Codeigniter & PHPexcel font size not changing on the first row - codeigniter

Question

When I create a phpexcel document I have set a custom font size.
For some reason the font sizes not changing on the first row.
Question: How to make sure that all rows have the same size including the header row
I have the code in a foreach loop on main controller but miss the first row of cells.
$styleArray = array(
'font' => array(
'size' => 15,
'name' => 'Candara'
));
$objPHPExcel->getActiveSheet()->getStyle('A' . $excelrow . ':D' . $excelrow)->applyFromArray($styleArray);
$objPHPExcel->getActiveSheet()->getStyle($objPHPExcel->getActiveSheet()->calculateWorksheetDimension())->applyFromArray($styleArray2);
Controller
<?php
class Events extends MX_Controller {
public function generate_excel() {
$query = $this->db->get('event');
$excelresults = $query->result_array();
require (APPPATH . 'third_party/PHPExcel-1.8/Classes/PHPExcel.php');
require (APPPATH . 'third_party/PHPExcel-1.8/Classes/PHPExcel/Writer/Excel2007.php');

$objPHPExcel->getProperties()->setCreator("");

$objPHPExcel->setActiveSheetIndex(0);
$objPHPExcel->getActiveSheet()->SetCellValue("A1", 'Event');
$objPHPExcel->getActiveSheet()->SetCellValue("B1", 'Event Title');
$objPHPExcel->getActiveSheet()->SetCellValue("C1", 'Event Date');
$objPHPExcel->getActiveSheet()->SetCellValue("D1", 'Event Start Time');
$objPHPExcel->getActiveSheet()->getPageSetup()->setOrientation(PHPExcel_Worksheet_PageSetup::ORIENTATION_LANDSCAPE);
$objPHPExcel->getActiveSheet()->getPageSetup()->setPaperSize(PHPExcel_Worksheet_PageSetup::PAPERSIZE_A4);
$objPHPExcel->getActiveSheet()->setPrintGridlines(TRUE);
$objPHPExcel->getActiveSheet()->getRowDimension(1)->setRowHeight(-1);
$excelrow = 2;
foreach ($excelresults as $excelresult => $excelvalue) {
$styleArray = array(
'font' => array(
'size' => 15,
'name' => 'Candara'
));
$objPHPExcel->getActiveSheet()->getStyle('A' . $excelrow . ':D' . $excelrow)->applyFromArray($styleArray);
if (!empty($excelvalue['fill_color'])) {
// Set the fill style
$objPHPExcel->getActiveSheet()->getStyle('A' . $excelrow . ':D' . $excelrow)->getFill()->setFillType(PHPExcel_Style_Fill::FILL_SOLID);
// Set the colour for the fill
$objPHPExcel->getActiveSheet()->getStyle('A' . $excelrow . ':D' . $excelrow)->getFill()->getStartColor()->setRGB($excelvalue['fill_color']);
$styleArray1 = array(
'font' => array(
'color' => array('rgb' => $excelvalue['font_color']),

);
$objPHPExcel->getActiveSheet()->getStyle('A' . $excelrow . ':D' . $excelrow)->applyFromArray($styleArray1);
$objPHPExcel->getActiveSheet()->getStyle('A' . $excelrow . ':D' . $excelrow)->getAlignment()->setIndent(2);

$objPHPExcel->getActiveSheet()->SetCellValue("A" . $excelrow, $excelvalue['event']);
$objPHPExcel->getActiveSheet()->SetCellValue("B" . $excelrow, $excelvalue['event_title']);
$objPHPExcel->getActiveSheet()->SetCellValue("C" . $excelrow, $excelvalue['event_date']);
$objPHPExcel->getActiveSheet()->SetCellValue("D" . $excelrow, $excelvalue['event_start_time']);
$excelrow++;
}
///exit();
$filename = 'Bowling-Events-For-' . date('Y') . '.xlsx';
$objPHPExcel->getProperties()->setTitle("Riwaka Bowling Club Events");
