dataframe相减

根据引用中的示例，DataFrame可以使用`sub()`方法进行相减操作。根据引用中的示例，DataFrame和Series的数据如下:
DataFrame:

   a  b  c
one     0  1  2
two     3  4  5
threee  6  7  8

Series:

one      1
two      4
threee   7
Name: b, dtype: int32

那么，对DataFrame进行相减操作可以如下所示:

frame.sub(series, axis=0)

运行结果如下:

   a  b  c
one    -1  0  1
two    -1  0  1
threee -1  0  1

因此，DataFrame相减的结果为:

   a  b  c
one    -1  0  1
two    -1  0  1
threee -1  0  1
