【问题描述】：

我编写了这段代码，以便可以将一些信息保存在 excel 文件中，但它会为每个用户运行多次，并且由于某种原因，它不会追加新行，而是删除旧行并写入新行。有人可以帮忙吗？

        // A new Excel Work Book
        var workbook = new Excel.Workbook();

        // Create a sheet
        var sheet = workbook.addWorksheet("Sheet1");


        // Add rows in the above header
        sheet.addRow(
          user_id: info.id,
          user_tag: username,
          followed_by: inform.username,
          followers: info.edge_followed_by.count,
          followings: info.edge_follow.count,
          biography: info.biography,
          category: info.business_category_name,
          external_url: info.external_url,
          external_lynx_url: info.external_url_linkshimmed,
          is_verified: info.is_verified,
        );

        // Save Excel on Hard Disk
        workbook.xlsx.writeFile("business_accounts.xlsx").then(function () 
          // Success Message
          alert("User Saved");
        );

【参考方案1】：

// A new Excel Work Book
        var workbook = new Excel.Workbook();

        // Create a sheet
        var sheet = workbook.addWorksheet("Sheet1");

        for (user of users) 
        // Add rows in the above header
        sheet.addRow(
              user_id: info.id,
              user_tag: username,
              followed_by: inform.username,
              followers: info.edge_followed_by.count,
              followings: info.edge_follow.count,
              biography: info.biography,
              category: info.business_category_name,
              external_url: info.external_url,
              external_lynx_url: info.external_url_linkshimmed,
              is_verified: info.is_verified,
            );
        

        // Save Excel on Hard Disk
        workbook.xlsx.writeFile("business_accounts.xlsx").then(function () 
          // Success Message
          alert("User Saved");
        );

所有用户只需要一个 excel 文件，因此只需要重复 addrow 函数。确保您只创建和编写一次。
