A DESCRIPTION OF THE PROBLEM :
The documentation for JScrollPane.setColumnHeader() contains a sentence that reads:

"Most applications will find it more convenient to use setRowHeaderView to add a row header component and its viewport to the scrollpane."

This looks like a copy and paste error, since the user would clearly not find it more convenient to add a row header when he wishes to add a column header.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Most applications will find it more convenient to use setColumnHeaderView to add a column header component and its viewport to the scrollpane.
ACTUAL -
Most applications will find it more convenient to use setRowHeaderView to add a row header component and its viewport to the scrollpane.
