We try to fix JabRef#8739.However,it turned out a failure.
Due to lack of UI implementation experience and poor project time management,we are unable to contribute quality source code within the required deadline.
We successfully built the JabRef project locally and were able to run it. But without careful reading of the project's documentation, and without communicating with the developers, and with a tight schedule (too much time taken up by other school assignments), We can only find a few classes that might be relevant to the question (such as Keyword, Keywords), but we have no idea how to make the Keywords in the item appear next to the corresponding item in the main column (and the color of the Keywords is different, like the issue Keyword tag on GitHub). It's also not clear how these keyword tags will lead to a list of all entries that contain the keyword tag (shown in the main column maintable).
All in all, we are sorry that we have not made any substantial contribution to this project.

From one month learning experience, I have learned the whole process of developing a open source project.I have learned how to search open source projects, and how to make contributions to them. I have learned some useful tools like github and learned how to push my own codes to those project. At the later part of the course, our group have tried to solve an issue of Jebref, which is an Open source project we are interested in. However , due to the lack of developing experience,we have failed to solve our own issue, but at least we tried.
