    <p>If <code>mutate</code> creates new columns, and the argument <code>copy_cell_props</code>
is missing or <code>TRUE</code>, then cell and column properties will be copied from
existing columns to their left, if there are any. Otherwise, they will be the
standard defaults. Row and table properties, and properties of cells in
existing columns, remain unchanged.</p>
