TableViewBox

A scrolling grid over a row source: it asks for the rows in view, so a massive or infinite collection draws without ever being held.

Details

• CollectionTable and TableView lower to it. The source is held: the page registers it with the kernel and asks for rows by range, so only the expression travels.
• ImageSize fixes the viewport (a fixed height by default), so the page never reflows as rows load. Scrollbars scrolls (the default); Pagination -> True gives pages. ScrollPosition and MaxItems pin a first page, which is all a static environment draws: those rows, then a Skeleton row for the rest.
• TableViewBoxHeaders are the column headings, known before any row is.

Wolfram's TableViewBox takes a list of rows of boxes; this one takes a held row source, so it is ours.
