如何在JTable中隐藏网格线

我试图隐藏JTable的网格线但没有结果。 即使尝试更改网格线的颜色也不起作用。 这是我的代码:

// build the table tableView = new JTable(ttm); //Specifify the selection Listener and model listSelectionModel = tableView.getSelectionModel(); listSelectionModel.addListSelectionListener(new SharedListSelectionHandler(tableView)); tableView.setSelectionModel(listSelectionModel); //Add a mouse listener to our table and implement double click event tableView.addMouseListener(new MouseAdapter(){ public void mouseClicked(MouseEvent e){ //If double click in a message show the Message Details window if (e.getClickCount() == 2){ showMessageDetail(); } } } ); // set my own renderer CustomCellRenderer mtr = new CustomCellRenderer(); tableView.setDefaultRenderer(Object.class, mtr); // table properties tableView.setGridColor(Color.black); tableView.setShowGrid(false); //tableView.setShowVerticalLines(false); //tableView.setShowHorizontalLines(false); tableView.setSelectionMode(ListSelectionModel.SINGLE_SELECTION); //hide header tableView.setTableHeader(null); // hide the id column String columName = tableView.getColumnName(TableModel.COLUMN_ID); tableView.getColumn(columName).setMaxWidth(0); tableView.getColumn(columName).setMinWidth(0); tableView.getColumn(columName).setWidth(0); //load the messages in the table loadMessages(); //adjust column width tableView = autoResizeColWidth(tableView, ttm); public class CustomCellRenderer extends JPanel implements TableCellRenderer { /** * First gradient color */ private static final Color COLOR_1 = new Color(255, 255, 255, 200); /** * Second gradient color */ private static final Color COLOR_2 = new Color(255, 0, 255, 200); /** * Controls gradient direction */ private static final float SIDE = 50; private GradientPaint gradientPaint = new GradientPaint(0, 0, COLOR_1, SIDE, SIDE, COLOR_2, true); private JLabel label = new JLabel(); public CustomCellRenderer() { setOpaque(true); setLayout(new BorderLayout()); add(label, BorderLayout.CENTER); label.setHorizontalAlignment(SwingConstants.CENTER); } public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) { label.setText(value.toString()); return this; } @Override protected void paintComponent(Graphics g) { super.paintComponent(g); Graphics2D g2 = (Graphics2D) g; g2.setPaint(gradientPaint); g2.fillRect(0, 0, getWidth(), getHeight()); } } 

始终绘制白色网格线。 我被困在这里……

我是否必须实现自定义视口才能摆脱这种情况?

先谢谢你,Alex

你必须设置两件事

  • 禁用网格显示
  • 零行/列小区间距

在代码中:

 table.setShowGrid(false); table.setIntercellSpacing(new Dimension(0, 0)); 

或者使用JXTable(来自SwingX项目 )为您完成:

 xTable.setShowGrid(false, false); 

只是jTable1.setShowHorizo​​ntalLines(false); 或jTable1.setShowVerticalLines(false); 或者您可以使用2选项

 jTable1.setShowHorizontalLines(false); jTable1.setShowVerticalLines(false);
