-/**
- * 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
