phpspreadsheet:如何在单元格和图像之间添加一些边距？

$spreadsheet = new \PhpOffice\PhpSpreadsheet\Spreadsheet();
$worksheet = $spreadsheet->getActiveSheet();
$cell = $worksheet->getCell('A1');

$fill = new \PhpOffice\PhpSpreadsheet\Style\Fill();
$fill->setFillType(\PhpOffice\PhpSpreadsheet\Style\Fill::FILL_SOLID)
     ->getStartColor()->setARGB('FF0000');

$border = new \PhpOffice\PhpSpreadsheet\Style\Border();
$border->setBorderStyle(\PhpOffice\PhpSpreadsheet\Style\Border::BORDER_THIN)
       ->getColor()->setARGB('000000');

$style = $cell->getStyle();
$style->getFill()->setFillType(\PhpOffice\PhpSpreadsheet\Style\Fill::FILL_SOLID)
               ->setStartColor($fill->getStartColor());
$style->getBorders()->getAllBorders()->setBorderStyle(\PhpOffice\PhpSpreadsheet\Style\Border::BORDER_THIN)
                                     ->setColor($border->getColor());
