Try putting your 3 script nodes in your body rather than in the head. It feels like an issue with how you're loading the modules.
尝试将您的 3 个脚本节点放在您的身体而不是头部。感觉就像你加载模块的方式有问题。

I had the same error and, at least for me, the error happened because I've used an element ID that doesn't exist.
我有同样的错误，至少对我来说，错误发生是因为我使用了一个不存在的元素 ID。
In this line:
在这一行：
var container = document.getElementById("example");
Make sure that ID of your div has the same name. In this case, it is "example":
确保您的 div 的 ID 具有相同的名称。在这种情况下，它是“示例”：
<div id="example"></div>
If container is undefinedwhen loading Handsontable, this error message will be displayed.
如果容器undefined在加载 Handsontable 时，将显示此错误消息。
