You just need to call the getTableHeader()method. Then on the object of class JTableHeaderuse the setFont(/*font*/)method to set new font.
您只需要调用该getTableHeader()方法。然后在类的对象上JTableHeader使用该setFont(/*font*/)方法设置新字体。
table.getTableHeader().setFont( new Font( "Arial" , Font.BOLD, 15 ));

To keep the same Font family and just change the size you can use:
要保持相同的字体系列并更改大小，您可以使用：
JTableHeader header = table.getTableHeader();
header.setFont( header.getFont().deriveFont(16) );

not sure from your question, then I post both options
不确定你的问题，然后我发布了两个选项
1) set Font for JTable myTable.setFont(new Font("Arial", Font.PLAIN, 10))
1) 为 JTable 设置字体 myTable.setFont(new Font("Arial", Font.PLAIN, 10))
2) set Font for TableHeader
2) 为 TableHeader 设置字体
final TableCellRenderer tcrOs = table.getTableHeader().getDefaultRenderer();
table.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.setBorder(BorderFactory.createCompoundBorder(lbl.getBorder(), BorderFactory.createEmptyBorder(0, 5, 0, 0)));
lbl.setHorizontalAlignment(SwingConstants.LEFT);
if (isSelected) {
lbl.setForeground(Color.red);
lbl.setFont(new Font("Arial", Font.BOLD, 12));
} else {
lbl.setForeground(Color.darkGray);
lbl.setFont(new Font("Arial", Font.PLAIN, 10));
}
return lbl;
}
});
