Attributes

align
The align attribute is used to set the horizontal alignment of the cell contents. The possible values are center, char, justify, left, and right.

char
The char attribute permits you to select a character that will be used to align the contents of the cells in a column. This was designed to allow the decimal points in a column of numbers to be in vertical alignment. The default value is country dependent. In the U.S., it is the first occurrence of a period or a decimal point.

charoff
The charoff attribute is an integer used to specify if the value designated in the char attribute is to be the first, second, or whatever occurrence.

span
The span attribute is used to set the number of columns that are associated with each column group. If the columns are dissimilar, however, use the col tag to create each column, rather than this attribute.

valign
The valign attribute is used to set the vertical alignment of the cell contents. The possible values are baseline, bottom, middle, and top.

width
The width attribute is used to set the width of each of the spanned columns. The value can be a percentage of the total width or an integer number of pixels.
