Ajax Table not Sorting

Ajax Table not Sorting

Hey guys, I am facing a problem after include Ajax on my website. Sorting is not working.
Not only sorting, but other stuff too. But I am sure if I figure out what is going on, I can solve the other problems.

This is what I am doing:
index.html:

    <div class="table-responsive">
      <table id="opcoesListTable" class="table table-sm table-borderless">
        <thead>
          <tr>
            <th>Cód.<br>Ação</th>
            <th>Cód.<br>Opção</th>
            <th class="text-center">Tipo</th>
            <th class="text-center">Estilo</th>
            <th class="text-center">Vencimento</th>
            <th class="text-right">Strike</th>
            <th class="text-right">Preço<br>Opção</th>
            <th class="text-right">Negócios</th>
            <th class="text-right">Volume</th>
          </tr>
        </thead>
      </table>
    </div>

main.js:

        $(document).ready(function () {
          $(document).ready(function () {
            $("#opcoesListTable").DataTable({
              processing: true,
              serverSide: true,
              order: [],
              ajax: {
                url: baseURL+'admin/opcoesAjax/getLists/',
                type: "POST"
              },
              columnDefs: [
                {
                  targets: [0],
                  orderable: false
                }
              ]
            });
          });
        });

opcoesListarAjax.php:

            }
        }
    
    }

Anyone know what I am doing wrong?

    Does whatever SQL abstraction layer you are using allow you to print out the SQL that is being generated? If so, then I'd suggest printing out the SQL at line 26 to see what it being built, and thus why it isn't sorting. That would be the starting point to debug your code.
