MATLAB GUI表格（uitable）的增删操作

大家好，又见面了，我是你们的朋友全栈君。

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)".
