Hide duplicates in tables only

Hi, 

I have a dataset select distinct values like this 

1 john     USA    MA
1 john     USA    AZ
1 john     USA    TX
2 Bob      USA   CA
2 Bob      USA   NY
3 Mike     USA   MN

I populate a table with 3 columns only from this dataset

so the result is

1 john     USA   
1 john     USA   
1 john     USA   
2 Bob      USA  
2 Bob      USA  
3 Mike     USA  

How can I show in this table distinct result like this

1 john     USA   
2 Bob      USA  
3 Mike     USA 

?

Thanks
