3/**
4 * Definition for tables. The general idea is to extract out all of the
5 * essential bits, and then reconstruct it later.
6 *
7 * This is a bit confusing, because the DTDs and the W3C
8 * validators seem to disagree on the appropriate definition. The
9 * DTD claims:
10 *
11 * (CAPTION?, (COL*|COLGROUP*), THEAD?, TFOOT?, TBODY+)
12 *
13 * But actually, the HTML4 spec then has this to say:
14 *
15 * The TBODY start tag is always required except when the table
16 * contains only one table body and no table head or foot sections.
17 * The TBODY end tag may always be safely omitted.
18 *
19 * So the DTD is kind of wrong. The validator is, unfortunately, kind
20 * of on crack.
21 *
22 * The definition changed again in XHTML1.1; and in my opinion, this
23 * formulation makes the most sense.
24 *
25 * caption?, ( col* | colgroup* ), (( thead?, tfoot?, tbody+ ) | ( tr+ ))
26 *
27 * Essentially, we have two modes: thead/tfoot/tbody mode, and tr mode.
28 * If we encounter a thead, tfoot or tbody, we are placed in the former
29 * mode, and we *must* wrap any stray tr segments with a tbody. But if
30 * we don't run into any of them, just have tr tags is OK.
