推荐答案

你需要添加一个单元格内容的处理程序单击了事件。如果该列是您的链接列，则获取文档路径示例：（C：\ mydoc.txt）检查该给定路径上是否存在文件以避免错误，然后通过该特定文件类型所需的任何方式打开。



虽然我完全理解你的问题，但我不确定。如果你提供更多细节，那么它可能会变得更加清晰。

You will need to add a handler for the cell content clicked Event. If the column is your Link column then get the document path example: (C:\mydoc.txt) Check for the existence of the file at that given path to avoid errors and then open by whatever means are required for that particular file type.

I'm not certain though that I fully understand your question. If you provide more details then maybe it will become a little more clear.
