convert double array in array string in table

it's possible to convert double array in array string in table ?

T.Strategy=[Sis.Sistema].';
data=[Sis.data];%[Eq.data];                        % N x size(Sis,2) array datetimes
T.DateF=data(1,:)';                    % start date is first each 
T.DateL=data(end,:)';                  % last date is end each

[r1]=arrayfun(@(s)find(s.dailyprof,1),Sis); %trovo il primo trade 
[r2]=arrayfun(@(s)find(s.dailyprof,1,'last'),Sis); %trovo ultimo trade
T.TradeF=arrayfun(@(s,i)s.data(i),Sis,r1)';
T.TradeL=arrayfun(@(s,i)s.data(i),Sis,r2)';

T.Strategy is array string.
T.DateF is array datetime
T.DateL is array datetime
T.TradeF is double array
T.TradeL is double array

Of course:

T = array2table(rand(5,2))

T = 5×2 table
      Var1        Var2  
    ________    ________

     0.51938     0.79195
    0.016597    0.088964
     0.79159     0.34445
     0.24275     0.62235
      0.9195     0.90204

T = convertvars(T,'Var1','string')

T = 5×2 table
       Var1         Var2  
    __________    ________

    "0.51938"      0.79195
    "0.016597"    0.088964
    "0.79159"      0.34445
    "0.24275"      0.62235
    "0.9195"       0.90204
