Rendering a cell in JTable

Posted: Jan 31, 2003 2:47 AM

I have a JTable which is populated with rows from the database.
I want to change the background colour of the first row in the table while the other rows should be of some other colour.
Can anyone send a sample code to do this..
I tried with using the cell renderer , however it applies to all the rows in a particular column and does not limit to a single cell.

public class LabelRenderer extends JLabel implements TableCellRenderer{


public Component getTableCellRendererComponent( JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) {

if ( row == 0 )
    super.setBackground( Color.green );
else
    super.setBackground( Color.blue ); // if you really take this colors ... be damned :-)

}

}

Hope this helps,
Rommie.

And if you want to limit it to a single cell, just add an if for the column number, too.
