guimatlab数组表格_MATLABGUI表格（uitable）的增删操作这⼏天，查看了很多的MATLAB GUI 表格的操作，发现都没有⼀个完整的增删改的帖⼦。于是在我⾃⼰摸索下，⾃⼰搞出来了，增删操作。接下来就分享给⼤家！
界⾯布局：
表格的tag： uitable1
添加电价的tag：addEle
删除电价的tag：delEle
⾸先建⽴⼀个 newData.mat，⽤于存放表格数据：
在打开窗体的时候，加载 newData.mat ⽂件，并且显⽰：
添加数据，我是通过 对话框来实现的:
代码：
增加功能就完成了。接下来是删除功能：
1.删除功能，需要⽤到 表格的⼀个回调函数 CellSelectionCallback:
2.删除功能;
全部代码：
function varargout = demo(varargin)
% DEMO MATLAB code for demo.fig
% DEMO, by itself, creates a new DEMO or raises the existing
% singleton*.
%
% H = DEMO returns the handle to a new DEMO or the handle to
% the existing singleton*.
%
% DEMO('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in DEMO.M with the given input arguments.
%
% DEMO('Property','Value',...) creates a new DEMO or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before demo_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to demo_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one % instance to run (singleton)".
