Deferring updating column widths until the redraw loop executes in a finally command.  Currently, every time the user adds or removes a column, we refresh the widths of all columns.  This leads to an O(n^2) creation time for the table.  Resetting the column widths in the redraw loop reduces that to O(n), and is consistent with the rendering implementation of the table itself.  We use a dirty bit to indicate that the column widths need to be updated, to avoid unnecessary work in the redraw loop.  When setting or clearing column widths, we update the affectected col element synchronously.
