width                                             (Assignable)

        Contains a numeric value that defines the display width for the
        column.  If TBColumn:width is not explicitly set, the width of the
        column will be the greater of: the length of the heading, the length
        of the footing, or the length of the data at the first evaluation of
        TBColumn:block.

        If this instance variable is explicitly set, the width of the column
        will be TBColumn:width.  Displayed headings, footings, and data will
        all be truncated to this width when necessary.  The width of the
        displayed data will be the length at the first evaluation of
        TBColumn:block for all data types other than character.  Character
        data will be extended to TBColumn:width for display purposes.
