表は TABLE 要素で表します。この要素はブロック要素です。
<table> ...the rest of the table... </table>
TABLE 要素とその子孫要素の文書型定義；
<!ELEMENT TABLE - - (CAPTION?, (COL*|COLGROUP*), THEAD?, TFOOT?, TBODY+)> <!ELEMENT CAPTION - - (%inline;)* -- table caption --> <!ELEMENT THEAD - O (TR)+ -- table header --> <!ELEMENT TFOOT - O (TR)+ -- table footer --> <!ELEMENT TBODY O O (TR)+ -- table body --> <!ELEMENT COLGROUP - O (COL)* -- table column group --> <!ELEMENT COL - O EMPTY -- table column --> <!ELEMENT TR - O (TH|TD)+ -- table row --> <!ELEMENT (TH|TD) - O (%flow;)* -- table header cell, table data cell-->
TABLE 要素は、 CAPTION, CLGROUP, COL, THEAD, TBODY, TFOOT 要素を子供要素に持てます。特に TBODY 要素は必須で、一つ以上持たなければなりませんす。
THEAD, TFOOT, TBODY 要素は TR 要素を一つ以上子供要素に持たなければなりません。
TR 要素は TH 要素と TD 要素を子供要素に持てます。最低でも何れか一つ以上を持たなければなりません。
TABLE 要素と CAPTION 要素を除いた全ての要素が、終了タグ省略可能 (Optinal) です。 TBODY 要素は、 THEAD 要素と TFOOT 要素が現れない表に限り、開始タグも省略可能です。しかし、実際には Netscape Communicator 4.x が終了タグの省略を解釈できないので、 TABLE 要素の終了タグは省略しない方が良いでしょう。

以上が Transitional DTD における TABLE の定義です。
これは Transitional DTD の抜粋なので、廃止予定の非推奨属性が多数含まれています。ボーダーなどの見栄え指定用の属性は全て非推奨です。
TABLE 要素の属性で必須 (#REQUIRED) なものは特に有りません。
