The users list is not a table, it is a list (UL / LI elements). By default it shows one user per row. Via CSS you can make it be displayed as a grid/table if you like. If you want a very custom user list you can create a plugin. I attach 2 screenshots of a sample user list transformation (1 minute work with CSS).

I will explain to you what may happened.

There is no delete button for translations. A translation gets deleted when the value is empty. When saving an article, or whatever, the translations system checks the strings that have been submitted for all languages. If the value for a language is empty, or not provided, it is marked for deletion.

en: Hello
el: Γειά
de: Hallo
it: Ciao

If you set de = "" (empty) then the corresponding translation will be deleted from the database.

Example
You have an article title in 4 languages, de, en, it, es
You unpublish Italian language (it)
You go and edit the article. As Italian is unpublished only values for de, en and es get proceeded (there is no "it"). Therefor the saved in database value for it is empty and so gets deleted.
When you re-enable Italian language and go to edit the same article you will see that there is no value for the "it".

If you lost many translations due to the above reason it means that you have the language set to OFF for a long time and in the meanwhile you edit many items.
This is absolutely normal behavior and this is how the translations system works. The deletion of empty/unused strings is in order to remove items from the database not needed any more.

Switching ON and OFF language does not affect translations saved in database. What can mess up things is changing the default language. This creates an inconsistency in translations table.
