I am trying to print a table on the console (using the table function) that displays both characters and numerical values in the same table. My current code is shown below. How do I make it such that I can remove the { and ' characters from all of the parameters in the "Name of Value" column? Any help would be greatly appreciated. Thank you

col = {'Name of value', 'Value'};
titles = {'Mileage (km)', 'Tire Pressure (bars)', 'License Points'}';
vals = [20000, 2.4, 3]';
configTable = cell2table([titles, num2cell(vals)], 'VariableNames', col);
disp(configTable)
         Name of value          Value
    ________________________    _____

    {'Mileage (km)'        }    20000
    {'Tire Pressure (bars)'}      2.4
    {'License Points'      }        3

Use categorical or char:

X = ["Mileage (km)"; "Tire Pressure (bars)"; "License Points"];
Y = [20000; 2.4; 3];
T = table(char(X), Y, 'VariableNames', ["Name of value", "Value"])
T = 3×2 table
       Name of value        Value
    ____________________    _____

    Mileage (km)            20000
    Tire Pressure (bars)      2.4
    License Points              3

One simple way is to convert them to categorical, but if you're doing something with that variable, extra care should be taken.

col = {'Name of value', 'Value'};
titles = {'Mileage (km)', 'Tire Pressure (bars)', 'License Points'}';
vals = [20000, 2.4, 3]';
configTable = cell2table([titles, num2cell(vals)], 'VariableNames', col);
configTable.(1) = categorical(configTable.(1));
disp(configTable)
       Name of value        Value
    ____________________    _____

    Mileage (km)            20000
    Tire Pressure (bars)      2.4
    License Points              3
