The status of this row entry. Before add a row into table, it should be created first. Set Valid(1) to a row will create this row. To delete a row from this table, set this object for the row to invalid(2). Row sets for new rows with a row status set to invalid(2) return a BAD VALUE error. This object will always read as valid(1). If no more rows can be added to the end of the table, then a row set to create a new row will return BAD VALUE. When rows are deleted from this table, the indexes of the other rows do not change. In other words, this table can be 'sparse' or have 'holes'. Deleted entries can be re-created using a row set with a row status of valid(1).
