matlab gui表格行标1234没有,关于matlab gui uitable如何显示字符的问题

1. uitable 不能输入字符么？ 为什么GUI运行后，输入字符，当单元格失去焦点时，单元格自动变为NaN了呢？

2. 在uitable的某个单元格 输入数字后，又删除了这些数字，单元格会显示NaN而不是空白的，为什么会这样呢？能不能重新显示空白的呢？

谢谢

自己的问题还是自己解决……

我的方法是：(虽然很笨)

1. 在CellEditCallback函数里添加：

function table_CellEditCallback(hObject, eventdata, handles)

% hObject    handle to table (see GCBO)

% eventdata  structure with the following fields (see UITABLE)

% Indices: row and column indices of the cell(s) edited

% PreviousData: previous data for the cell(s) edited

% EditData: string(s) entered by the user

% NewData: EditData or its converted form set on the Data property. Empty if Data was not changed

% Error: error string when failed to convert EditData to appropriate value for Data

% handles    structure with handles and user data (see GUIDATA)

r=eventdata.Indices;

dd = get(hObject,'Data');

dd(r(1),r(2)) = {eventdata.EditData};

2. 对于只能输入数字的一些，我是这样做的

function table_CellEditCallback(hObject, eventdata, handles)

% hObject    handle to table (see GCBO)

% eventdata  structure with the following fields (see UITABLE)

% Indices: row and column indices of the cell(s) edited

% PreviousData: previous data for the cell(s) edited

% EditData: string(s) entered by the user

% NewData: EditData or its converted form set on the Data property. Empty if Data was not changed

% Error: error string when failed to convert EditData to appropriate value for Data

% handles    structure with handles and user data (see GUIDATA)

b=str2num(eventdata.EditData);

r=eventdata.Indices;

if ~(isnumeric(b)&&isempty(b)==0)

% 如果不是数字，清空单元格

dd = get(hObject,'Data');

dd(r(1),r(2)) = cell(1);

set(hObject,'Data',dd)

end

这样虽然解决了输入-显示的问题 可是我们会发现 数据全都显示在cell的左侧 和默认输入时显示在右侧的不一样

不知道有没有牛人能用简单的方法解决这个问题呢？

谢谢
