matlab 动态增加uitable内容

在利用matlab设计GUI程序时，uitable控件通常用来展示数据。而这些需要展示在GUI面板中的数据不是一层不变的，有的时候会动态地增加和变动。当数据需要动态增加时，需要考虑横向和纵向数据增加的情况。因此总结以下uitable数据横向和纵向动态增加的情况。

1、横向增加

设计一个GUI程序如下图所示：

主要的功能是横向地增加数据并在uitable内显示数据。主要效果如下所示：

                                        -----------------

代码如下：

% --- Executes on button PRess in pushbutton1.function pushbutton1_Callback(hObject, eventdata, handles)% hObject    handle to pushbutton1 (see GCBO)% eventdata  reserved - to be defined in a future version of MATLAB% handles    structure with handles and user data (see GUIDATA)%增加一列的按钮函数。对应的按钮为图中的【增加】按钮的功能
content1 = str2double(get(handles.edit1,'String'));content2 = str2double(get(handles.edit2,'String'));content3 = str2double(get(handles.edit3,'String'));content4 = str2double(get(handles.edit4,'String'));uitabledata = get(handles.uitable1,'data');handles.uitabledata = uitabledata;%将uitable内原来的数据保留下来，方便下次撤下动作时的数据恢复guidata(hObject,handles);%将content1-4和原来的数据组织成为uitable控件数据olddata = uitabledata;newcol = [content1 content2 content3 content4]';if isempty(olddata)    newdata = newcol;else    newdata = [olddata newcol];endset(handles.uitable1,'data',newdata);%将新增加的数据和原来的数据组成newdata，然后写入uitable1中。
% --- Executes on button press in pushbutton2.function pushbutton2_Callback(hObject, eventdata, handles)% hObject    handle to pushbutton2 (see GCBO)% eventdata  reserved - to be defined in a future version of MATLAB% handles    structure with handles and user data (see GUIDATA)%将刚才添加的那一列撤销，对应于图中的【重置】按钮的功能olddata = handles.uitabledata;set(handles.uitable1,'data',olddata);% --- Executes on button press in pushbutton3.function pushbutton3_Callback(hObject, eventdata, handles)% hObject    handle to pushbutton3 (see GCBO)% eventdata  reserved - to be defined in a future version of MATLAB% handles    structure with handles and user data (see GUIDATA)%将整个uitable清空，对应于图中的【清空】按钮的功能set(handles.uitable1,'data',[]);% --- Executes during object creation, after setting all properties.function uitable1_CreateFcn(hObject, eventdata, handles)% hObject    handle to uitable1 (see GCBO)% eventdata  reserved - to be defined in a future version of MATLAB% handles    empty - handles not created until after all CreateFcns calledset(hObject,'data',[]);%进入该GUI界面时，初始化uitable内容为空。
2、纵向增加
纵向增加数据并动态地在uitable控件中显示，即增加uitable内数据的行数，基本原理类似。
首先设计如下GUI界面：
其效果如下所示：
                                  .................................
具体程序如下：
% --- Executes on button press in pushbutton1.function pushbutton1_Callback(hObject, eventdata, handles)% hObject    handle to pushbutton1 (see GCBO)% eventdata  reserved - to be defined in a future version of MATLAB% handles    structure with handles and user data (see GUIDATA)%纵向动态增加数据，对应图中的【增加】按钮功能%首先将edit控件内的数据取出来content1 = str2double(get(handles.edit1,'string'));content2 = str2double(get(handles.edit2,'string'));content3 = str2double(get(handles.edit3,'string'));%取出原来uitable内容，并保存到handles内便于数据的重置操作uitabledata = get(handles.uitable1,'data');handles.uitabledata = uitabledata;guidata(hObject,handles);%将原来uitable的内容和新的内容组织成新数据olddata = uitabledata;newrow = [content1 content2 content3];newdata = [olddata;newrow]; %将新数据写入uitable内set(handles.uitable1,'data',newdata);% --- Executes on button press in pushbutton2.function pushbutton2_Callback(hObject, eventdata, handles)% hObject    handle to pushbutton2 (see GCBO)% eventdata  reserved - to be defined in a future version of MATLAB% handles    structure with handles and user data (see GUIDATA)%撤销刚才增加的那行数据，对应图中的【重置】按钮功能set(handles.uitable1,'data',handles.uitabledata);% --- Executes on button press in pushbutton3.function pushbutton3_Callback(hObject, eventdata, handles)% hObject    handle to pushbutton3 (see GCBO)% eventdata  reserved - to be defined in a future version of MATLAB% handles    structure with handles and user data (see GUIDATA)%清空该uitable控件内容，对应图中的【清空】按钮功能set(handles.uitable1,'data',[]);% --- Executes during object creation, after setting all properties.function uitable1_CreateFcn(hObject, eventdata, handles)% hObject    handle to uitable1 (see GCBO)% eventdata  reserved - to be defined in a future version of MATLAB% handles    empty - handles not created until after all CreateFcns calledset(hObject,'data',[]);%进入GUI页面程序并显示该uitable控件时，初始化其内的数据为空。
