JTable头对齐

Question

我想在我的JTable-derrived类的头中设置标签的垂直对齐方式。

我知道setVerticalAlignment(SwingConstants.BOTTOM);

我的头比字体高得多，我想文将略低于垂直中心。

我该怎么做，而不是重写paint()？

Answer 1

的方法之一是默认返回JLabel设置Renderer，TableHeader，例如

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);
