11.3. Table rows: the tr element

Enclose each row of your table in a tr element. Here is the content model:

element tr
{ align.attrib?,
  valign.attrib?,
  Common.attrib,
  (th | td)+
}

align.attrib?, valign.attrib?: The align and valign attributes control the default horizontal and vertical positioning of the cells in the row; they are defined in Section 11.1, “Specifying table column properties”.
Common.attrib: The common attributes are discussed in Section 15.3, “The common attributes: Common.attrib”.
(th | td)+: Enclose each ordinary cell of the row in a td element. If the cell is a row heading, enclose it in a th element. See Section 11.4, “Table cells: the td and th elements”.
