hello,

I want to make a table within a form by making a new form\_tag. The  
following code in ApplicationHelper fails:

def tabular\_form\_for(name, object = nil, options = nil, &proc)  
concat("

", proc.binding)  
form\_for(name,  
object,  
(options||{}).merge(:builder =\> TabularFormBuilder),  
&proc)  
concat("

", proc.binding)  
end

But using this tag in my view, I get errors with my :errors, :name  
fields of the form.  
Any ideas how to make this custom tag work?

Use a form builder. See the api doc.
