How to change JTable header height?

Question

Title explains the question. How can I easily do that?

Answer 1

Font bigFont = new Font("sansserif", Font.PLAIN, 24); // or whatever
myTable.getTableHeader().setFont(bigFont);

This is a simple way to increase the preferredSize of the TableHeader. It will increase the height of the header, but if your column names are too long then they might not fit widthwise.
