     * Specifically, it sets the column's minimum and maximum widths to
     * its preferred width, and disables auto-resize for the table as a
     * whole.
     *
     * <p>
     *
     * Later on this should take a column array for efficiency.

     * @param colIndex int Which column to fix
     * @return int The width of the column as it was fixed
