Some comments,

You are using $b, which is a global variable. What is the use case? If
you are in the top level (no classes or methods) you don't need that.
In order to give better advice we would like to know which kind of
object is $b or what is returned by the method $b.table. If it's an
array of string arrays, you can do this:

table = $b.table(:id, /grid/)
table.each do |row|
  if row[3] == "text" #arrays start at 0
    puts row[4]
  end
end

Let us know if this works for you, or moves you in the right direction.

Jesus.
