Is it possible to set an individual column in a TkTable to be a
different width than the default?

I'm looking at http://tcl.activestate.com/community/hobbs/tcl/.  It
looks like I should be able to do something like

 @table.tag_col('WideCol', 2)
 @table.width('WideCol', 20)

Which would tag the second column with 'WideCol' and then set all
columns that are tagged with 'WideCol' to width 20.  But #width() just
wants one argument, although the tcl docs look like it can support
more.

Thanks,
Joe
