The tinted row is the size drawn beside it. Press a size to draw it.The table runs on to the right: 6 more columns after Reach. Scroll it sideways to read them.
The L drawn to scale from the table, with no build on it. Stack and reach run from the bottom bracket to the top of the head tube; every size is solved from those two. One square is 100 mm.

How I read the maker's table
the Oi! is its non-assisted carbon aero gravel bike, "Toray T800 / T1000 carbon fiber | 15 mounting points | e-bike conversion", 6-7 kg complete, 40 mm tyre clearance). I am taking this to be the "Cosmo" of my list; that match is my guess. Letter keys read from the drawing: Cf seat tube (BB to top of seat tube, seat_tube_length), O top tube (drawn horizontal, top_tube_effective), Hs head tube, Ss deg head angle, Sc deg seat angle, C chainstay, WB, BB Drop, Fork Rake (fork_offset), Fork (length). Rows not in the schema: Recommended Rider Height 159-170cm / 168-176cm / 176-182cm / 182-190cm; Fork Length 400 / 400 / 400 / 400. The top tube closes on reach plus stack over tan of the seat angle to 0.1 mm on every size. STACK DATUM: not stated; head tube top assumed. MODEL YEAR: not printed (null). No Panda Podium, Geometry Geeks or 99 Spokes request was made.
