to do anything, have you tried translating 2d items? what a nightmare.
