问题 I have a use case which I would assume is pretty standard, however I haven't been able to find an example on exactly how to do this, or if it's possible. Let's assume I have the following TableView First Name Last Name Street NewRecord Tom Smith Main St. Yes Mike Smith First St. No In this case, the grid should have the first three cells editable since the record is new, however when the record is not new then the Last Name cell should be disabled. I tried this in the CellFactory and

问题 How would I go about creating a JTable in Swing that allows the user to toggle columns with a simple dropdown meun, like in Windows Explorer folders? My table has 12 columns, and the screen cannot fit all the information on the screen at once. Since the user may not need to see many of these columns, this seems like the best option. I assume it would use a JPopupMenu that appears when the user right-clicks the table header, with a JCheckBoxMenuItem for each column. Here's a screenshot of

问题 I am looking to create a custom TableColumn which is a CheckBox control which represents if the row is selected or not. We don't want to use the standard SHIFT or CONTROL + CLICK to handle this as users tend to click inadvertantly and lose their selection. What I would like to do is the following: In this case the column should not be part of the underlying data model, and simply represent what is selected or not. It shouldn't be dependent on the data model in any way. If the user selects the
