In the application that I'm working on I noticed that the placeholder node in empty tables is overwriting the table headers, which looks a bit messy. It's a minor issue, because it only shows up if you alter the min height of the TableView, which we probably shouldn't be doing in our app. But in any case, I think the TableView component could be modified to handle this case more cleanly. Here is a test case to reproduce the issue - run it and try moving the slider up and down while the table has data in it, all is good. Now click the 'Clear' button (so the table displays "There is no data" as a placeholder) and move the slider up towards the top of the table. At the point where there isn't enough room to show the "There is no data" label, it begins to overlap the table headers. In my view, it should stop moving upwards once it reaches the top of the table content area.

Comment out the line "table.setMinHeight(10);" to see that the behaviour is fine in the default case.
