The table runs on to the right: 6 more columns after Reach. Scroll it sideways to read them.
The S-490 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 page "2024 New disc carbon road frame bicycle frameset CS-R01" (category Road Frame, Disc Brake, posted "Time:2024-11-08"; model_year 2024 from the title) is live and is not on the xmcarbonspeed.cc store. Under its "Geometry" heading: a letter drawing (T1 drawn horizontal from the seat tube line to the head tube top, so top_tube_effective; REACH and STACK to the head tube top; C1 seat tube; HT head tube; G fork length; A head angle; B seat angle; F fork offset; H BB drop; RC chainstay; FC front centre; WB) and the table, sizes "XXS-425 / XS-460 / S-490 / M-515 / L-540" (labels kept). The XXS and XS seat tube (C1 425, 465) and head tube (HT 97, 109) cells are printed in red, the rest in black; meaning not given. G fork length 373/372.8/373.8/373.6/372.8 (not in the schema). The spec text says "Size: XS/S/M/L" while the table has five sizes from XXS. The CS-R01 and the xmcarbonspeed.cc store's CS-R06 (xmcs-cs-r06) share the L-540 numbers (stack 572, reach 387, wheelbase 1000.7) and differ on the smaller sizes and the angles: kept as two frames. Spec: brake type disc, includes frame, fork, seatpost, UD weave, max tire 700*32C, thru axles front 100*12 rear 142*12, T700 Toray, weight (size L) frame 1000+/-30g, fork 390+/-15g, seat post 112+/-10g. Bike Insights holds one size ("Large") of the CS-R01. CLOSURE: the printed top tube closes against the table's own stack, reach and 73.3 deg seat angle on the XXS (1.6 mm) and the L (0.1 mm), but the XS, S and M top tubes are 6.0 to 6.1 mm shorter than those numbers give (S: 371 + 528 / tan 73.3 = 529.6 against 523.3): kept as printed (see seat_angle_check).
