How do I move a label to a new line?

Is there a new line command for SWT on windows? If there isn't, what am I doing wrong here?

Here's the code

    public static void main (String [] args) {
    Display display = new Display();
    Shell shell = new TabsTest().createShell(display);
    shell.setSize(350,500);
    shell.open();
    while (!shell.isDisposed()) {
        if (!display.readAndDispatch())
            display.sleep();
    }
}

private Shell createShell(final Display display) {
    final Shell shell = new Shell(display);
    shell.setText("Betting Tracker");

    //Creating grid layout, used to organize the shell
    GridLayout gridLayout = new GridLayout();
    gridLayout.numColumns = 20;
    shell.setLayout(gridLayout);

    //Grid1
    GridData gridData = new GridData(GridData.FILL, GridData.CENTER, true, false);
    gridData.horizontalSpan = 20;

    new Label(shell, SWT.NONE).setText("Bet Type:");
        betType = new Combo(shell, SWT.SINGLE | SWT.BORDER);
        betType.setItems(new String[] {"   ", "NFL", "NBA", "CFB"});
        betType.setLayoutData(gridData);

    //Grid2
    GridData gridData2 = new GridData(GridData.BEGINNING, GridData.CENTER, true, false);
    gridData2.widthHint = 20;   
    gridData2.horizontalSpan = 5;

    new Label(shell, SWT.NONE).setText("Bets Played:");
        numBets = new Text(shell, SWT.NONE);
        numBets.setLayoutData(new GridData(GridData.FILL, GridData.CENTER, true, false));
        numBets.setLayoutData(gridData2);

    new Label(shell, SWT.NONE).setText("    Won:  ");
        betsWon = new Text(shell, SWT.NONE);
        betsWon.setLayoutData(new GridData(GridData.FILL, GridData.CENTER, true, false));
        betsWon.setLayoutData(gridData2);

    new Label(shell, SWT.NONE).setText("    Lost:  ");
        betsWon = new Text(shell, SWT.FILL);
        betsWon.setLayoutData(new GridData(GridData.FILL, GridData.CENTER, true, true));
        betsWon.setLayoutData(gridData2);   

    //Grid3
    GridData gridData3 = new GridData(GridData.CENTER, GridData.CENTER, true, false);
    gridData3.horizontalSpan = 20;

    new Label(shell, SWT.NONE).setText("Todays Lines");
        lines = new List(shell, SWT.MULTI | SWT.BORDER | SWT.V_SCROLL);
        lines.setItems(new String[] { "OKC(+2.5) - MIA(-2.5)", "DAL(+8) - BOS(-8)" });
        int listHeight = lines.getItemHeight() * 12;
        trim = lines.computeTrim(0, 0, 0, listHeight);
        gridData3.heightHint = trim.height;
        lines.setLayoutData(gridData3);

    return shell;
}

}

The problem is where I create a new Label under the //Grid3 comment. That label is sticking to the line above it, rather than coming to a new line. I'm brand new at SWT so I know it's just lack of knowledge on my part. I'll include a picture so you can see the issue.

You can see the label 'Todays Lines:' isn't on it's own line.

Any help would be tremendously appreciated!

You assign more than once the layout data of the Texts, first to new GridData() then gridData2. Once is enough. The reason the new label does not appear on the new line is that the grid has 20 columns as set with gridLayout.numColumns = 20;. gridData2 has horizontalSpan = 5. If you add 3 labels (spanning 1 column as default) and three Texts spanning 5 columns (as per gridData2), the label you want on the new line will appear in the 19th column still on the same row.

I suggest to assign separate GridData instances to the Texts and divide the number of columns to span among them to sum up to 20 (e.g. the last one spans not 5 but 7 columns), this way 'Today lines' will be placed in the next row.
