You don't.

You can set <td width="20" style="overflow:hidden"> or use a serverside language to add spaces to the line yourself.

Here's a Javascript function that will add hard line breaks to any string:

<script type="text/javascript">
  function addBreaks(str,len) {
    var result="";
    while (str.length > len) {
      result += str.substring(0,len) + "<br>";
      str = str.substring(len);
    }
    result += str;
    return result;
  }
</script>

You can replace the break with a space.

javascript:(function() { var D = document; F(D.body); function F(n) { var u, r, c, x; if (n.nodeType == 3) { u = n.data.search(/\S{45}/); if (u >= 0) { r = n.splitText(u + 45); n.parentNode.insertBefore(D.createElement('wbr'), r); } } else if ((n.tagName != 'STYLE') && (n.tagName != 'SCRIPT')) { for (c = 0; x = n.childNodes[c]; ++c) { F(x); } } } D.body.innerHTML += ' '; })();

That's a nice "url" you can type in the address bar of the browser on any page you want (copy/pase is easier though, saving it as a bookmark is even easier).
It processes the complete document and adds <wbr> inside words that are longer than 45 chars.
You could call that method when your page loads, but it's rather slow to execute... it's better to only process the required elements.

And nobody said anything about the non-standard IE-only "wordwrap: break-word":  http://www.blooberry.com/indexdot/css/properties/text/wordwrap.htm
