问题 currently the JTable cell is selected on first click, and on the second one it is edited. Is it possible to directly edit it on the first click? 回答1: In the DefaultCellEditor api there is a method named setClickCountToStart DefaultCellEditor singleclick = new DefaultCellEditor(new JTextField()); singleclick.setClickCountToStart(1); //set the editor as default on every column for (int i = 0; i < table.getColumnCount(); i++) { table.setDefaultEditor(table.getColumnClass(i), singleclick); } 回答2:

问题 I am trying to find out an elegant way to make JTable stop cell editing (cancel it actually) when user closes the main application window. I know something like this can be done using the WindowAdapter but for this to work properly I need a reference to the window.

问题 My question is clear. Is there any way to restore the width of the columns automatically after user has resized them? Every time the button is clicked, I want the column widths to be restored. public class TableTest { public static void main(String[] args) { SwingUtilities.invokeLater(() -> { JFrame frame = new JFrame(""); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setLayout(new BorderLayout()); JTable table = new JTable(new Object[][] { { "something", "something else" } },
