<colgroup>

Obsolete attributes

char

This attribute specifies the alignment of the content in a column group to a character. Typical values for this include a period (.) when attempting to align numbers or monetary values. If align is not set to char, this attribute is ignored, though it will still be used as the default value for the align of the <col> which are members of this column group.

Note: To achieve the same effect as the char attribute, in CSS3, you can use the character set using the char attribute as the value of the text-align property Unimplemented.

charoff

This attribute is used to indicate the number of characters to offset the column data from the alignment character specified by the char attribute.

valign

This attribute specifies the vertical alignment of the text within each cell of the column. Possible values for this attribute are:

• baseline, which will put the text as close to the bottom of the cell as it is possible, but align it on the baseline of the characters instead of the bottom of them. If characters are all of the size, this has the same effect as bottom.
• bottom, which will put the text as close to the bottom of the cell as it is possible;
• middle, which will center the text in the cell;
• and top, which will put the text as close to the top of the cell as it is possible.

Note:

• Do not try to set the vertical-align property on a selector giving a <colgroup> element. Because <td> elements are not descendant of the <colgroup> element, they won't inherit it.
• If the table doesn't use a colspan attribute, use the td:nth-child(an+b) CSS selector per column, where a is the total number of the columns in the table and b is the ordinal position of the column in the table. Only after this selector the vertical-align property can be used.
• If the table does use a colspan attribute, the effect can be achieved by combining adequate CSS attribute selectors like [colspan=n], though this is not trivial.
