$data = $pdo->query("SELECT * FROM t")->fetchAll();
if ($data) {
    echo "<table><tr>";
    foreach (array_keys($data[0] as $col)) {
        echo "<th>$col</th>";
    }
    echo "</tr>";
    foreach($pdo->query("SELECT * FROM t") as $row) {
        echo "<tr>";
        foreach ($row as $col) {
            echo "<td>$col</td>";
        }
        echo "</tr>";
    }
    echo "</table>";
}
