Splitting a Spreadsheet View into Two Panes
Open Plan allows you to split the view into two panes in order to “freeze” the columns displayed in the left pane.
No matter how far you scroll the right-hand pane horizontally, the information in the left-hand pane remains the same.
You can still horizontally scroll the left-hand pane if you wish to change the information that is displayed.
At the left edge of the horizontal scrollbar is the splitter control that you can use to drag the splitter bar to the desired position. The splitter bar marks the boundary between the two panes.
