AutoOutline If the selected cell range contains formulas or references, $[officename] automatically outlines the selection.

For example, consider the following table: January February March 1st Quarter April May June 2nd Quarter 100 120 130 350 100 100 200 400 The cells for the 1st and 2nd quarters each contain a sum formula for the three cells to their left. If you apply the AutoOutline command, the table is grouped into two quarters. To remove the outline, select the table, and then choose Data - Group and Outline - Remove.
