XHTML Tutorial - Table Row "tr" Tag/Element
(Continued from previous topic...)
What Is a "tr" Tag/Element?
A "tr" element is a special element that can only be used as a
sub-element of a "table" element. A "tr" element defines a row in a table.
Here are basic rules about "tr" elements:
- "tr" elements are special elements only valid inside "table" elements.
- "tr" elements can not have empty contents.
- "tr" elements can not have text contents.
- A "tr" element can only have "td" or "th" as sub-elements.
- A "tr" element will be displayed as a new row in the table.
Some invalid example of "tr" elements:
<!-- Invalid - "tr" is not a block element -->
<body><tr><td>one</td></tr></body>
<!-- Invalid - "tr" is not an inline element -->
<p><tr><td>one</td><td>two</td></tr></p>
<!-- Invalid - "tr" does not allow text content -->
<table><tr>Row 1:<td>one</td><td>two</td></tr></table>
