I think that it would be best not to put anything in the crack, as
doing so almost guarantees that the edges can't close together to
where they were.

How about once the rest of the mill is fixed, drill and tap some holes in edges
of the table to install a pair of plates to hold the pieces together. Then use
the router to mill a recess bridging the crack, and an exact fitting splice
plate, with matching holes for rows of socket head cap screws

I forgot to say, this does seem like an avenue worth exploring.
Especially as the part is already conveniently mounted under a router
spindle. Th
The table can't be made worse. It needs replaced anyway, but if you can find a
person who can weld it without warping the alignment of the guides, it would
save a bunch of money. Some cast aluminum alloys just don't take well to being
welded. They either resist having the weld metal stick, melt
I'd pull the plate off the machine and weld it. Then mill it flat. It's
a router, not a mill.
The problem might be finding a local welder and mill that can handle a
piece that size. Handling costs can get pricey if you don't have your
own truck.

That's good on cast iron. I don't know that it works on aluminium?

Brazing with Aluminum Bronze would be the preferable alternative to welding.
Lock-N-Stitch pins are also another option. Advantage is it's a cold
process, but it's rather slow.

It's probably a bad idea, but I would think that it is worth at least
a try. You don't have a lot
