Ran in:
Assuming all your entries are numeric, since you want to assign NaN, here is one way;
% create dummy table
Age = [38;43;38;40;49];
Height = [71;69;64;67;64];
Weight = [176;163;131;133;119];
T = table(Age,Height,Weight);
T
T = 5x3 table
Age Height Weight ___ ______ ______ 38 71 176 43 69 163 38 64 131 40 67 133 49 64 119
% assign NaN to 1st row
T(1,:) = array2table(NaN(size(T(1,:))));
T
T = 5x3 table
Age Height Weight ___ ______ ______ NaN NaN NaN 43 69 163 38 64 131 40 67 133 49 64 119
