With Laravel Excel, it's easy to add a border to a cell:
$sheet->cell('A1', function($cell) {
$cell->setBorder('none', 'none', 'thin', 'none')
});
It's easy to add a border to a row too:
$sheet->row(3, function($row) {
$row->setBorder('none', 'none', 'thin', 'none')
});
But I did not found anything about column (maybe I did not search well). Is it possible to add a border (or some other style) to a whole column?
