Module outline 

Outline groups (Data ▸ Group) of a sheet’s rows or columns: the runs of lines at or above each outline level, as the grid draws them (brackets, − / + buttons, level buttons) and the Show / Hide Detail commands act on them. Summary rows sit below their detail and summary columns right of it, or above / left of it when the sheet’s outline settings say so (Sheet::summary_below, Sheet::summary_right).

Structs

OutlineGroup

One group: lines start..=end at outline level level or deeper, with its summary line just after end, or just before start when summary_before is set.

Constants

MAX_LEVEL

The deepest outline level XLSX allows.

Functions

Every group, with its summary line after the detail; see groups_with.

Every group, ordered by where it ends (inner groups before the group around them), with its summary line before the detail when summary_before is set.

max_level

The deepest outline level used by these lines (0 = no outline).

summary_before

Whether the sheet’s summary rows (rows) or summary columns sit before their detail.
