Which rows are exported

By default an export holds every row that passes the table's filters, on every page, in the current sort. Paging is a screen concern; the file gets the whole result.

The rows option changes that:

await exportXlsx(table, { rows: "selected" })

ExportMenu adds a "Selected rows only" checkbox when rows are selected. A selection column is usually a display column with checkboxes. Display columns have no accessor, so Rowpine leaves them out of the file on its own:

helper.display({ id: "select", cell: ... }) // not exported: no accessor
