width

This 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.
