DataTables JQuery插件和Rails表样式(DataTables JQuery plugin and Rails table styling)

 我上周刚拿起Ruby for Rails，我猜我的资产管道存在问题。 具体来说，我想覆盖Rails 4应用程序中DataTables表的默认样式，但更改custom.css.scss什么都不做。 样式显然来自dataTables / jquery.dataTables。 我所要做的就是对表格进行条纹处理，使交替的行具有不同的背景颜色，沿着以下行： 
 
tr.odd {
  background-color: pink;
}

tr.even {
  background-color: red;
}
 
 确切地说，这个datatables.css文件安装在我的应用程序的文件树中，以便我可以编辑或替换它，或者如果它不是本地的，我可以在哪里安装我自己的自定义文件来覆盖其规范？ 
 
 application.css： 
 
*= require_self
*= require_tree .
*= require jquery.ui.core
*= require jquery.ui.theme
*= require dataTables/jquery.dataTables
 
 注意：如果我删除了jquery.dataTables要求，我的custom.css.scss生效。 
 
 的Gemfile： 
 
# Use jquery as the JavaScript library
gem 'jquery-rails'

# JQuery UI
gem 'jquery-ui-rails'

# Datatables JQuery plugin
gem 'jquery-datatables-rails', git: 'git://github.com/rweng/jquery-datatables-rails.git'
 
 编辑： 
 
 请注意：我试图在.app / assets / datatables / jquery.dataTables.css下包含一个名为jquery.datatables.css的样式表，但Rails只是忽略它。 这个想法来自这篇文章 ，但要么我误解了作者所说的内容 ，要么在Rails 4中无效。 

I just picked up Ruby for Rails last week, and I'm guessing that I have some problems with the asset pipeline. Specifically, I want to override the default styling of the DataTables table in my Rails 4 application, but changing custom.css.scss does nothing. The styling is apparently coming from dataTables/jquery.dataTables. All I'm trying to do is to stripe the table so that alternating rows have different background colors, along the lines of:
 
tr.odd {
  background-color: pink;
}

tr.even {
  background-color: red;
}
 
Where, exactly, is this datatables.css file installed in my application's file tree so that I can edit or replace it, or if it's not local, where can I install my own custom file to override its specifications?
 
application.css:
 
*= require_self
*= require_tree .
*= require jquery.ui.core
*= require jquery.ui.theme
*= require dataTables/jquery.dataTables
 
Note: If I remove the jquery.dataTables requirement, my custom.css.scss takes effect.
 
gemfile:
 
# Use jquery as the JavaScript library
gem 'jquery-rails'

# JQuery UI
gem 'jquery-ui-rails'

# Datatables JQuery plugin
gem 'jquery-datatables-rails', git: 'git://github.com/rweng/jquery-datatables-rails.git'
 
Edit:
 
Just to note: I've tried to include a stylesheet called jquery.datatables.css under .app/assets/datatables/jquery.dataTables.css, but Rails just ignores it. The idea came from this article, but either I'm misinterpreting what the author is saying or it doesn't work in Rails 4.
