How to validate user input in a UITable between three values?

I just one the user gives numbers either 0.5, 0.7 or 1

function damage
    % Create table array
    t = readtable('Country.xls');
    vars = {'Damage','G','k1','k2','k3','k4'};
    t = t(1:32,vars);

    % Create UI figure
    fig = uifigure;

    % Create table UI component
    uit = uitable(fig);
    uit.Data = t;
%     uit.ColumnSortable = true;
    uit.ColumnEditable = [false false true true true true];
uit.CellEditCallback = @k1CheckCB;
end

I did another function like this, but I'm not sure how it is supossed to work with a triple conditional

function k1CheckCB(t)

if (t.k1 == 0.5 || t.k1 == 0.7 || t.k1 == 1.0)
    tableData = uit.Data;
    tableData{t.k1} = t.PreviousData;
    uit.Data = tableData;                             
    warning('Extent values are only 0.5, 0.7 and 1.0') 
end

end

Why not a drop down selection of three values?

[DulceEien]

could I use categorical?

% Drop down

extent = uicontrol('style','popup','string',{'0.5';'0.8';'1.0'});

t.k1 = extent;

like this I don't know how to assign values

[Yongjian Feng]

A simple way is to only modify your callback function to something like this:

function k1CheckCB(hObj, t)
    if ~ismember(t.NewData, [0.5 0.7 1.0])
        % no good.
        warning('Exten must be 0.5, 0.7, or 1.0');
        % reset
        data = hObj.Data;
        data(t.Indices(1), t.Indices(2)) = t.PreviousData;
        hObj.Data = data;
    end
end

thank you for your help

sorry to ask again if I look only in the third column is the Previous Data correct? (I got an error in the index array)

    if (t.Indices(3) == 3 && ... 
        ~ismember(t.NewData, [0.5 0.7 1.0]))
        % no good.
        warning('Exten must be 0.5, 0.7, or 1.0');
        % reset
        data = hObject.Data;
        data{t.Indices(1), t.Indices(2), t.Indices(3)} = t.PreviousData;
        hObject.Data = data;
    end

Oh, k1 is the 3rd column, right? Then you are looking at t.Indices(2) = 3. If you only want to check the k1 column and don't need to worry about the other columns:

function k1CheckCB(hObj, t)
    if t.Indices(2) == 3 % only care about the k1 column
        if ~ismember(t.NewData, [0.5 0.7 1.0])
            % no good.
            warning('Exten must be 0.5, 0.7, or 1.0');
            % reset
            data = hObj.Data;
            data(t.Indices(1), t.Indices(2)) = t.PreviousData;
            hObj.Data = data;
        end
    end
end

I understand, it is because I wanted to limit only to those values for that k1 column (values either 0.5, 0.7 or 1), but I saw that ~ismember for a row values, before as you mentioned I wanted to assign a drop down bottom but I got also a mistake

something like this:

extent = categorical(t.k1,{'0.5','0.7','1.0'});
t.k1 = extent;

@Yongjian Feng thank you so much again, it is working
