      public TableItem(Table parent, int style)
      Constructs a new instance of this class given its parent (which must be a Table) and a style value describing its behavior and appearance. The item is added to the end of the items maintained by its parent.

The class description lists the style constants that are applicable to the class. Style bits are also inherited from superclasses.

      Parameters:
      parent - a composite control which will be the parent of the new instance (cannot be null)
      style - the style of control to construct
      Throws:
      IllegalArgumentException -
      • ERROR_NULL_ARGUMENT - if the parent is null
      SWTException -
