No pin table on the sheet. A pad pattern with VDD, DI and GND on one edge and DO alone on the other is unlike every other package in the catalogue (new template tpad-3332).

Outline and pin positions checked against the manufacturer datasheet (C42400839 XL-3332RGBC-WS2812B p11 (top and bottom views with labels VDD, DI, GND, DO); the XS sheet p11 is the same). The sheet has NO pin table and prints no pin numbers. Top view: VDD, DI and GND down the left edge (green mark at GND), DO alone on the right edge; numbers here are a catalogue convention. Pad sizes estimated from the drawing; the bottom view is the mirror image (VDD top, DO left, DI right, GND bottom). What this means.
