Vertical headers in JTable?

Question

Is there a way to rotate 90º the column headers of a JTable?

Answer 1

Check out Darryl's Vertical Table Header Cell Renderer.

Answer 2

This is little tricky. At first, you need to cast JTable headers to JLabels. It's just like

 ((JLabel)table.getTableHeader()

Then rotate JLabels. It's already answered here on StackOverflow
