我有这样一栏:如何从单个列中获取多个列?
Genre
Action|Crime|Drama|Thriller
Action|Crime|Thriller
Drama|Thriller
Crime|Drama
Horror|Thriller
Crime|Drama|Mystery|Thriller
Documentary
Comedy|Crime
Action|Adventure|Sci-Fi
.....
so on.
我想是什么样的多列输出:
it generate various column of genre eg:
action scifi crime adventure . . . . .
0 1 0 1 0
1 0 0 0 0
