How to a plot a surface from excel sheet XYZ

I have an excel sheet (attached) and I want to plot a smooth XYZ surface from this data.

IMPORTANT NOTE:

Originally, both X & Y go from 0 to 0.5. However, some points were outliers and I needed to remove them, so I ended up with this data.

This is a screenshot:

T = readtable('https://in.mathworks.com/matlabcentral/answers/uploaded_files/791474/excel-surface.xlsx')

T = 2401×3 table

    0.04    0.01    1.85
    0.03    0.02    1.85

x = T.(1) ;
y = T.(2) ;
z = T.(3) ;


xi = linspace(min(x),max(x));
yi = linspace(min(y),max(y)) ;

[X,Y] = meshgrid(xi,yi) ;

Z = griddata(x,y,z,X,Y) ;

pcolor(X,Y,Z)

Thanks for answer, I plotted a 3D surface using surf command and it worked.
