推荐答案

一种方法是使用UIManager并将默认的Font替换为所需的

One way would be to use the UIManager and replace the default Font with the one you want

Font font = UIManager.getFont("TableHeader.font");
font = font.deriveFont(48f);
UIManager.put("TableHeader.font", font);

将替换系统中所有表使用的字体

Which will replace the font used by all the tables in the system

另一种方法是为要更改的列提供自定义TableCellRenderer，这虽然需要做更多的工作，但是可以提供更大的灵活性，因为您可以决定要在何处应用它们.您可以将其包装在自己的自定义JTableHeader中，但我只是提供一些基本想法.

Another way is to provide a custom TableCellRenderer for the columns you want to change, it's a little more work, but provides more flexibility as you can decide where you want to apply them. You could wrap this inside your own custom JTableHeader, but I'm just providing some basic ideas.

public class HeaderRenderer implements UIResource, TableCellRenderer {

    private TableCellRenderer original;

    public HeaderRenderer(TableCellRenderer original) {
        this.original = original;
    }

    @Override
    public Component getTableCellRendererComponent(JTable table,
                                                                                                 Object value, boolean isSelected, boolean hasFocus, int row,
                                                                                                 int column) {
        Component comp = original.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
        comp.setFont(comp.getFont().deriveFont(Font.BOLD));
        return comp;
    }

}

哪个安装方式类似于...

Which is installed using something like...

HeaderRenderer header = new HeaderRenderer(table.getTableHeader().getDefaultRenderer());
TableColumnModel columnModel = table.getColumnModel();
columnModel.getColumn(0).setHeaderRenderer(header);

并产生类似...

总而言之，您将不得不动手并编写一些代码，表单编辑器将无法为您做任何事情

The long and short of it is, you're going to have to get your hands dirty and write some code, the form editor won't do everything for you
