Note the left-most column.
It would actually be wide enough to display a single character -- which is the entire contents of that column, it's the keyboard shortcut corresponding to each row -- except the idiotic margins are reducing the available space for the contents to the point that you can't see any of the contents. Thanks, margins.
Solutions:
- Get rid of these internal element margins.
- Make the elements wide enough to always hold at least (left-margin + letter-m + right-margin) pixels.
