Is it that this example is too trivial or is it that Matlab is not good at it?

I think the unstack function might help you out. I have written a small example using your data:
month = categorical({'Jan';'Jan';'Feb';'March'});
person = categorical({'John';'Mike';'John';'Mike'});
spendings = [100;50;75;40];
T = table(month,person,spendings)
u = unstack(T,'spendings','person')
I think you can customise it according to your needs.
Hope this helps!

The orginal table has dd/mm/yyyy not month. This is the point.

You can utilize the month and datetime functions to tweak them to your required format.
a = month(datetime('1/1/2020','InputFormat','dd/MM/yyyy'),'shortname')
The above line returns the Month in 'Mmm' format, for instance January as 'Jan'. You can tweak some of these properties to obtain the required values which best suits your requirements.
