I have no idea... I guess I need to clean up the article again. The table, It was mine idea, and work. Secondly, just find me the info, and I will change it like the updated Purchase age, and smoking age. Also, I find no set definition for region. Instead of dividing the website, we better use these /info/en/?search=Template:Regions_of_the_world. So We could include the sub region too, if we wanted to. If we did, it would look something like this

Region of the world Sub-Region	Country	Region of the country	Smoking age(s) De jure	Purchase age(s) De jure	Note
North America Caribbean sea	Cuba	All	None	16	The Ministry of Commerce Resolution bans the sale of cigarettes to persons under the age of 16. [1]
Europe Central	Switzerland	Bern,   Basel-Landschaft,   Basel-Stadt,   Schaffhausen,   Jura,   Neuchâtel,   Nidwalden,   Schaffhausen,   Ticino,   Vaud and   Zug.	18 [2]
		Aargau,   Appenzell Ausserrhoden,   Fribourg,   Glarus,   Graubünden,   Lucerne,   St. Gallen,   Solothurn,   Thurgau,   Uri,   Valais and   Zürich.	16 [2]
		Appenzell Innerrhoden,   Geneva,   Obwalden and   Schwyz	None [2]

For example. And that is, if you want to help.
