MATLAB: How to display an array in uitable GUI when click “show table” button

uitable

Hi,
I want to show my 1×2 array in uitable by using one click button:
function button_show_table_Callback(hObject, eventdata, handles)
dat = [1 2 3 4 5];
set(handles.uitable_data, 'Visible', 'on');
h = uitable('Data', dat, 'ColumnFormat', 'numeric');
close(h);
guidata(hObject, handles);
Below is my error message: ColumnFormat must be a cell array
May I know what is the problem? Thank you.

Best Answer

1. 'ColumnFormat' needs to be a cell array, so use
h = uitable('Data', dat, 'ColumnFormat', {'numeric'});
2. It looks to me you already have a uitable in your GUI, why do you create another uitable? I think you should do:
set(handles.uitable_data, 'Visible', 'on');
set(handles.uitable_data, 'Data',dat, 'ColumnFormat',{'numeric'});
