Set cell width only for some cells

[bt-nn]

I found
$writer->writeSheetHeader('Sheet1', $header, $col_options = ['widths'=>[10,20,30,40]] );
which worked as expected
but when i try
$writer->writeSheetHeader('Sheet1', $header, $col_options = ['widths'=>[null,null,null,40]] );
only the last col is displayed.
Adding a if would be a fix for that

	protected function initializeSheet(...) {
		...
		if (!empty($col_widths)) {
			foreach($col_widths as $column_width) {
				if($column_width) { // <-- NEW LINE
					$sheet->file_writer->write('<col collapsed="false" hidden="false" max="'.($i + 1).'" min="'.($i + 1).'" style="0" customWidth="true" width="'.floatval($column_width).'"/>');
				} // <-- NEW LINE
                		$i++;
			}
		}
