Excel 2007：按列值中的重复项删除行

Question

I have a table in excel. Eg

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: eg:

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.
