AWS云形成胶水表可重用模板

Question

我的AWS模板中有很多资源类型AWS::Glue::Table。而且我不会在模板之间复制粘贴代码段。因此，想法是创建一个接受参数的可重用的嵌套堆栈。我做到了，但仍然存在一个问题。我不知道如何通过参数将列传递给此堆栈[{Type: string, Name: type}, {Type: string, Name: timeLogged}]-它是对象的数组。但是params接受唯一的字符串类型。

我试图做这样的事情： !Split [ "," , "{Type: string, Name: type}, {Type: string, Name: timeLogged}"]-但没有帮助
