Hello!

For a Java project, I need to rename the JTable columns on the fly. I wrote a small test code, where the change of the column names becomes visible only when one clicks on the column name.

Can you tell what to do so that the column name changes whenever the first row content is changed?

Thank you for your support!

You need a TableModelListener to do that

I am using a TableModelListener now, but still have problems, as you can see when executing the attached code. Again, the column name change is visualized when clicking on any column name, but not before.

After the loop, try calling

table.getTableHeader().repaint();

Open in new window
