在使用PhpSpreadsheet出现空行导入的问题

public static function excelToArray($filePath)

    {

        $spreadsheet = IOFactory::load($filePath); // 载入excel表格
                
        $worksheet = $spreadsheet->getActiveSheet();

        $highestRow = $worksheet->getHighestRow(); // 总行数
            
        $highestColumn = $worksheet->getHighestColumn(); // 总列数
            
        $highestColumnIndex = Coordinate::columnIndexFromString($highestColumn);

        $data = [];


        for ($row = 2; $row <= $highestRow; ++$row) { // 从第二行开始
            
            $i = 0;

            $row_data = [];

            for ($column = 1; $column <= $highestColumnIndex; $column++) {

                $row_data[] = $worksheet->getCellByColumnAndRow($column, $row)->getValue();

                $i++;

            }

            if(!implode('',$row_data)){

                //删除空行
                
                continue;

            }

            $data[] = $row_data;

        }

        return $data;

    }
