uitable.m代码如下：
function varargout = uitable_3(varargin)
% UITABLE_3 MATLAB code for uitable_3.fig
% UITABLE_3, by itself, creates a new UITABLE_3 or raises the existing
% singleton*.
%
% H = UITABLE_3 returns the handle to a new UITABLE_3 or the handle to
% the existing singleton*.
%
% UITABLE_3('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in UITABLE_3.M with the given input arguments.
%
% UITABLE_3('Property','Value',...) creates a new UITABLE_3 or raises the
% existing singleton*. Starting from the left, property value pairs are
% applied to the GUI before uitable_3_OpeningFcn gets called. An
% unrecognized property name or invalid value makes property application
% stop. All inputs are passed to uitable_3_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu. Choose "GUI allows only one
% instance to run (singleton)".
