[dustymc]

I am reopening this, the global table styling makes other things overly difficult. Particularly

td,th {
	border: 1px solid black;
}
 

is too limited in scope, isn't compatible with other things I'd like to do (rotate headers to avoid a 50-character-wide column containing a small integer), and has essentially manifested as a bug.

I'm going next task and high priority to remove this from globals, then selectively re-implement where appropriate and requested.
