Ask HN: How to handle jealousy and tensions at work place?

I joined team 6-7 months back and one of colleague attitude was very bad from starting. We work in open cabin with all teams and I have two fights with one of my colleague. It is affecting my reputation and image in company. Most of my managers are around when these fights(orally not discussion) happen. She(have more experience) is jealous of me and do not agree with technical points. She pointed some things in my work four days back and on profiling I showed her she was wrong. She do not take things constructively and keep on fighting on the results also. She took that thing on ego. Today she made changes in framework which I have written. She asked for help from me and I corrected her code with some other changes. She keep on arguing why you removed other code. I told her from design perspective it is not responsibility of this framework and we should not put code in this framework. But she keep on arguing and do not listen to me. At end my manager listened to boths points (which is not very technical) also sided with me. But because of ego she keeps on arguing and pushed her code to repo. I tried to discuss constructively and productively in starting but she takes things on ego and do not listen to my points. As technically she was wrong, but these fights is affecting my reputation and image in company. Also it is very immature to fight on these things. I do not take care about code etc but these fights shows immaturity. What should I do and how to handle things in future. She do not have very technical knowledge despite her experience and do not listen and made points constructively and also tries to dominate in discussion.
