    Interface BreakJSON

    A page break as JSON.

    index is the row (or column) the break sits before. min and max are the columns (or rows) it spans; Excel writes the whole sheet, or the print area's extent for a break made inside one.

    interface BreakJSON {
        automatic?: boolean;
        index: number;
        max?: number;
        min?: number;
        pivot?: boolean;
    }
    Index
    automatic?: boolean

    Placed by the print layout, not by the user. Kept, but not one of the sheet's page breaks.

    index: number
    max?: number
    min?: number
    pivot?: boolean

    Placed by a pivot table.
