gridded data bilinear interpolation MATLAB

Question

I have a tabulated data

which I like to use bi-linear interpolation between data (orange highlight in image) in MATLAB. I don't know how to use interp1 or interp2.

if i assume that the blue row is x, and the blue column is y and the data between is k(x,y). so I have three vector and I am going to expand vector x and later vector y as well, to interpolate data.

would you please help me?

I'd appreciate any help and comment.
