public interface ListColumnAction<I,V> extends Action, DynamicActionAttributes
Action that inserts a new column into a table listing. The action is used multiple times while generating the table. The first use is creating a column definition. This uses the id, title, value type, properties, sortable and filterable flags, formatter, etc. Then, for each row in the table, the getValue(DbControl, Object) is used to get the actual value that should be displayed in the table. If a formatter has been defined, it is used to format the value, otherwise the Object.toString() method is used.
