PhpSpreadsheet 导出图片到 Excel

使用 Laravel Excel 3.1 版本来做导出图片到 Excel 的功能没有成功，后来作者回复了相关的写法 点击查看 因为回复的时候已经用 PhpSpreadsheet 实现了，所以没有再尝试 Laravel Excel 的写法

以下是 PhpSpreadsheet 导出部分的代码

    public function export($data)

        //设置sheet的名字  两种方法
        $sheet->setTitle('phpspreadsheet——demo');
        $spreadsheet->getActiveSheet()->setTitle('Hello');
        //设置第一行小标题
        $k = 1;
        $sheet->setCellValue('A' . $k, '问题');
        $sheet->setCellValue('B' . $k, '选项');
        $sheet->setCellValue('C' . $k, '答案');
        $sheet->setCellValue('D' . $k, '图片');

        // 设置个表格宽度
        $spreadsheet->getActiveSheet()->getColumnDimension('A')->setWidth(16);
