WHD does not support all HTML coding as we may like it to. It supports 'BBCode' and this is the example of what you can do in notes or FAQs:
Notes can be formatted with HTML or BBCode. URLS and E-mail addresses are formatted automatically as hyperlinks.
Supported HTML tags:
b, i, u, font, ul, ol, li, br, p, a, img, pre
Supported BBCode tags:
[b] ... [/b]
[i] ... [/i]
[u] ... [/u]
[color=red] ... [/color]
[size=20] ... [/size]
[img] ... [/img]
[list][*]Item 1 [*]Item 2 [*] ... [/list]
[code] ... [/code]
[email] ... [/email]
[url] ... [/url]

Peter created a page with some cool tips for BBCode here:

However, I have not been able to find how to get tables to work. Even BBCode for Tables doesn't seem to be accepted. Feature request?
