Function to_delimited 

pub fn to_delimited<R, C, S>(rows: R, delimiter: char) -> String
where
    R: IntoIterator<Item = C>,
    C: IntoIterator<Item = Cell<S>>,
    S: AsRef<str>,

The table as delimited text with delimiter between fields ('\t' for TSV), laid out on its grid as the module describes.

A field holding the delimiter, a double quote or a line break is enclosed in double quotes, with each quote inside doubled; every other field is written as it is.
