Using COL

The attribute RULES of the TABLE element is set to "groups", which has no effect in this sample. If RULES did work, there would be a table internal dividing line between the two columns in red and the blue column. For this attribute to work, you must use COLSPAN to define the groups of columns.

This column is in the first group.	This column is in the first group.	This column is in the second group.
This column is in the first group.	This column is in the first group.	This column is in the second group.
