That router bit definitely needs a table. A temporary one as described would do.
If you want to buy or build a better one, here's my experience for selection of system or design, based on an older Axminster table thatI've had for many years.
1. A router lift is extremely convenient. On the Axminster one, get some drinking straws too, to blow dust out of the vertical adjuster Allen socket!
2. The inset T tracks for the fence are handy but not essential.
3. The split fence, however, is very useful. It means you can set it up either for routing profiles like a spindle moulder, or for jointing edges by recessing the input side by the depth of the cut and setting the output side flush with the bit.
4. Mine does not have an enclosed box for the router itself. I would like one, with dust extraction built in. Mine gets shavings everywhere and is a pain to clean up.
5. Mine has shelves but no built-in cupboards or drawers. This would have been useful, as there is a large number of bits, tools and accessories that you need to store with the router.
The new Axminster one,
