Macro tbl 

macro_rules! tbl {
    ($name:expr, $($col:expr),+ $(,)?) => { ... };
    ($name:expr) => { ... };
}

Ergonomic constructor for a Table from named columns.

The first argument is the table name. Subsequent arguments are FieldArray columns, comma-separated. An empty table is built when only a name is provided.

Example

use minarrow::{fa_f64, fa_i32, tbl};

let t = tbl!("orders",
    fa_i32!("id", 1, 2, 3),
    fa_f64!("qty", 10.0, 20.0, 30.0),
);
assert_eq!(t.name, "orders");
assert_eq!(t.cols.len(), 2);
assert_eq!(t.n_rows, 3);
