我有一个表格,其中填充了动态数据并处理打印我已经应用了一些分页符一切正常,但我需要在打印时显示每页下面的" 第1页3 "等分页.我试过用css但我只能用它打印当前的页码.有没有其他方法来实现它？这是我的代码

   body {
        counter-reset: page;
    }
    .page-count:after {
        counter-increment: page;
        content: "Page " counter(page) " of " counter(pages);
    }

我已将 service-worker.js 和清单添加到我的网站，并使用灯塔测试了页面，这表明我的网页已准备好向用户显示“添加到主屏幕”。但是，如果用户在第一次没有关闭提示的情况下关闭选项卡，提示不会显示两次。还有其他方法可以实现吗？。这是我的清单

{
  "short_name": "TestApp",
  "name": "Long Name",
  "icons": [
    {
      "src":"images/favicon-192.png",
      "sizes": "192x192",
      "type": "image/png"
    },
    {
      "src":"images/favicon-256.png",
      "sizes": "256x256",
      "type": "image/png"
    },
    {
      "src":"images/favicon-384.png",
      "sizes": "384x384",
      "type": "image/png"
    },
    {
      "src":"images/favicon-512.png",
      "sizes": "512x512",
      "type": "image/png"
    }                
  ],
  "start_url": "/",
  "background_color": "#fff",
  "theme_color": "#d2d2d2",
  "display": "standalone"
}

这是我的 service worker javascript 文件
