Using PhpSpreadsheet I want to get (or set) the style for an entire sheet (not the whole spreadsheet)
I know the syntax for doing that for the whole spreadsheet
$spreadsheet->getDefaultStyle()->getFont()->setSize(100);
and for a single cell
$spreadsheet->getActiveSheet()->getStyle('A1')->getFont()->setSize(100);
but the same function for a whole sheet fails
$spreadsheet->getActiveSheet()->getStyle()->getFont()->setSize(100);
What is the correct syntax for styling a whole sheet?
