I sort of have plans for a pronunciation thing, but it would be auto-generated by sound changer rules, and permit manual overrides for irregularity just like the inflection tables. (The feature creep factor is strong with this one, oh yes.)

As Ness said, the table tags are derived directly from their HTML counterparts. The letter "d" as an abbreviation for "data" is typical of the jargon used in the HTML standards. (There's another tag, <dd>, which means definition data, for example.)

To use fancy formatting with table elements, use a colon and type in some CSS properties: [td: color: orange; background: black;] will give you a fancy halloween theme.
