問題文
An author takes one column out of a dataset table using Edit Definition, then takes a second column out from inside the transform editor. How does the documentation describe the two removals afterwards?
選択肢
- The transform editor leaves no trace of the first one, while a step for the second one waits in the Preparation Script to be dropped.
- Neither of them can be undone from the dataset editor, though a dataset filter already written on the column keeps working in both cases.
- The Preparation Script holds a step for each of them, though dropping either step is what returns the column to its dataset table.
- The first one leaves the dataset table as it stands, whereas the second one takes the column out of the table that lies underneath for good.
