/**
* Accessible interface for AbstractTableView.
* This accessibility interface only exposes what is visible on the screen because the data scale of underlying AbstractTableView is uncontrollable.
* Its direct-child layout matches QAccessibleTable with horizontal and vertical
* headers: a hidden corner, column headers, then a hidden row header followed by
* each row's data cells. Row-header names use the first raw data column, like a
* QTableView model whose vertical headerData contains debugger addresses.
* Like Qt's item-view adapter, virtual children retain the widget and model
* identity and re-query this adapter instead of retaining its address.
