span [0..1]xsd:nonNegativeIntegerThis attribute, which must be an integer > 0, specifies the number of columns in a column group. In the absence of a span attribute, each colgroup defines a column group containing one column. If the span attribute is set to N > 0, the current colgroup element defines a column group containing N columns. User agents must ignore this attribute if the colgroup element contains one or more col elements.from group db.html.colgroup.attlist
width [0..1]xsd:anySimpleTypeThis attribute specifies a default width for each column in the current column group. In addition to the standard pixel, percentage, and relative values, this attribute allows the special form 0* (zero asterisk) which means that the width of the each column in the group should be the minimum width necessary to hold the column's contents. This implies that a column's entire contents must be known before its width may be correctly computed. Authors should be aware that specifying 0* will prevent visual user agents from rendering a table incrementally. This attribute is overridden for any column in the column group whose width is specified via a col element.from group db.html.colgroup.attlist
align [0..1]AnonymousSpecifies the alignment of data and the justification of text in a cell.from group db.html.cellhalign
char [0..1]xsd:anySimpleTypeThis attribute specifies a single character within a text fragment to act as an axis for alignment. The default value for this attribute is the decimal point character for the current language as set by the lang attribute (e.g., the period in English and the comma in French). User agents are not required to support this attribute.from group db.html.cellhalign
charoff [0..1]AnonymousWhen present, this attribute specifies the offset to the first occurrence of the alignment character on each line. If a line doesn't include the alignment character, it should be horizontally shifted to end at the alignment position. When charoff is used to set the offset of an alignment character, the direction of offset is determined by the current text direction (set by the dir attribute). In left-to-right texts (the default), offset is from the left margin. In right-to-left texts, offset is from the right margin. User agents are not required to support this attribute.from group db.html.cellhalign
valign [0..1]AnonymousSpecifies the vertical position of data within a cell.from group db.html.cellvalign
