Get all the information of a tr

Good morning.

Within a <tr> tag there are about 15 <td> tags (information coming from the database), not all of them are being displayed. Each <tr> has a <td> with the option to click and a modal open with all the necessary information.

How do I get all the information that is present in <td> of each <tr> specified?

<?php $professoresListados = buscarProfessor($conexao);

    foreach($professoresListados as $professor)
    {
        echo "
            <tr>
                <td class='infoPhp' id='{$professor['idProfessor']}'>{$professor['idProfessor']}</td>
                <td><img src='../../../Accipiter/Imagens/Professor/noimage.jpg' class='imgTabela'></td>
                <td>{$professor['nomeProfessor']}</td>
                <td class='non759'>{$professor['emailProfessor']}</td>
                <td class='non759'>{$professor['cpfProfessor']}</td>
                <td style='cursor: pointer;' id='{$professor['idProfessor']}' class='atribSession' onclick='capturarId(this.id)'><i class='fa fa-sign-in' aria-hidden='true'></i></td>
            </tr>";
    }
?>  

The <td class='non759'> is not displayed to the user. But when you click on <td> of visualization a modal opens and all information is found. How to get all data from within <tr> ?
