A TableView or TreeTableView that uses a TableView.CONSTRAINED_RESIZE_POLICY and a visible table menu button will have the rightmost portion of the rightmost column in the table obscured by the table menu button. This makes it difficult to put arbitrary nodes into a table column (header). It also affects the nodes used to indicate sort order; if the rightmost column is sorted, the sort indicator is obscured. Here is an example:

To reproduce:
1) Run the above example.
2) Grab the very left edge of the slider and move it as far right as possible.
The slider will go "underneath" the table menu button.
