Status

Every data cell in a column has both a value and a status. If the status is OK, you see only the value; if the status is not OK, the value will be copied from the previous cell, but the status will be set appropriately, if the non ok cell is the first one in the row, then the value will be undefined. Categories of bad status include Cut, Blank, Break, Missing, and Error. Transforms allow you to change statuses as well as values.
