Help to carry out Modal

good I have a table which loads data obtained from a database to modify sent the value of the id by means of get via function url, now the problem I have it when I want to de-enable via modal, I do not know how I can pass the value of the id to the modal as it is done when modifying.

I leave screen print, source code and test page where I have the problem is in suppliers fc.comunidadcoc.com

Source code where I get data from the database

 <?php 
 include '../../db/conectar.php';

function listado_proveedores(){
    $conexion   = new connex();
    $seleccion  = "SELECT Proveedor.*,Estado.Descripcion_Estado FROM Proveedor inner join Estado on Proveedor.ID_Estado=Estado.ID_Estado order by Proveedor.ID_Estado DESC";
$consulta   = $conexion->query($seleccion);
//Función while para capturar uno a uno las filas resultantes de la consulta
$lista = "";
while($fila = $conexion->row($consulta))
{
  //concateno a la variable creada los resultados de la fila
  $id = $fila['ID_Estado'];
  $lista .= '<tr>
  <td>'.$fila['Rut'].'</td>
  <td>'.$fila['Razon_Social'].'</td>
  <td>'.$fila['Comuna'].'</td>
  <td>'.$fila['Descripcion_Estado'].'</td>
  <td><button type="button" class="btn btn-warning" onclick="editar('.$fila['ID_Proveedor'].')">Modificar</button></td>';
 if ($id ==0){
 $lista .='<td><button type="button" class="btn btn-info" onclick="eliminar('.$fila['ID_Proveedor'].')">Habilitar</button></td>
 </tr>';
 }
 if ($id ==1){
 $lista .='<td><button type="button" class="btn btn-info" onclick="eliminar('.$fila['ID_Proveedor'].')">Deshabilitar</button></td>
 </tr>';
 }
}
echo $lista;
$conexion->cerrar();
