print acsii characters in tabular format using char

I am writing a function that will receive a matrix of integers uint8 less than 129 as input agrument. And print it as acsii characters in tabular format using char

 function mychar(y)

if y > 129
    disp('Please enter less than 129.')
else
    x = char(uint8(y))
    table1 = uitable
    set(table1,'Data',x)
end

However, it said data must be a numeric, logic. Is that any codes I missed on above?

try this:

   function mychar(y)

if y > 129
    disp('Please enter less than 129.')
else
    x = char(uint8(y))
    table1 = uitable
    set(table1,'Data',{x})
end
