You can change - to another string with config.list.empty_field_text
To change for each column you could use some helper method overrides:
# controller
config.columns[:association].options[:empty_text] = 'click to edit'
# controller helper
def format_value(column_value, options = {})
if column_empty?(column_value) && options[:empty_text]
clean_column_value(options[:empty_text]
else
super
end
end
