Как да използвам bootstrap css таблици за показване на данни от MySQL таблици?

Опитайте това

<?php
  $hostname = '192.xx.xxx.xx';
  $username = 'Mitchyl';
  $password = 'root1323';
  $dbname = 'test';

  try {
    $dbh = new PDO("mysql:host=$hostname;dbname=$dbname", $username, $password);

    $sql = $dbh->prepare("SELECT * FROM increment");

    if($sql->execute()) {
       $sql->setFetchMode(PDO::FETCH_ASSOC);
    }
  }
  catch(Exception $error) {
      echo '<p>', $error->getMessage(), '</p>';
  }

?>

  <div id="content">

    <table>
      <?php while($row = $sql->fetch()) { ?>
      <tr>
        <td><?php echo $row['column1_name']; ?></td>
        <td><?php echo $row['column2_name']; ?></td>
        <td><?php echo $row['column3_name']; ?></td>

        ...etc...

      </tr>
      <?php } ?>
    </table>

   </div>
