I want the data above the specified threshold to be colored in the table (in app designer)

d=table2array(app.data);
            d=rmmissing(d);
            [Coeff,P]=corrcoef(d);

            app.UITable5.ColumnName=app.VarNames;
            app.UITable5.Data=Coeff;
            app.UITable5.RowName=app.VarNames; 

            app.UITable6.ColumnName=app.VarNames;
            app.UITable6.Data=P;
            app.UITable6.RowName=app.VarNames;

            nr=size(app.UITable5.Data,1);
            nc=size(app.UITable5.Data,2);
            t=app.TCorrelationEditField.Value;
            for i=1:nr
                for j=1:nc
                    if app.UITable5.Data(i,j)>=t
                        app.UITable5.BackgroundColor(i,j)=[1 0 0];
                    end
                end
            end

which MATLAB version you are using?

app.OutputTable.BackgroundColor; % this will return the uitable background color

Add style to table or tree UI component - MATLAB addStyle - MathWorks Deutschland - if you are using version 2019a (here you can find some example too

Hi @Amir Azadeh Ranjbar,

The functionality regarding adding a background colour to those cells of 'uitable' in App Designer which are above a certain threshold can be achieved in the following way:

• Creating a 'uistyle' object to target the 'BackgroundColor'.
• Iterating through a loop to check if the cell data is within the desired threshold or not.
• If condition is satisfied the using 'addStyle' function to apply the 'uistyle' to the particular cell in the table.

Here is an example:

threshold = 50; 

% Create a style object
style = uistyle('BackgroundColor', 'red');


% Loop through the data and apply coloring
for row = 1:numRows
    for col = 1:numCols
        cellValue = data{row, col};
        if isnumeric(cellValue) && cellValue >= threshold
            addStyle(app.UITable, style, 'cell', [row, col]);
        end
    end
end

The following MathWorks documentations can be referred to know more:

'uistyle': https://www.mathworks.com/help/matlab/ref/uistyle.html

'addStyle': https://www.mathworks.com/help/matlab/ref/matlab.ui.control.table.addstyle.html

Thanks.
