Split-Wks
In Origin8.5.1, worksheets and matrixsheets can be split into panels using Dividers. You can scroll within each individual split panel while rows or columns in other panels remain visible.
You can split worksheet/matrixsheet from Origin's menu or by dragging the Divider.
You can also remove the split of the worksheet/matrixsheet from Origin's menu or by dragging the Divider.
Note that Split or Remove Split can't be done for matrixsheet in Image Mode.
