AutoOutline

If the selected cell range contains formulas or references, Collabora Office 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.
