VScrollTable VScrollTable is a FlowPanel having two widgets in it: * TableHead component * ScrollPanel TableHead contains table's header and widgets + logic for resizing, reordering and hiding columns. ScrollPanel contains VScrollTableBody object which handles content. To save some bandwidth and to improve clients responsiveness with loads of data, in VScrollTableBody all rows are not necessary rendered. There are "spacers" in VScrollTableBody to use the exact same space as non-rendered rows would use. This way we can use seamlessly traditional scrollbars and scrolling to fetch more rows instead of "paging". In VScrollTable we listen to scroll events. On horizontal scrolling we also update TableHeads scroll position which has its scrollbars hidden. On vertical scroll events we will check if we are reaching the end of area where we have rows rendered and TODO implement unregistering for child components in Cells

    Specified by:
    
    getSubPartElement in interface SubPartAware
    
    Parameters:
    
    subPart - The identifier for the element inside the component
    
    Returns:
    
    The element identified by subPart or null if the element could not be found.
  - getSubPartName
```
public String getSubPartName(com.google.gwt.user.client.Element subElement)
```
    Description copied from interface: SubPartAware
    
    Provides an identifier that identifies the element within the component. The subElement is a part of the component and must never be null.
    Note! getSubPartElement(getSubPartName(element)) == element is not always true. A component can choose to provide a more generic identifier for any given element if the results of all interactions with subElement are the same as interactions with the element identified by the return value. For example a button can return an identifier for the root element even though a DIV inside the button was passed as subElement because interactions with the DIV and the root button element produce the same result.
    
    Specified by:
    
    getSubPartName in interface SubPartAware
    
    Parameters:
    
    subElement - The element the identifier string should uniquely identify
    
    Returns:
    
    An identifier that uniquely identifies subElement or null if no identifier could be provided.
