Açıklamalar

yöntemi, RenderEndTag temel sınıfın HtmlContainerControl.RenderEndTag yöntemini çağırdıktan sonra ek biçimlendirme sağlar. Ek biçimlendirme, kapanış <table> etiketinden sonra bir satır dönüşü ekleyerek denetimin HtmlTable işlenmiş HTML'sinin okunmasını kolaylaştırır.

RenderChildren yöntemi öncelikle denetimin işlevselliğini HtmlTable genişleten denetim geliştiricileri tarafından kullanılır.
