Indicator Function Parameterization

[#1]

I am working with a model in JMP that used Column 36 (Day/time series) as continuos, and co-%cover is continous baseline data, and column 35 is nominal and a treatment identifier of which there are 7 treatments. My question is the for the Prob >|t| what is that comparing? is it comparing eveyrhting to treatment 7 which is not listed as a term here or treatment 7 the intercept??

I am interested in understanding this table better to better understand what it is telling me about this data.
