Could you give an example of what use case this is solving for you? What are you returning from your Trestle.config.display_methods instance method?

This just doesn't feel like the right way to achieve this but my mind is open.

[edgarMeinart]

use case example

# Document ActiveRecord model
class Document
  belongs_to :organization
end

# Organization ActiveRecord model
class Organization
  has_many :documents
end

# Trestle admin /documents_admin.rb
...
table do 
  column :organization, truncate: { length: 20 }
end
...

For the current situation - (for example) in case when name of the subject is long - it takes up an unreasonable width of cell

This minor fix will allow to use such helpers as "truncate" to limit the output
