Bolding text in a JTable cell

Hi,
I was wondering if anybody could please tell me how I can BOLD text in a particular cell within a JTable? From what I've read, it is simply a matter of playing around with a CellRenderer, maybe something like:

void setColour (TableColumn t){
  DefaultTableCellRenderer d = new DefaultTableCellRenderer();
  d.setFont(new Font("Courier", Font.ITALIC, 12));
  t.setCellRenderer(d);
 
  //trying to "hard-code"
  Component c = t.getHeaderRenderer().getTableCellRendererComponent(null, t.getHeaderValue(), false, false, 0, 0);
 
  c.setFont(new Font("Courier", Font.ITALIC, 12));
}

However, I can't seem to get a visual response from the JTable i.e. by querying the column/cell in question, I can confirm that the Font attribute of the column/cell/renderer has been updated, but there still isn't a change in the table when I run the Frame containing it.

Any suggestions would be greatly appreciated.
Cheers,
Blair

In the above code you haven't set the property Bold.
Use c.setFont(new Font("Courier", Font.ITALIC + Font.BOLD , 12));

You need to set the font on the renderer.
Or define your own renderer.

((JLabel)t.getHeaderRenderer()).setFont(new Font(("Courier", Font.BOLD, 12));

Yeah, sorry, I initially had tried BOLD in place of ITALICS, but then I tried ITALICS to confirm that I wasn't getting anywhere.

I've tried all your suggestions but I'm still not seeing either BOLDED or ITALICISED text in my JTable. Is there some property of the JTable or the JScrollPane it sits on that could be over-riding the cell-renderer somehow?

kvkamesh,

Please read ee guidlines for proposing answers.
That's exactly what tonus said.

bmarfell,

Yes, I wasn't sure if setting the font on the renderer would work or not.
Sounds like you'll need to use the other option I specified and install your own renderer:

class MyTableCellRenderer extends DefaultTableCellRenderer
{
   public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column)
   {
      COmponent c = super.getTableCellRendererComponent(table, value, isSelected, hasFocus, row, column);
      c.setFont(new Font("Courier", Font.ITALIC+Font.BOLD, 12));
      return c;
   }
}


And then use as follows:

table.getTableHeader().setDefaultRenderer(
   new MyTableCellRenderer());

tonus> c.setFont(new Font("Courier", Font.ITALIC + Font.BOLD , 12));

kvkamesh> d.setFont(new Font("Courier", Font.ITALIC+Font.BOLD, 12));

You tell me the difference.
