Excel 2007: Remove rows by duplicates in column value

Question

I have a table in excel. E.g.

col1    col2
A       Something    
A       Something else   
A       Something more   
A       Something blahblah   
B       Something Fifth   
B       Something xth
C       Som thin
F       Summerthing
F       Boom

And I want only rows without duplicate col1: e.g:

col1    col2
A       Something    
B       Something Fifth   
C       Som thin
F       Boom

Is there any way of filtering rows like this :) ?

Found it myself:

To remove duplicate values, use the Remove Duplicates command in the Data Tools group on the Data tab.
