Yes, that's the correct way to do it. The table pane header is generated
early in the construction process, so is difficult to change later. By
providing to the constructor the function to instantiate your custom pane
header, you allow the pane header to be constructed initially the correct
way. (There are some components of Table, and thus TreeVirtual, that simply
can't be changed later. I don't recall offhand whether the pane header is
one of those, but this is certainly the easiest way to do it in any case.)
