Extracting column name from table

I have a dataframe:

df:

ID  Date   A B C  1  201901  4 5 2  1  201902  3 4 2  

I have another table: df1:

 Columns    B    C  

While keeping the ID, and Date column.. and I trying to use the columns given in the table as well.

Currently I am using,

  df1 = list(df1['Columns']    df1 = ''.join(df1)    df = df[['ID','Date',df1]]    print(df)  

This method isn't working for me.

While I can manually insert B and C.. i need a generalized code that can work with any given table.

Expected output:

   ID  Date   B C     1  201901  5 2     1  201902  4 2
