JTable标头对齐

我想在我的JTable-derrived类的标题中设置标签的垂直对齐方式。

我知道setVerticalAlignment(SwingConstants.BOTTOM);

我的标题比字体高得多，我想把文字放在垂直中心的下方 。

如何在不覆盖paint()情况下执行此操作？

谢谢

Answer 1

其中一种方法是设置Renderer ，默认情况下TableHeader返回JLabel

  final TableCellRenderer tcrOs = myTable.getTableHeader().getDefaultRenderer(); myTable.getTableHeader().setDefaultRenderer(new TableCellRenderer() { @Override public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) { JLabel lbl = (JLabel) tcrOs.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column); lbl.setForeground(AppVariables.textColor); lbl.setBorder(BorderFactory.createCompoundBorder(lbl.getBorder(), BorderFactory.createEmptyBorder(0, 5, 0, 0))); lbl.setHorizontalAlignment(SwingConstants.LEFT); if (isSelected) { lbl.setForeground(Color.red); lbl.setBackground(Color.lightGray); } else { lbl.setForeground(Color.blue); lbl.setBackground(Color.black); } return lbl; } }); 

Answer 2

 JTableHeader header = table.getTableHeader(); TableCellRenderer renderer = header.getDefaultRenderer(); renderer.setVerticalAlignment(SwingConstants.BOTTOM);
