UI spec (http://xdesign.us.oracle.com/projects/javaFX/fxcontrols-ue/specifications/table/Table-UESpec-Revised.html) is not implemented completely:

Space Selects the lead item if it is not selected. Deselects the lead item if it is selected
Ctrl-Shift-Home/End Extends selection to the beginning/end of column, if in multi-cell and multi-row selection mode
Ctrl-PageUp/PageDown Moves selection one page left/right in cell or column selection. Scrolls one page left/right in column selection
Shift-PageUp/PageDown Extends selection one page up/down in cell or row selection
Ctrl-Shift-PageUp/PageDown Extends selection one page left/right in cell or column selection

Works incorrectly:
Home/End Moves selection to the beginning/end of row, if in cell and column selection mode (actually moves selection to the first/last row)
Ctrl-Home/End Moves selection to the beginning/end of column, if in cell and row selection mode (actually moves selection to the beginning/end of row)
