We can add support for styling table cells.

In this case it doesn't seem reasonable to approach the problem with our usual "closed set of styles" (like image "full" and "aside" styles). Instead, we need a full flavored option.

One way to imagine it would be a button "cell properties" in a table toolbar. It would open a bigger panel where you could choose border style, border width, cell size, alignment (v and h), background color, border color.
