Frozen pane configuration for a worksheet view.
Freezing divides a sheet into two or four regions, each called a pane. Two panes can be divided horizontally or vertically, four panes divides a sheet into quadrants. All but one of the panes is frozen (rows and columns are locked in place), and the panes' rows and columns remain visible while you scroll. The final pane scrolls as usual.
Frozen panes (aka freeze panes) are most commonly used to freeze a table's header rows/columns in place.
