MS EXCEL - Freeze Pane
Used to keep an area of a worksheet visible while you scroll to another area of the worksheet, you can lock specific rows or columns in one area by freezing or splitting panes.
You may want to see certain rows or columns all the time in your worksheet, especially header cells.
By freezing rows or columns in place, you’ll be able to scroll through your content while continuing to view the frozen cells.
1. Select the row below the row(s) you want to freeze.
2. Click the View tab on the Ribbon.
3. Select the Freeze Panes command, then choose Freeze Panes from the drop-down menu.
The rows will be frozen in place, as indicated by the gray line. You can scroll down the worksheet while continuing to view the frozen rows at the top. Repeat the same for column freezing.
To unfreeze rows or columns, click the Freeze Panes command, then select Unfreeze Panes from the drop-down menu.
