PHPExcel - How to apply borders to dynamic range of cells loaded from
mysql data

I tried all mentioned here below to no success. I need borders around the
data body/cells, excluding the headers row. Range starts from cell A2 to
the E as the last column & its rows. Data goes up to 4000 records or more
sometimes. I even increased the WAMP's php.ini execution timeout to 300
for test.
Following lines work fine if each one was used only and separately, if all
together, ends up with Fatal error of timeout 30 seconds!
$objPHPExcel->getActiveSheet()->getStyle("A".($rowNumber-1))->applyFromArray($styleBordersArray,
False);
$objPHPExcel->getActiveSheet()->getStyle("B".($rowNumber-1))->applyFromArray($styleBordersArray,
False);
$objPHPExcel->getActiveSheet()->getStyle("C".($rowNumber-1))->applyFromArray($styleBordersArray,
False);
$objPHPExcel->getActiveSheet()->getStyle("D".($rowNumber-1))->applyFromArray($styleBordersArray,
False);
$objPHPExcel->getActiveSheet()->getStyle("E".($rowNumber-1))->applyFromArray($styleBordersArray,
False);
Folllwoing line does not work with Fatal error of timeout 30 seconds!
$objPHPExcel->getActiveSheet()->getStyle("A".($rowNumber-1).":E".($rowNumber-1))->applyFromArray($styleBordersArray,
False);
Folllwoing line works fine, but is not the desired layout!! Just tried to
see.
$objPHPExcel->getActiveSheet()->getStyle("A".($rowNumber-1).":C".($rowNumber-1))->applyFromArray($styleBordersArray,
False);
Folllwoing line does not work with Fatal error of timeout 300 seconds with
increased php.ini!
$objPHPExcel->getActiveSheet()->getStyle("D".($rowNumber-1).":E".($rowNumber-1))->applyFromArray($styleBordersArray,
False);
