HTML output is lacking borders, alignment

[GoogleCodeExporter]

I've used get_html_string() - but it produces a rather poor table.
It lacks:
1. Borders
2. Alignment settings

I'd also add using a sans-serif font should be very helpful.

This will make the HTML on par with the ASCII output. Currently, it's not 
usable as it looks real bad (at least on my test case).
 The ASCII output looks excellent.
