Properties
id?
optionalid:string
Optional stable identity of this row. It lets the table keep the row's element (and therefore its expand/collapse state) when new data objects describing the same rows are assigned to the table, instead of recreating every row. It is not a cell value and does not create a column.
Ids must be unique across the whole table. If the same id appears more than once among sibling rows, the first one keeps the id-based identity, the others fall back to object identity, and the table logs a warning.
Rows without an id are identified by object reference, as before.
