How to use a while to stock data in a table.

Hello, i want to know how i can stock datas in table mean while i'm using a while. In the table only the last data appears.

function BtnCalcular_Callback(hObject, eventdata, handles)

syms x;

Funcion=get(handles.EtxtFuncion,'String');

A=str2double(get(handles.EtxtInterA,'String'));

B=str2double(get(handles.EtxtInterB,'String'));

Tol=str2double(get(handles.EtxtTol,'String'));

e=100;

n=1;

while e>=Tol

Xr=(A+B)/2;

e=Xr-A;

fXr = double(subs(Funcion,x,Xr));

fXa = double(subs(Funcion,x,A));

sig=(fXr)*(fXa);

T=[A B Xr e sig];

set(handles.Tabla,'data',T);

if sig>=0

A=Xr;

else

B=Xr;

end

end

set(handles.ResRaiz,'String',num2str(A));
