JFrame JTable column names not showing and scroll bar doesn't show

I'm trying to add a table to my program that has the column names at the top and a scroll bar down the side. For some odd reason everything works, but the column names don't show nor does the scroll bar.

Here's my code, if you need a running program let me know, but you should be able to just add this to an empty JFrame:

String[] columns = {"Sport", "Location", "Date", "Result"};
    String[][] data = {{"Football", "AQA Highschool", "12.11.13", "5 - 0"},
            {"Tennis", "Wembley", "26.11.14.", "TBC"}};

listTable = new JTable(data, columns);
            listTable.setPreferredScrollableViewportSize(new Dimension(450, 750));
            listTable.setFillsViewportHeight(false);
            listTable.setBounds(25, 100, 450, 640);
            JScrollPane scroll = new JScrollPane(listTable);
            guestFixturesPanel.add(listTable);

First of all you're not adding the scroll pane but the table directly to guestFixturesPanel:

guestFixturesPanel.add(listTable);

Second, you must avoid the use of setBounds() method and use a suitable LayoutManager instead. Take a look to A visual guide to Layout Managers. You might also consider third party options suggested here. As @AndrewThompson always says:

Java GUIs might have to work on a number of platforms, on different screen resolutions & using different PLAFs. As such they are not conducive to exact placement of components. To organize the components for a robust GUI, instead use layout managers, or combinations of them, along with layout padding & borders for white space.

guestFixturesPanel.add(listTable);

is wrong ! you must add the scroll like this:

guestFixturesPanel.add(scroll);
