Attribute Values
| Value |
Description |
| pixels |
Length in pixels (like "100px", or just "100"). |
| percent |
Length in percent of entire table (like "20%"). |
| relative_length |
Relative length is a W3C standard that is not implemented
in any of the major browsers. Relative length is a way of splitting all
available pixels (if a table length is 100 pixels, and the first columngroup uses
20 px, and the second uses 50%, available pixels will
be 30px). The available pixels are shared using parts, one part is set
like this: "1*". The available pixels are divided into the set parts.
Example: If 30 pixels are available, you can have one relative length
"1*" and one "2*", this will be interpreted as 10 and 20 pixels (think
of this as 1* = 1 part, and 2* = 2 parts). |
Browser Support
The attribute is supported in all major browsers.
Note: None of the browsers support the relative_length value of this attribute.
