İsimli Aralıklar için Formül Ayarlama JavaScript ile C++ kullanarak
Adlandırılmış Aralık için Formül Ayarlama
Excel uygulamasına benzer şekilde, Aspose.Cells API’leri, Range.refersTo özelliği kullanırken bir isimli aralık için formül belirleme yeteneği sunar. Bu özellik için birçok kullanım senaryosu olabilir, bunlardan birkaçını aşağıda detaylandırılmıştır.
Basit Formül Ayarlama Adlandırılmış Aralık için
Basit bir formül, aynı (veya farklı) çalışma sayfasındaki başka bir hücreye bir referans olabilir. Aşağıdaki örnek, yeni bir elektronik tablo oluşturur ve referansını başka bir hücreye ayarlar.

Karmaşık Formül Ayarlama Adlandırılmış Aralık için
Karmaşık bir formül, bir dinamik aralık veya farklı çalışma sayfalarındaki birden çok hücreye yayılan bir formül olabilir. Aşağıdaki örnek, bir değerin konumuna bağlı olarak INDEX işlevini kullanarak dinamik bir aralık oluşturur.
