The default table might look not very representative. But it's considered that you might improve it by suplying your own CSS.

In a mean time there's some regular style options.

Also notice that table elements does not have any special id, class attributes. It's supposed that you might add them if necessary your self, by using HtmlTable::visit_mut

Adding custom ids example.

use table_to_html::{HtmlTable, html::{Attribute, HtmlVisitorMut, HtmlElement}};

struct CellIdIndex {
    i: usize
}

impl HtmlVisitorMut for CellIdIndex {
    fn visit_element_mut(&mut self, e: &mut HtmlElement) -> bool {
        if e.tag() == "td" {
            let mut attrs = e.attrs().to_vec();
            attrs.push(Attribute::new("id", self.i.to_string()));
            *e = HtmlElement::new("td", attrs, e.value().cloned());
            self.i += 1;
        } else if e.tag() == "th" {
            let mut attrs = e.attrs().to_vec();
            attrs.push(Attribute::new("id", self.i.to_string()));
            *e = HtmlElement::new("th", attrs, e.value().cloned());
            self.i += 1;
        }

        true
    }
}

let data = vec![
    vec!["Debian", "", "0"],
    vec!["Arch", "", "0"],
    vec!["Manjaro", "Arch", "0"],
];

let mut html_table = HtmlTable::new(data);
html_table.visit_mut(CellIdIndex{ i: 0 });
