void Worksheet::freezePanes (
Set panes and mark them as frozen. One can use this method to mark certain regions in the worksheet so that they are "frozen" in the sense that when scrolling through the worksheet these regions are not affected by the scrolling and remain where they are on the screen. This is the same functionality as provided by Microsoft Excel through the -> menu command.
array $panes - This is the only parameter received and is composed of the following: 0 => Vertical split position, 1 => Horizontal split position 2 => Top row visible 3 => Leftmost column visible 4 => Active pane

$worksheet =& $workbook->addWorksheet("Some Worksheet");

/* Freeze the first six rows and start the scrollable region at row nine: */
$worksheet->freezePanes(array(6, 0, 9, 0));
