Excel，基于同一列的Excel表格的自动填充列

Question

我正在尝试自动填充列：

+-------+-----------------------+
| Name  |  Currently Employed?  |
+-------+-----------------------+
| John  |                       |
| Tom   |                       |
| John  |                       |
| John. | Yes                   |
+-------+-----------------------+

如果我将当前使用的第4行更新为是。我想查找所有其他实例并使用相同的值进行更新：

+-------+-----------------------+
| Name  |  Currently Employed?  |
+-------+-----------------------+
| John  | -> Yes                |
| Tom   |                       |
| John  | -> Yes                |
| John. | Yes                   |
+-------+-----------------------+

任何更改都应反映在名称的所有实例中，无论顺序如何。例如，如果：

+-------+-----------------------+
| Name  |  Currently Employed?  |
+-------+-----------------------+
| John  | -> No                 |
| Tom   |                       |
| John  | Yes                   |
| John. | Yes                   |
+-------+-----------------------+

然后：

+-------+-----------------------+
| Name  |  Currently Employed?  |
+-------+-----------------------+
| John  | Yes                   |
| Tom   |                       |
| John  | -> No                 |
| John. | -> No                 |
+-------+-----------------------+

这可能吗？
