Hello,

I apologize if this question has already been answered, but I was
unable to find an answer by searching the message archives. Perhaps
this is because I am not exactly sure how to describe the function that
I want to perform.

I have to columns of numbers/data points. Column A contains say 35,000
numbers/data points and Column B contains only 33,000 data points. For
every number/data point in column B there is an identical number/data
points in column A. Basically, 2000 data points have been removed from
coumn B. I want to align (or perhaps sort) the columns such that
identical data points are aligned by row. When there is no
corresponding number in column B for the number in column A a blank
cell will be in column B -- indicating the lack of an identical number.
If this was not clear (which I'm sure it wasn't), below is a much
simpler version of what my data looks like now and what I would like it
to like.

What the data looks like now:

Col A Col B
9 9
8 8
7 6
6 5
5 4
4 2
3 1
2
1

What I would like the data to look like:
Col A Col B
9 9
8 8
7
6 6
5 5
4 4
3
2 2
1 1
