我的Scrapy代码只是在爬网（Debug:Crawled（200）），但没有爬网任何数据

Question

我的Scrapy代码只是抓取网页上的链接，但没有抓取任何数据。实际上，我正试图为我的项目抓取一些有关冠状病毒大流行的数据（比如国家名称、该国的城市，然后是病例数、伤亡人数等）。输出是调试：Crawled（200）在cmd中。我正试图从WorldMeters网站上抓取它（作为scrapy的新手，我知道的不多，并且提供了图像链接作为输出参考）

    countries = response.xpath("//td/a")
    for country in countries:
        country_name = country.xpath(".//text()").get()     
        country_link = country.xpath(".//@href").get()
        #To access the country link
        absolute_url = response.urljoin(country_link)
        yield scrapy.Request(url = absolute_url,callback = self.parse_country)     #Or do directly-->  yield response.follow(url = country_link)

    rows = response.xpath("(//table[@class = 'table table-bordered table-hover table-responsive usa_table_countries dataTable no-footer'])[1]/tbody/tr")
    for row in rows:
