no output from sensor
The second datasheet tell, that the preconfigured version doesn't need serial programming, which could be already guessed from the existence of a datasheet that doesn't even mention the digital interface.
The table doesn't "work" in a processor, you have to choose a suitable linearization method according to your application requirements. The table could be used as base of a lookup table with linear interpolation. I think, that a second or third order polynomial would result in less numerical effort. Using 6th order, as given in the datasheet seems absurd for a fairly linear characteristic, and also inappropriate considering the sensors specified accuracy.
