MATLAB: Make a Table in UIAxes

app designerMATLABtable in uiaxesuiaxesuitable

Hi,

I am looking for a way to plot a Table directly in UIAxes,

This is my code:

                  fig = app.UIAxes;
                  dates = datetime([2016,01,17; 2017,01,20],'Format','MM/dd/uuuu');
                  m = [10; 9];
                  tdata = table(dates,m,'VariableNames',{'Date','Measurement'});
                  uitable(fig,'Data',tdata);

Unfortunately it is not working, and not showing error neither !

Thank you

Hm, that should throw an error (but I see that it doesn't).

The uitable should be a child of a "Figure object (default) | Panel object | Tab object | ButtonGroup object | GridLayout object" (parent info). You're setting it as a child of a uiaxes. You probably intended to set it has a child of the figure.

 uitable(app.UIFigure,'Data',tdata)
 % where app.UIFigure is your figure handle

However, if you're using app designer, the table should typically be created from within app designer and should already exist before you populate it with data. In that case,

 app.UITable.Data = tdata
 % where app.UITable is a handle to an existing uitable

MATLAB: App designer Table with input numbers of rows and columns

You can create properties and set the values using following code

properties (Access = private) 
        Property % Description 
        colonna=3; %columns 
        slice=2;  %rows 
    end

You can use following code to create table with the given number of rows and columns and with check boxes in each row.

methods (Access = private)  
        % Code that executes after component creation 
        function startupFcn(app) 
             
            fig = uifigure; 
            tdata = table('Size',[app.slice, app.colonna],'VariableTypes',["logical","string","string"]);  % use “logical” to get checkbox in first column 
            uit = uitable(fig,'Data',tdata,'ColumnEditable',[true false false]); %  columns can be editable if ColumnEditable is true  
            uit.Position(3) = 130; 
            uit.RowName = 'numbered'; 
        end 
    end

Hope this helps!

Hi,

Folllowing is the code and app design

    % Properties that correspond to app components
    properties (Access = public)
        UIFigure  matlab.ui.Figure

    % Component initialization

        function createComponents(app)
            % Create UIFigure and hide until all components are created
            app.UIFigure = uifigure('Visible', 'off');

            % Create Button
            app.Button = uibutton(app.UIFigure, 'push');
            app.Button.ButtonPushedFcn = createCallbackFcn(app, @ButtonPushed, true);
            app.Button.Position = [447 249 100 22];
            % Show the figure after all components are created
            app.UIFigure.Visible = 'on';
        end
    end
    % App creation and deletion
    methods (Access = public)
        % Construct app
        function app = app1
            % Create UIFigure and components
            createComponents(app)
            % Register the app with App Designer
            registerApp(app, app.UIFigure)
            % Execute the startup function
            runStartupFcn(app, @startupFcn)
            if nargout == 0
                clear app
            end
        end
        % Code that executes before app deletion
        function delete(app)
            % Delete UIFigure when app is deleted
            delete(app.UIFigure)
        end
    end
end

Error you are facing instantiates that the code is not able to access the camera object at that instant.

Hope it helps!!
