preceding (int, tuple, or None, default None) – Specify None for unbounded, 0 to include current row tuple for off-center window
following (int, tuple, or None, default None) – Specify None for unbounded, 0 to include current row tuple for off-center window
group_by (expressions, default None) – Either specify here or with TableExpr.group_by
order_by (expressions, default None) – For analytic functions requiring an ordering, specify here, or let Ibis determine the default ordering (for functions like rank)
