Currently, each column in a table reserves space to be able to show the column's related action buttons (e.g. edit/copy).
Due of this, tables can show far less number of columns and data per row without needing to scroll than possible, or needlessly result in cut columns' data and leads to a bad UX.
Changing the UI to show the buttons in a way that would not require this, will make table significantly more useful (e.g. tooltip, right click menu)
