Use this window to view, enter, change, and delete the definition for a data column. A data column is used for retrieving data from various data sources. This window is reached via the New Column operation in Column Template. If the data column already exists, you can reach this window via the View Column operation in the same window. You can select several columns if they are of the same type. For the description of each tab in the window, follow the appropriate link: General, Selection, and Layout.
