PHPExcel library splits comma separated values into new columns - php

Question

I'm trying to read a Excel spreadsheet with the PHPExcel library (1.7.9) and when the value of the field is comma separated the PHPExcel library puts de comma separated values into new colums instead of the same column.
Is this normal? Can I fix it?
this is the code of reader
<?php
require_once 'Classes/PHPExcel.php';
require_once 'Classes/PHPExcel/IOFactory.php';
$objPHPExcel = new PHPExcel();
$inputFileName = 'prueba.xls';
/** Identify the type of $inputFileName **/
$inputFileType = PHPExcel_IOFactory::identify($inputFileName);
/** Create a new Reader of the type that has been identified **/
$objReader = PHPExcel_IOFactory::createReader($inputFileType);
/** Load $inputFileName to a PHPExcel Object **/
$objReader->setReadDataOnly(false);
$objPHPExcel = $objReader->load($inputFileName);
$objWorksheet = $objPHPExcel->getActiveSheet();
echo '<table>' . "\n";
foreach ($objWorksheet->getRowIterator() as $row) {
echo '<tr>' . "\n";
$cellIterator = $row->getCellIterator();
$cellIterator->setIterateOnlyExistingCells(false); // This loops all cells,
// even if it is not set.
// By default, only cells
// that are set will be
// iterated.
foreach ($cellIterator as $cell) {
echo '<td>' . $cell->getValue() . '</td>' . "\n";
}
echo '</tr>' . "\n";
}
echo '</table>' . "\n";
?>
and this is a screenshot of excel spreadsheet
Thanks
