Changing the font of a certain cell within a JTable

+4
−0

I am trying to change the font type and size in a JTable cell. Ive looked at tons of posts and while most don't produce stack traces, they don't seem to do anything either.

Here is the code I currently have. The result of the code within BorderLayout() is making my table look like a blank white box which would otherwise look like a normal table without the code. Is anyone familar with how to achieve this?

public class YahtzeeCard extends JPanel {
     private JTable topScore = new JTable(10, 7);
         //...other private vars...

     public YahtzeeCard(int width, int height) {
        this.height = height;
	this.width = width;
	
	setPreferredSize(new Dimension(width, height));
	setBorder(BorderFactory.createLineBorder(Color.black));
	setBackground(Color.white);	
	BoardLayout();
}
 
    public void BoardLayout() {
         //...add rows/columns to model, change cell size, etc...
         TableCellRenderer render = topScore.getCellRenderer(0, 0);
         topScore.setDefaultRenderer(TableCellRenderer.class, render); 
         Component c = topScore.prepareRenderer(render, 0, 0);
         c.setFont(new Font("Tahoma", Font.BOLD, 12));
    }
}

It turns out that my table cell renderer I was using wasn't initialized -.-
