How do I use a simple array (ex. a = [1:1:5]) for the names of row variables in a table?

I find all the different data types in MATLAB to be extremely confusing and poorly documented, and as a result have spend an hour trying to answer this simple question. I know that it involves some conversion of the array to both a cell array AND and character vector, but can't figure it out. Thanks.

For example,

    rownames=arrayfun(@num2str,1:5,'uni',0);
    T=array2table(eye(5));  %fake table
>> T.Properties.RowNames=rownames
T =
    5×5 table
           Var1    Var2    Var3    Var4    Var5
           ____    ____    ____    ____    ____
      1    1       0       0       0       0   
      2    0       1       0       0       0   
      3    0       0       1       0       0   
      4    0       0       0       1       0   
      5    0       0       0       0       1
