Weird sorting behaviour ... sorting the column before

AfonsoGomes

Sorting works on the 4th column ("Flor") ... but after that the column "Descritor" (5th) sorts the column data "Flor" (4th) ... column "T. Fisio" (6th) sorts "Descritor" (5th) and so on ... what's wrong with my code? Been struggling with this for a bit!

```js
function especiesTodasCallback( nRow, aData, iDisplayIndex ) {

        $('td:eq(1)', nRow).html( '<a href="especies.php?idEspecie=' + aData[0] + '">' + aData[1] + '</a>' );

        if (aData[2] != 1) {
            $('td:eq(2)', nRow).html('<span class="cor-ad"><b>N</b></span>');
        } else {
            $('td:eq(2)', nRow).html('<span class="cor-jb">S</span>');
        }

        if (aData[3] == null) { aData[3] = "" }
        if (aData[4] == null) { aData[3] = "" }
        if (aData[3] != "" && aData[4] != "") {
            $('td:eq(3)', nRow).html( aData[3] + ' - ' + aData[4] );
        } else {
            $('td:eq(3)', nRow).html('<span class="cor-ad"><b>ND</b></span>');
        }

        if (aData[6] == null) {
            $('td:eq(4)', nRow).html('<span class="cor-ad"><b>ND</b></span>'); // aData[5] --> idDescritor
        } else {
            $('td:eq(4)', nRow).html(aData[6]); 
        }

        $('td:eq(5)', nRow).html( aData[8] );   // aData[7]  -> idTFis
        $('td:eq(6)', nRow).html( aData[10] );  // aData[9]  -> idFam
        $('td:eq(7)', nRow).html( aData[12] );  // aData[11] -> idOrdem
        $('td:eq(8)', nRow).html( aData[14] );  // aData[13] -> idSubClasse
        $('td:eq(9)', nRow).html( aData[16] );  // aData[15] -> idClasse
        $('td:eq(10)', nRow).html( aData[18] ); // aData[17] -> idSubDivisao
        $('td:eq(11)', nRow).html( aData[20] ); // aData[19] -> idDivisao

        return nRow;
    }
