Hi! I'm trying to use context menu to enable row removing from uitable by following an example here:

function tableApp
fig = uifigure;
tbl = uitable(fig);
tbl.Position = [20 20 400 300];
tbl.Data = randi(10,[10 4]);
cm = uicontextmenu(fig);
m = uimenu(cm);
m.Text = "Delete Row";
tbl.ContextMenu = cm;
m.MenuSelectedFcn = @deleteRow;
cm.ContextMenuOpeningFcn = @(src,event)toggleVisibility(src,event,m);
end
function deleteRow(src,event)
tbl = event.ContextObject;
row = event.InteractionInformation.Row;
tbl.Data(row,:) = [];
end
function toggleVisibility(src,event,m)
row = event.InteractionInformation.Row;
rowClicked = ~isempty(row);
m.Visible = rowClicked;
end

However, I run into this problem:

>> tableApp
Invalid use of operator.

Error in tableApp>toggleVisibility (line 23)
