How do I update table in App Designer using multiselect with listbox?

Hi! I having trouble with app designer in MATLAB and couldn't seem to find a solution. Please do help me!

I have a table data containing 49 columns and 63 rows.

    properties (Access = private)
         x = readtable('Table.xlsx'); % table read from formatted excel file
        
    end

Table do show up properly in app designer using following code

        function startupFcn(app)
            %loading data into table in app
            app.UITable.Data = app.x;
            % Change column name from imported data
            app.UITable.ColumnName = app.x.Properties.VariableNames;
            % make sure first column is fixed?
          
        end

And the listbox contains all the column names.

            % Create LocationsListBox
            app.LocationsListBox = uilistbox(app.UIFigure);
            app.LocationsListBox.Items = {'Location1','Location2','Location3','Location4','Location5','Location6','Location7','Location8','Location9','Location10','Location11','Location12','Location13','Location14','Location15','Location16','Location17','Location18','Location19','Location20','Location21','Location22','Location23','Location24','Location25','Location26','Location27','Location28','Location29','Location30','Location31','Location32','Location33','Location34','Location35','Location36','Location37','Location38','Location39','Location40','Location41','Location42','Location43','Location44','Location45','Location46','Location47','Location48'};
            app.LocationsListBox.ItemsData = {'2', '3', '4', '5', '6', '7', '8', '9', '10', '11', '12', '13', '14', '15', '16', '17', '18', '19', '20', '21', '22', '23', '24', '25', '26', '27', '28', '29', '30', '31', '32', '33', '34', '35', '36', '37', '38', '39', '40', '41', '42', '43', '44', '45', '46', '47', '48', '49', ''};
            app.LocationsListBox.ValueChangedFcn = createCallbackFcn(app, @LocationsListBoxValueChanged, true);
            app.LocationsListBox.Position = [22 47 255 114];
            app.LocationsListBox.Value = '2';

So I want to use listbox and multiselect locations and hence only the selected ones will be shown in the table like a filter function.

        % Value changed function: LocationsListBox
        function LocationsListBoxValueChanged(app, event)
            app.LocationsListBox.Multiselect='on';
            %enable multi select - hold shift or ctrl to select
            %match location name to app.UITable first row - location names
            selectedItems = app.LocationsListBox.ItemsData;
            noselections=length(selectedItems); %number of selections
            columnnamest=app.UITable.ColumnName;
            we=app.UITable.Data;
            for w=1:noselections
                y=cell2mat(selectedItems(w)); 
                y=str2double(y);
                app.UITable.ColumnName(w)=columnnamest(y);
                app.UITable.Data(:,w)=we(:,y);
            end
            if w<48 %deleteing excess
                app.UITable.Data(:,w:48)=[]; %Error stateent: Matrix index is out of range for deletion.
                app.UITable.ColumnName(:,w:48)=[]; 
            end
        end

Error statement:

Matrix index is out of range for deletion.

And also, the code generally does not select and update table.

Thank you for your help!
