Drawing number tables

Hi:

I need to draw a table which will be full of numbers. I also need to draw
lines over the numbers (for example, draw a horizontal line from the first
column to the last one, over all the numbers of the first row, etc).

You can see an example of what I want here:

I think JTable would be suitable for the work, but can't realize how to draw
the lines over a JTable's row (with Java2D, for example), so I hope you can
give me some solution or way to get the table done.

Thanks!

class MyTable extends JTable {

public void paint(Graphics g) {
super.paint(g);
paintLines(g);
}

protected void paintLines(Graphics g) {
//draw lines here
}
}

Would it not be better to create a TableCellRenderer that does the line
drawing for you rather than extending JTable? Your TableCellRenderer
can use a JLabel to dislay the number. JLabels can render HTML. HTML
has a strike through <strike>word</strike>.

Thats what I would look into first anyway.

hope I helped,
Martin

if you look at his image, you will find there also vertical lines,
Note also that lines must be _inside_of_cell_ to be drawn by renderer.
