You can specify variables in a MATLAB table using tablename.varname. Cannot contain Inf or NaN. You must process grid vector data for use with the fit function by using prepareSurfaceData. If you use Curve Fitting app, you can select grid vector data and it automatically converts the data for you. If your data is in a MATLAB ® table, you do not need to use prepareSurfaceData. Here's some example code that fits a polynomial surface to random points. You can define your own fitting function if you like or check out the other fitTypes they have for surfaces.
