UWL not Responding in Custom Theme changes

Hi All,

I have tried to change the color of the UWL table and of the background color i.e. surrounding the table via creating a custom Theme and
changing all the following parameters:

• Complex Elements > Tables > Standard Table
  Cells >Standard Table Header > Background Color of Header > #FFFFFF\
• Simple Elements > Labels and Fields >Read-Only Input Fields>Background Color of Read-only Input Field > #FFFFFF
• Portal Body > Background Color of Portal Pages > #FFFFFF
• Complex Elements> Tabstrip>Selected Tab>#FFFFFF
• Complex Elements> Tabstrip>TabPage>Color of Top Line of Tab Page>#FFFFFF
• Complex Elements> Tabstrip>Tab Page>Background Color of Tab Page Content>#FFFFFF
• Complex Elements>iView Trays>Tray Header>Background Color of Header>#FFFFFF
• Simple Elements > Labels and Fields>Disabled Input Fields>#FFFFFF

Unfortunately the UWL table color and the background color are not changing. The only visible change via the custom theme is the Background
Color of Portal Pages.

Do you have to recommend any other way of changing the color of UWL table and its background color?

Any help is much appreciated.

Thank you in advance.

Kind Regards,

Michael
