text-grid-rs

A library to create formatted plain-text tables.

Example

use text_grid::*;
struct RowData {
    a: String,
    b: u32,
    c: u32,
    d: f64,
}
impl Cells for RowData {
    fn fmt(f: &mut CellsFormatter<Self>) {
        f.column("a", |s| &s.a);
        f.column("b", |s| s.b);
        f.column("c", |s| cell(s.c).left());
        f.column_with("d", |f| {
            f.column("x", |s| s.d);
            f.column("y", |s| cells_f!("{:.2e}", s.d));
        });
    }
}

let rows = [
    RowData { a: "ABC".to_string(), b: 300, c: 1,   d: 100.1 },
    RowData { a: "XY".to_string(),  b: 2,   c: 200, d: 1.234 },
];
let g = to_grid(rows);
assert_eq!(format!("\n{g}"), OUTPUT);

const OUTPUT: &str = r#"
  a  |  b  |  c  |         d          |
-----|-----|-----|--------------------|
     |     |     |    x    |    y     |
-----|-----|-----|---------|----------|
 ABC | 300 | 1   | 100.1   | 1.00 e 2 |
 XY  |   2 | 200 |   1.234 | 1.23 e 0 |
