- @subjects.each do |s|
%tr

%td= s.name
%td= s.visible ? "Yes" : "No"
%td= s.pages.size

= link_to("Delete",{:action => "delete",:class => "action delete")
ERROR_MSG：
Illegal nesting: content can’t be both given on the same line as %td and nested within it.
解决方法
你只需要改变这个：
%td= link_to("Show",:class => "action show")
= link_to("Edit",:class => "action edit")
= link_to("Delete",:class => "action delete")
对此：
%td
= link_to("Show",:class => "action delete")
你还应该从tr缩进tds.
