如何解决如何在 Google Apps 脚本中为电子邮件抄送字段使用变量？
我正在使用经过稍微调整的 this apps script 副本，使用包含各种数据的 Google 表格在 Gmail 中进行邮件合并。我在工作表中有一个列，供我也希望将电子邮件发送到的抄送收件人。但我不确定如何在 Apps 脚本中使用它。
我需要调整的代码如下，但是如何在表格中的抄送栏中添加抄送邮件？

感谢您的建议。
解决方法
获取抄送：
function getccs() {
const ss=SpreadsheetApp.getActive();
const sh=ss.getSheetByName('sheetname');
return sh.getRange(2,4,sh.getLastRow()-1,1).getValues().flat().join(',');
}
在这里试试：
GmailApp.sendEmail(row[RECIPIENT_COL],msgObj.subject,msgObj.text,{
htmlBody: msgObj.html,// bcc: 'a.bbc@email.com',cc: getccs(),from: 'myemail@email.co.uk',name: 'Custom From Name',// replyTo: 'a.reply@email.com',// noReply: true,// if the email should be sent from a generic no-reply email address (not available to gmail.com users)
attachments: emailTemplate.attachments,inlineImages: emailTemplate.inlineImages
});
