Good morning, I have a question about how to make the above inputs receive data from my database, for example: let's suppose I change something, but I just want to change a value to the cep (just an example) but to change it I need to know all the other values to not leave them blank, ie I want when I click on update the table be filled with the old values causing me to just have to edit: D 
<form action="editar.php" method="POST">
<table class="table table-striped">
<thead>
<tr>
<th>Cpf Novo</th>
<th>Nome Novo</th>
<th>Cep Novo</th>
<th>Rua Novo</th>
<th>Bairro Novo</th>
<th>Cidade Novo</th>
<th>Estado Novo</th>
<th>Ibge Novo</th>
</tr>
</thead>
<tbody>
<tr>
<td><input type="text" onclick="" class="form-control input-sm" id="cpf" name="cpf" required><br></td>
<td><input type="text" class="form-control input-sm" name="nom" required><br></td>
