splitter
If you need to scroll to view all data of an  Application Studio report, you may not see column and row headings. A splitter
		is a horizontal or vertical line that freezes the position of the cells above it or to the
		left. By placing splitters to the right of the row headings and below the column headings,
		you can see the headings while scrolling. You can insert three horizontal and three vertical
		splitters in one report.
