Ruby syntax in ActiveRecord

Question

I am currently doing the ruby on rails beginner tutorials and I do not understand the specific syntax of migrations.

class CreateArticles < ActiveRecord::Migration[7.0]
  def change
    create_table :articles do |t|
      t.string :title
      t.text :body

      t.timestamps
    end
  end
end

Specifically, I do not understand the syntax within the method change on line 3.

What does create_table refers to?

What does :articles means? Is it a symbol?

What is the |t| in this case referring to. To a new table?

Any context and deeper explanations of this code would be appreciated.
