The current format of showing review history works fine without bug. But, we should intend to change the format of that page to add some more precise.
We are showing the reviewer name in the review history. I think there is no need of showing that, as the reviewer is seeing his/her own history.
We should remove that and get some more space for other reasonable details. We can also have titles for the details showing on like post, action, time, etc. Provided screenshot is for suggested edit review history. We can have unique format changes for each review type.
