$objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, $row, $value);
$col++;
}
$row++;
}
// Set active sheet index to the first sheet, so Excel opens this as the first sheet
$objPHPExcel->setActiveSheetIndex(0);
// Save Excel 2007 file
$objPHPExcel->setActiveSheetIndex(0);
header('Content-Type: application/vnd.ms-excel');

header ('Pragma: public'); // HTTP/1.0
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
$objWriter->save('php://output');
exit;

You already have the column name in your while loop where you call mysql_fetch_assoc. The $key value is the column name. So here is an updated portion of your code:
while($mrow = mysql_fetch_assoc($res)) {
$col = 0;
foreach($mrow as $key=>$value) {
// TODO: Do Something With the Column Name like set the row header. Note this crude code sets it every time. You really just want to do it the first time only.
$objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, 0, $key);
$objPHPExcel->getActiveSheet()->setCellValueByColumnAndRow($col, $row + 1, $value);
$col++;
}
$row++;
}
