`Console.WriteLine("Students {0}", variable)`

This i understand but what does it mean when you put two numbers within the bracket example:

`Console.WriteLine("Students {0,2}: {1,3}", student + 1, grades [student])`

What do the 2 and 3 represent. I know the 0 and 1 correspond to variables, but I'm not clear on the second part.

Any help would be appreciated thanks! :)
