一种方法是设置
Renderer，
TableHeader默认情况下返回
JLabel，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; } });
