Can you explain what's going on in this Ruby code?

I'm trying to learn Ruby as well as Ruby on Rails right now. I'm following along with Learning Rails, 1st edition, but I'm having a hard time understanding some of the code.
I generally do work in C, C++, or Java, so Ruby is a pretty big change for me.
I'm currently stumped with the following block of code for a database migrator:
def self.up
create_table :entries do |t|
t.string :name
t.timestamps
end
end
Where is the t variable coming from? What does it actually represent? Is it sort of like the 'i' in a for(i=0;i<5;i++) statement?
Also, where is the :entries being defined at? (entries is the name of my controller, but how does this function know about that?)
