I love this. How about vertically centering things too?

Lines 7 to 13 in 755fdc2

	table.compare td {
	/* Vertically align entries in the astropy comparison table.
	* The `!important` property is to keep Documenter.jl's custom
	* themes from overriding things
	* */
	vertical-align: text-bottom !important;
	}

-    vertical-align: text-bottom !important;
+    vertical-align: middle !important;

Sweet!

For those weird hanging lines:

it looks like we need to sneak in an extra empty row:

<tr>
</tr>

Idk if there's a better way?
