E1 thru E10 contains sequentially-sorted data. B1 thru B6 contains
sequentially-sorted data which matches SOME (but not ALL) of the data
in Col A. For example.

B E
1 1 1
2 3 2
3 4 3
4 5 4
5 6 5
6 10 6
7 7
8 8
9 9
10 10

I need to move the data in the cells in Col B next to the cells in Col
E that have the same contents. For example:

B E
1 1 1
2 2
3 3 3
4 4 4
5 5 5
6 6 6
7 7
8 8
9 9
10 10 10

Besides dragging and dropping, is there a better way to do this?

(In my actual spreadsheet, Col B contains 718 cells and Col E contains
65,530 cells).
