    How to remove rich:dataTable header background

    The rich:dataTable header has a gradient by default. To remove it, add the following in your css file:

    .rich-table, .rich-table-header, .rich-table-header-continue,
      .rich-table-footer, .rich-subtable-footer {
         background-image:none;
         background-color:transparent;
    }     
    

     

    If you just trying to apply bg color you also should not redefine bg image with 'none';
