I have two dataframes where 1, 2, 3 is the connection between the dataframes:
              1    2    3 
2016-10-03   12   10   10 
2016-10-04   4     4    5 
......
and
     name    year
1   apple    2001
2   lemon    2002
3   kiwi     1990
The end result should be:
              apple    lemon    kiwi 
2016-10-03       12       10      10 
2016-10-04        4        4       5 
......
I can't figure out how to do this.
