如何将包含多个值的列(每行​)分成多个列

Question

大家早上好。

我有一个很大的数据帧，特别是我有一个包含5到15个元素的列(一个列表)。我想把它分成多列，每列的元素有多少。

    A                  B                 JHON
   GREEN    c("abc", "def", "ghi")       yellow
   RED      c("123", "456", "789")       blue
   JACK     d("rgy", "bob", "pbc")       pink

我想要实现这样的事情

    A          B       C       D    JHON
  GREEN       abc      def    ghi   yellow
  RED         123      456    789   blue
  JACK        rgy      bob    pbc   pink


ah <- c("A", "B", "C")

separate(df , unlist(df$B), ah )

我试图设置一个这样的东西，但是我得到了下面的错误

Errore: Must extract column with a single valid subscript.
x Subscript `var` has size 5322 but must be size 1.

提前感谢所有能帮助我的人。我添加了我感兴趣的列

 ProductGallery = list(
    c("http://images.icecat.biz/img/gallery/15656565_3828389912.jpg", 
    "http://images.icecat.biz/img/gallery/15656565_0985217712.jpg",

尝试以下操作：

df$C <- df$B[2]
df$D <- df$B[3]
df$B <- df$B[1]
