Surf plot Mesh Plot

Respected Sir,

I have three parameters P, Q and R all having 216 values and none is dependent on other (all are obtained independently)

Kindly let me know if I can plot surf/grid plot with these values. If not, any other plot except using trisurf command.

Excel file is attached herewith.

Thanks in advance.
