How align data columns in a JTable

[Flavio Nobili]

Hi to all,
How can I change the alignment of a data column in a JTable?

Regards,
Fl�vio.

Taking advantage of the fact that DefaultTableCellRenderer extends JLabel.

One approach is creating as many renderers as alignments you need. For instance the renderer providing right one:

class RightTableCellRenderer extends DefaultTableCellRenderer { 
  protected  RightTableCellRenderer() {
    setHorizontalAlignment(JLabel.RIGHT);  } 
  
} 

Then you could assign such instance to any TableColumn needing right alignment: aTableColumn.setRenderer(aRightTableCellRenderer)

Thanks Jose for your help.
It worked fine.

By the way there is no need of subclassing. Instantiate a DefaultTableCellRenderer, set its alignment and assign it to several TableColumns.
