推荐答案

我只是无法理解它是如何成为一个问题。可以有不同的方式来实现这一目标。在最简单的情况下，您创建两个字符串列（不计算行标题），一个表示键，另一个表示值。在所有键值对的循环中，填写两列。这将需要几行代码。由于我不知道您是否要编辑数据，因此您需要至少使密钥列为只读，因为编辑密钥将是无效操作。根据值的类型，您可以编辑它们。

I just cannot understand how it can be a problem. There can be different way to achieve that. In simplest case, you create two string columns (not counting row headers), one representing keys, another one — values. In the loop by all key-value pairs, fill in both columns. It will take few lines of code. As I don't know if you want to edit data, you need to make at least the key column read-only, because editing a key would be invalid operation. Depending on the type of the values, you might be able to edit them.
