The options MeshRange works if the array is evenly spaced.

data= Table[{x,y,x^2+y^2},{x,-4,4},{y,-5,7}];

Extract array of z values

dataz =data/.{__,z_?NumberQ}->z

Get the x and y ranges


Use ListPlot3D with MeshRange ->mr;

ListPlot3D[dataz, MeshRange->mr];

If we have an uneven rectangular grid we can make an interpolation function
for data and plot that: for example




If the points are not on a rectangular grid then the function
from the standard add-on
can be used.
