    Interface Group

    A group of rows or columns.

    interface Group {
        collapsed: boolean;
        end: number;
        level: number;
        start: number;
        summary: number | null;
    }
    Index
    collapsed: boolean

    Whether the details are collapsed: every one of them is hidden, whoever hid them.

    Read from the hidden details, as Excel reads it. A group whose summary is itself hidden, inside a collapsed outer group, reads collapsed only when it was collapsed before the outer one; expanding the outer group leaves such a group collapsed and opens the rest.

    end: number

    The last detail row or column, inclusive.

    level: number

    The level, from 1; level 1 is the outermost.

    start: number

    The first detail row or column.

    summary: number | null

    The summary row or column, or null when the group runs to the edge of the sheet on the summary side.
