Need to match and sort data in 6 columns

[gbunt8199]

PLEASE HELP! I'm trying to put together a fairly important financial report, and I'm pretty ignorant when it comes to doing more than the most basic functions with Excel.

Here's what I'm working on:

Column A has donor name, column B has corresponding donation data for 2011. Column C has donor name, and column D has donation data for 2012. Column E has donor name, and column F has corresponding donation data for 2013.

Although Columns A and C and E all have donor names, there are many changes
from year to year with the addition and deletion of certain donors so the
rows do not match up exactly. Is there a quick way to have the rows match up
according to donor names in column each of the three columns? Secondarily, I need to sort by donation amount from highest to lowest (it can either be the total over the three years or based on any single year.

Currently my list looks like this:
2011 2012 2013
A A A
B C B
D D C
F E D
H F I
L G K
M H M

I would like it to look like this:
2011 2012 2013
A A A
B - B
C C -
- D-
- E-
F F F
G G G
H - -
L - L
- - M


Basically, I want to see the year over year giving for each donor. I've attached a sample for refrence. (I can't post the original due to confidentiality requirements.)
