我在Google工作表上有一个简单的邮件合并脚本，可以正确发送电子邮件。我的邮件合并代码确实处理内嵌图像，但
1）它无法正常工作并显示“内嵌图像1”而不是实际的内嵌图像。在我的代码中，内嵌图像成为附件。
2）另外，如果我把占位符＆lt;＆gt; ＆LT;＆GT;一起（即使中间有空格或逗号），它显示发送错误消息：“无法调用方法”替换“未定义”。可能是因为如果占位符在同一行上，则替换名称是错误的。
当2个占位符在同一行时，请参阅以下图像以获取错误代码：
发送和实际电子邮件消息，其中“内嵌图像1”应该是图像所在的位置：
这是我在Google工作表上进行邮件合并的代码，它取代了＆lt;＆lt;＆lt;＆lt; ＆GT;＆GT;它与Google工作表中的列标题匹配，并与相应的值相匹配。有人可以就线内图像和占位符问题提出建议吗？非常感谢，谢谢！
