What you want is a custom cell type.  One standard provided custom cell
type is FXComboTableItem, derived from FXTableItem.

Custom items may overload some of the functionality in FXTableItem; for
example, drawContent().  The basic FXTableItem draw() function is split
into drawBackground(), drawPattern(), drawContent() and then drawBorders().

Each of these are overloadable, but my suggestion is to only overload
drawContent().

Next, when the user clicks on the item to edit it, the FXTableItem's
getControlFor() API is called, its purpose is to create a widget to
edit the cell contents.  The standard FXTableItem's implementation
makes a FXTextField, sets the appropriate text justification options,
and fills the contents of the FXTextField with the value of the cell.

The control is placed over the cell by the FXTable.  After the user is
done with editing, the items setFromControl() is called.  The default
implementation grabs the text from the FXTextField and sticks it into
the cell.

The code in FXTable.{h,cpp} for implementing the FXComboTableItem may
be worth looking at to see how to implement a custom item.
