How to create dependent fields on a record producer?

Good Morning,

I have created a custom table within my instance that has two fields, category and subcategory.  Subcategory requires a dependency on the category field.  I just want to make sure I am correct with the info I have found.  This is not possible on a record producer without scripting, I can only set a field dependency on the table form.  Not sure that it matters, but the category and subcategory is not related to incidents, they are related to facility requests at our company.
