Here's my list:
the columns are not scored
We're going to need an extra row which contains the column scores.

Check this picture out.

I plan to create a new function, row5() to produce this extra row.
So create a new file row5.js and see how far you can get.

function row5() {
  for (var i=5; i<10; i++) {
    var s1="<div id='s";
    var s2="'>0</div>";
    document.write(s1 + i + s2);
  }
}

Use this new function in your index.html and see how you go.
