I have created a uitable with its last column has a popup menu in each cell. But whenever I select the content of any menu it does not hold (the cell stays blank). The code is

moves = [1:Dynamic_states(c),]';
loads = zeros(size(moves));
strokes = Strokes{c,1}';
start_time = zeros(size(moves));
duration = Durations{c,1}';
mode = {'idle' 'sleep' 'off'};
tabledata =[moves loads strokes start_time duration];  
columnname =   {'Move #', 'Load kg', 'Strokes mm', 'Start time', 'Duration sec','Mode'};
columnformat = {'char', 'short', 'short', 'short', 'short', mode};
columneditable =  [false true true true true true]; 
handles.Load_Data = uitable('Parent',AppTab,'Units','normalized','Position',[0.5 0.438 0.4913 0.3],'ColumnWidth','auto','Data', tabledata,'ColumnName', columnname,'ColumnFormat', columnformat,'ColumnEditable', columneditable,'RowName',[] ,'BackgroundColor',[.7 .9 .8],'ForegroundColor',[0 0 0]);

Note: The creation of the uitable is inside a for loop so please avoid using functions to solve this problem

@Adam: The cell in the ColumnFormat create the popup menus in a uitable.

I do not see a reason to avoid a function to solve the problem. You can call functions from inside loops without any problems.

Ah yes, I see now. I missed the mode line. It's a while since I've created a uitable!

在 MATLAB Online 中打开

When I run you code and select an entry in the popup menu, Matlab shows the warning:

Warning: Table data is not editable at this location.

A guess: The Mode is missing in the tabledata. Try this:

mode        = {'idle' 'sleep' 'off'};
modedata    = cell(size(moves));
modedata(:) = {'idle'};  % Default value
tableValue  = num2cell([moves, loads, strokes, start_time, duration]);
tableData   = cat(2, tableVlaue, modedata);

Now the popups have default values and can be edited.
