Details

• Held: it is the handle a TableViewBox carries, and the kernel it is registered with answers rows(range). Rows are numbered by the index At(collection, #) reproduces, as bigints, so SymmetricGroup(25) reaches its last row.
• Columns are expressions over the row _ (a bare head Descents means Descents(_)), Filter a predicate over it, SortBy a column. A filter makes the count a lower bound until the scan covers the source; sorting an infinite source declines.
• A collection with no stable order (a finite Set) declines; random access uses the collection's At when it has one, and otherwise a prefix walk.
