How to 'dropdown' in every cell of a table in App Designer with numerical values for example 0.5, 0.7 and 1?

I want the user to choose only between those three values, how could I do it?

            t = readtable('Austria.xls');
            vars = {'Damage','G','k1','k2','k3','k4'};
            t = t(1:32,vars);
            extent = categorical(t.k1,{0.5,0.8,1.0});
            t.k1 = extent;
            
            app.UITable.Data = t;

I put something like this, but it is not working

I wanted something like this, but with numbers

It might be easier to build your own table from dropdown menus, instead of hacking the UITable to allow you to use a dropdown.

You could also use a UITable and validate input after a users enters it.
