Automatic Outline

SpreadJS provides the option to automatically add the row and column outlines to cell ranges containing formulas. You can access the "Auto Outline" option in Data > Group ribbon button.




If outlines already exist in a worksheet, then a confirmation dialog pops up.




If selected "OK", all the existing outlines are removed and new outlines are created according to the current formulas.

Behavior of Automatic Outlines

You can observe the following behavior while applying automatic outlines.

Behavior

Example

The outline direction follows the formula cell position.
