I'm trying to make table with two identical screenshots, but the right column is wider then left one. Moreover, it depends on text in the row below, but I don't clearly understand, how it depends exactly.
Two simple examples:
 | 
:---:|:---:
Usage on GNOME 3 | Drag-and-drop on GNOME 3
 | 
:---:|:---:
Usage on GNOME 3 | Drag and drop on GNOME 3
The same text length, the same words... What's wrong with hyphens and how can I fix it?
