PHPExcel additional text add to column - php

Question

I have PHPExcel plugin to generated excel which data came from database, how if I wanted to add in additional text into a column A during the loop, and column B remain untouched data as from DB?
For example column A in DB is
alex
andy
jennifer
when output to excel, I wanted to add #domain.com for each name behind, wich will become
alex#domain.com
andy#domain.com
jennifer#domain.com
Code:
$query = "SELECT mail_name, account_id FROM email ORDER BY mail_name ASC";
$headings = array('Email', 'Id');
if ($result = mysql_query($query) or die(mysql_error())) {
// Create a new PHPExcel object
$objPHPExcel = new PHPExcel();
$objPHPExcel->getActiveSheet()->setTitle('emailList');
$rowNumber = 1;
$col = 'A';
foreach($headings as $heading) {
$objPHPExcel->getActiveSheet()->setCellValue($col.$rowNumber,$heading);
$col++;
}
// Loop through the result set
$rowNumber = 1;
while ($row = mysql_fetch_row($result)) {
$col = 'A';
foreach($row as $cell) {
$objPHPExcel->getActiveSheet()->setCellValue($col.$rowNumber,$cell);
$col++;
}
$rowNumber++;
}

Keep in mind that $col++ is not going to work.
What about this way?:
// Loop through the result set
$rowNumber = 1;
while ($row = mysql_fetch_row($result)) {
$objPHPExcel->getActiveSheet()
->setCellValue('A'.$rowNumber,$row['mail_name'].'#domain.com');
$objPHPExcel->getActiveSheet()
->setCellValue('B'.$rowNumber,$row['account_id']);
++$rowNumber;
}
