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

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
