title: Child rows (show extra / detailed information) with fixed columns
body: <p>I use Datatables plugin <a href="https://datatables.net" rel="nofollow noreferrer">https://datatables.net</a> </p>
  
  <p>How can I build row_details ( subtable ) <a href="https://datatables.net/examples/api/row_details.html" rel="nofollow noreferrer">https://datatables.net/examples/api/row_details.html</a> with left and right fixed columns <a href="https://datatables.net/extensions/fixedcolumns/examples/initialisation/left_right_columns.html" rel="nofollow noreferrer">https://datatables.net/extensions/fixedcolumns/examples/initialisation/left_right_columns.html</a>
  Like this 
  <code>datatables</code> <a href="https://jsfiddle.net/bagratzakaryan/bu9o7btL/8/" rel="nofollow noreferrer">https://jsfiddle.net/bagratzakaryan/bu9o7btL/8/</a>
  But in my case, I use server side and get an error with the datatables.js
