It was not part of HTML 3.2 for the simple reason it didn't work
across a wide range of browsers as of early 1996. Note that the
browser can automatically work out how wide columns need to be based
upon their content.  The richer model in RFC 1942 allows you to
optionally set column widths in absolute or relative terms. This
is now supported by some browsers and is being considered for
incorporation in the next version of HTML from W3C.  I am also
working on a proposal for specifying table presentation properties
in CSS, including column widths, row heights, borders, alignment
and other properties.
