In ROR open link on a new tab, open another link through datatables using server side datatables

[].tap do |column|
      column << count
      links = []
      links << link_to("#{trainee.full_name}", profile_path(trainee.user.id)) 
      column << links 

This is traniees_datatables.rb file. when I click traniee name I want it to open in a new tab.

This work on index.slim file as

 td = link_to "#{trainee.full_name}", profile_path(trainee.user.id),target: "_blank", rel: "nofollow"

When I add target: "_blank", rel:"nofollow" in traniees_datatables.rb file shows an error.
