the question is : in pushbutton callback i read this code:
C=[h1 h2 h3 h4 h5 h6];
set(handles.uitable1,'DATA',C);

while i will change the value of C, when i push the pushbutton again, how to write C to sceond row?

current_data = get(handles.uitable1, 'data');
newdata = [current_data; C];
set(handles.uitable1, 'data', newdata);

@ww ww: I do not really understand, what you are asking for. What should appear in the first and second row at the third click?

@ww ww: But this is exactly what Walter's suggestion does.
By the way, I asked: "What should appear in the first and second row at the third click?" As far as I understand, the answer is: "The values create by the first and second click".
@Jan Simon but,it can not work,i took Walter Roberson advice,i mean,when i frist click,uitable show like this
this is my code
C=[h12 q3 pwf2 cy2 glr2 qd]; %one row
set(handles.uitable3,'DATA',C);
current_data = get(handles.uitable3, 'data');
newdata = [current_data; C];
set(handles.uitable3, 'data', newdata);
i mean,i have only one pushbutton,when i frist click,uitable show the first row,when i second click ,the data show in second row ,but,now when i second click, the data covered the first row.

For this to work the first time, the data property has to have been left initialized to its default [] .
For it to continue to work, the number of columns in C needs to be the same as the number of columns in the existing table.
I suspect some of your calculated h values might be empty, giving you a C shorter than previous rows. Use the debugger to find out.
