problem to change color after dropdown menu

hi, i use dropdown menu in app designer to change value in table .
C is matrix with rows and columns to be highlighted in yellow
but the previous colors remain

function DateSearchDropDown_5Clicked(app, event)
               item = event.InteractionInformation.Item;
             if ~isempty(item)
                  [app.UITable_CorrelationTab.Data,c]=Table_Correlazione_Struct(app.Eq,app.Preset,app.DateSearchDropDown_5.Value);
                  s = uistyle('BackgroundColor','yellow');
                   addStyle(app.UITable_CorrelationTab,s,'cell',c);
            end                         
        end

     
I think you have to restore the original colors and then color the new matrix   
How can do it?

If that's the only uistyle you use on the table, then calling removeStyle to remove all uistyles before adding the new one should work:

function DateSearchDropDown_5Clicked(app, event)
    removeStyle(app.UITable_CorrelationTab);
    item = event.InteractionInformation.Item;
    if ~isempty(item)
        [app.UITable_CorrelationTab.Data,c]=Table_Correlazione_Struct(app.Eq,app.Preset,app.DateSearchDropDown_5.Value);
        s = uistyle('BackgroundColor','yellow');
        addStyle(app.UITable_CorrelationTab,s,'cell',c);
    end
end
