Examples

use text_grid::*;
let s = cells_schema::<f64>(|f| {
    f.column("",      |x| cell!("{x:e}"));
    f.column("e",     |x| cells_f!("{x:e}"));
    f.column(".2e",   |x| cells_f!("{x:.2e}"));
    f.column("E",     |x| cells_f!("{x:E}"));
    f.column("debug", |x| cells_f!("{x:?}"));
});

let g = to_grid_with_schema(vec![1.0, 0.95, 123.45, 0.000001, 1.0e-20, 10000000000.0], s);
