[php] PHPExcel set border and format for all sheets in spreadsheet

I'm currently trying to set all borders for my spreadsheet, also formatting such as autosize.

My code below is working, for sheet 1. All other sheets inside the spreadsheet are completely untouched. I've been trying to get it to work with all other sheets inside this spreadsheet but with no luck.

Any ideas on how i can global set the formatting so that all sheets have borders and autosize? The layout of all sheets in this spreadsheet are all the same. I'm exporting to XLSX file.

Cheers,

/**autosize*/
for ($col = 'A'; $col != 'P'; $col++) {
    $objPHPExcel->getActiveSheet()->getColumnDimension($col)->setAutoSize(true);
}


/** Borders for all data */
   $objPHPExcel->getActiveSheet()->getStyle(
    'A2:' . 
    $objPHPExcel->getActiveSheet()->getHighestColumn() . 
    $objPHPExcel->getActiveSheet()->getHighestRow()
)->getBorders()->getAllBorders()->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);



/** Borders for heading */
   $objPHPExcel->getActiveSheet()->getStyle(
    'A1:O1'
)->getBorders()->getAllBorders()->setBorderStyle(PHPExcel_Style_Border::BORDER_THICK);

EXTRA QUESTION: I've currently set headings. The headings do appear on sheet 1, but do not appear in any other sheets.. is it possible to show the headings in all sheets? The headings are set in Row 1. and the results are from Row 2 down.

$objPHPExcel->getActiveSheet()->setCellValue('A1', 'Asset_id');
$objPHPExcel->getActiveSheet()->setCellValue('B1', 'Asset_name');
$objPHPExcel->getActiveSheet()->setCellValue('C1', 'Asset_type');
$objPHPExcel->getActiveSheet()->setCellValue('D1', 'Asset_make');
$objPHPExcel->getActiveSheet()->setCellValue('E1', 'Asset_model');

To answer your extra question:

You can set which rows should be repeated on every page using:

$objPHPExcel->getActiveSheet()->getPageSetup()->setRowsToRepeatAtTopByStartAndEnd(1, 5);

Now, row 1, 2, 3, 4 and 5 will be repeated.

for ($s=65; $s<=90; $s++) {
    //echo chr($s);
    $objPHPExcel->getActiveSheet()->getColumnDimension(chr($s))->setAutoSize(true);
}
