Subject: Block variable - How is it read in English?

Following the "Ruby on Rails Tutorial", and under section "6.1.1
Database migrations"
http://railstutorial.org/chapters/modeling-and-viewing-users-one#top

There is the following migration:

class CreateUsers < ActiveRecord::Migration
  def self.up
    create_table :users do |t|
      t.string :name
      t.string :email
.
.
.

How do we read this line in English?

create_table :users do |t|

Why should we write the following line with "t."?

t.string :name

I know that block variables are used to pass parameters, but what is it
trying to tell us here?

So the "do |t|" part is actually the part that is confusing me.

Any clarifications would be appreciated.

Thanks.
