HTML Table Colgroup
If you want to style the two first columns of a table, use the <colgroup> and <col> elements.
| MON | TUE | WED | THU | FRI | SAT | SUN |
|---|---|---|---|---|---|---|
| 1 | 2 | 3 | 4 | 5 | 6 | 7 |
| 8 | 9 | 10 | 11 | 12 | 13 | 14 |
| 15 | 16 | 17 | 18 | 19 | 20 | 21 |
| 22 | 23 | 24 | 25 | 26 | 27 | 28 |
The <colgroup> element should be used as a container for the column specifications.
Each group is specified with a <col> element.
The span attribute specifies how many columns that get the style.
The style attribute specifies the style to give the columns.
Note: There is a very limited selection of legal CSS properties for colgroups.

All other CSS properties will have no effect on your tables.
