I am new to matlab and I want to show my excel data as a table in axes in gui using GUIDE. I am reading the table from the excel sheet and trying to convert it into uitable and display it in axes. How can i do that?

function Emergency_selection_OpeningFcn(hObject, eventdata, handles, varargin)
% This function has no output args, see OutputFcn.
% hObject    handle to figure
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)
% varargin   command line arguments to Emergency_selection (see VARARGIN)

% Choose default command line output for Emergency_selection

    handles.output = hObject;

    % Update handles structure
    guidata(hObject, handles);

    %read the data from file
    %[num,txt,raw]=xlsread('C:\Users\abhijit\Desktop\mmajor.xlsx');
    %uitable1 =uitable(Emergency_selection,'Data',[num,txt,raw]);
    t=readtable('C:\Users\abhijit\Desktop\mmajor.xlsx');
    tab=uitable
    tab=t;
    %update the table
    set(handles.tab,'data',num,'ColumnName',txt);

    %update the plot
    plot3(handles.axes1, num(:,1), num(:,2), num(:,3));
  % UIWAIT makes Emergency_selection wait for user response (see UIRESUME)
  % uiwait(handles.figure1);

% --- Outputs from this function are returned to the command line.
function varargout = Emergency_selection_OutputFcn(hObject, eventdata, handles) 
% varargout  cell array for returning output args (see VARARGOUT);
% hObject    handle to figure
% eventdata  reserved - to be defined in a future version of MATLAB
% handles    structure with handles and user data (see GUIDATA)

% Get default command line output from handles structure
varargout{1} = handles.output;

Abhijit - since you are using GUIDE, why don't you just create a uitable (there, in GUIDE) and then populate it in your code? Do you know how many colummns of data will be in the table? Do you know their data types?
