如何在JTable中隐藏网格线

Question

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());
    }
    }

总是绘制白色网格线。我被困在这里。。。

我必须实现一个自定义Viewport才能摆脱这种情况吗？

提前感谢，Alex

Answer 1

您必须设置两个

• 禁用网格显示
• 零行/列单元间间距

代码中：

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

或者使用JXTable（来自SwingX项目），它为您做这件事：

xTable.setShowGrid(false, false);

Answer 2

仅jTable1.setShowHorizontalLines（false）；或jTable1.setShowVerticalLines（false）；或者你可以使用2选项

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