title: TF-Ranking transform data to ELWC - ExampleListWithContext form
body: <p>I have read all the guides, videos, and everything, but I have no idea how to convert my feature set to an ELWC datasheet format for TF-Rank ListWise problem. There is no description of this structure.</p>
  
  <p>For example, a students profile is:</p>
  
  <pre><code>Student ID  age  grade  math%   physics%   english%  art%  math_competit  language_competit Rank
    14588     16    k12     98      67         88      100   first_place        very_good       5
  </code></pre>
  
  <p>If I have 20 students in the same class, how can I transform this data to be able to make a listwise prediction for every grade ( theoretically in every grade has 3 class with 20 students)</p>
