How do I use a table to define temp sensor?

I have a SECU-3 Micro and are going to use a Bosch temp sensor.

I will have to define a temperature sensor table, but how do I create it, and where do I put it?

I have ticked the "Use table to define sensor's curve", but where do I go from here?

HI Jim, thank you for your question.
Following picture shows button which opens needed curve. This curve specifies function temperature vs voltage on the sensor.

If you know how resistance of sensor depends on temperature, then you can calculate voltage on the sensor. This can be done using voltage divider formula. Upper resistor is resistor inside the unit, with 5V applied to it. Bottom resistor is sensor's resistance. First, try default values, it maybe already ok.

Thanks for your great reply. I missed this feature (sorry) but understand what I have to do now.:)
