php - which is better every user have a table or just a row -

i making android app part of user upload videos , inter details , stuff , choose videos favorite , found videos uploaded in 1 place , better making every user table or row in table

create row every user in table. details , other stuff should in rows in other tables , linked via primary key , foreign key.

if create table every user take space , not that, have access different table every user, makes complicated. in rows can access single user primary key of corresponding row.
