How to add spaces in selected records in SQLite?

I am making a windows forms application. In a report, I need the following output.

Name                Total_Weight   ....
Employee1              1000        ....
  -Gold                 500        ....    
  -Silver               500        ....
Employee2              2500        ....
  -Gold                1000        ....
  -Silver              1500        ....

So far I have achieved as below...

Employee1
Gold
Silver   

So the question is how to add space in selected records? As you cans see in second result, I want to add two spaces and - in beginning of the word. I am using SQLite database and front end is C#.
