Ah, yeah. SMW doesn't have a good entry point.

There's actually no relationship between template params and SMW properties except by convention, and the shop params have their own thing going on which pre-dates SMW. To see what properties are available for a page, click on "Browse Properties," which on desktop is in the left-hand nav under User. For something like <a href="/wiki/Memory_of_Moonlight" title="Memory of Moonlight"><img alt="" src="/w/images/thumb/4/47/Moon.png/20px-Moon.png" decoding="async" width="20" height="26" srcset="/w/images/thumb/4/47/Moon.png/30px-Moon.png 1.5x, /w/images/thumb/4/47/Moon.png/40px-Moon.png 2x" /></a> <a href="/wiki/Memory_of_Moonlight" title="Memory of Moonlight">Memory of Moonlight</a>, you'll see Bought For and Sells For properties that point to values and shops.

Turning that into a table like what you have is... even more complicated. Those Properties are Records, which have their own extra level of indirection. I can probably throw a prototype together over the course of the week, though.
