&'v mut self,
annotation: A,

) -> Result<(), Error>where

pub fn assign_cell<'v, V, VR, A, AR>( &'v mut self, annotation: A, column: TableColumn, offset: usize, to: V ) -> Result<(), Error>where V: FnMut() -> Value<VR> + 'v, VR: Into<Assigned<F>>, A: Fn() -> AR, AR: Into<String>,
Assigns a fixed value to a table cell.
Returns an error if the table cell has already been assigned to.
Even though to
has FnMut
bounds, it is guaranteed to be called at most once.
