Ruling. — The ruling of the court must be given immediately after the objection is made, unless the court desires to take a reasonable time to inform itself on the question presented; but the ruling shall always be made during the trial and at such time as will give the party against whom it is made an opportunity to meet the situation presented by the ruling.
