When event occurs, execute the specified JavaScript.
id = "name"
You can give a text a name, which allows it to be referenced and changed in a script (dynamic HTML).
lang="lang"
Indicates the language of the text within the text.
span=n
Number of columns that will be spanned. The default is 1.
style="style"
Defines the style in which the text will be displayed. This overrides any style elements at an "outer" level, such as from the BODY or the Cascading Style Sheet.
title="title"
You can give a text a title if you want. This provides some additional information about the text. I'm not sure why you would want to do this, but you could.
valign=n
Specifies the vertical alignment of the data within the cells.

BASELINE First line of each element in the cell aligned with a baseline.
BOTTOM Align elements with bottom of cell.
MIDDLE Align to middle.
TOP Align to the top.
width="n"
Width of each column defined by the <COL> tag. Overrides any width specified in the <COLGROUP> tag. 

Width may be a number of pixels, percentage or relative value.

A relative value is a number followed by an asterisk (*). The way this works is the columns are divided up according to the relative values.

Note that relative values are not supported by Internet Explorer,

Examples:

<table border="1" width="80%">
<COLGROUP SPAN=2 ALIGN=RIGHT>
<COLGROUP SPAN=2 ALIGN=left>
   <tr>
      <td>TEST1</td>
      <td>TEST2</td>
      <td>TEST3</td>
      <td>TEST4</td>
   </tr>
</table>
