Surface Plot Excel Data

I have a file in excel with varying data in x, y & z independent of each other. How do I surface plot these ?? The A column is X data (shown in black), Row 1 is Y data (shown in Red) and the Z data is found out for each corresponding values of X and Y experimentally(shown in blue).
I did import the X and Y data from excel to matlab, also one of the Z data (column B) But not the entire Z data (blue). Any suggestions.

Z = num(2:end,2:end) ;

I tried to do the above but got the following error,

Data dimensions must agree.
Tried transposing but that isn't working also. Please help.

z = table2array(T) ;
surf(z)
