Crate lil_tabby 

Macro wrapper over tabled crate, allowing to create tables inplace or from Vec<Vec<String>> treating first data row both as data or as header overcoming specific cont trait treatment as originally in tabled.

Features

• Automatic Column Spanning: Rows with fewer columns automatically span to fill the table
• Customizable Styling: Configure table style, header color, first column color, content color, border color, and bold headers
• Simple Macro Syntax: Create tables inline or from existing collections
• Extensible: Use the re-exported tabled module for advanced customization

Examples

Basic Table with Literal Data

use lil_tabby::tabby;

let t = tabby![
    { style: ascii }
    ["Header 1", "Header 2", "Header 3"],
    ["Short", "Row"], // Auto-spans to fill remaining columns
    ["Full", "Width", "Row"]
];
println!("{}", t);

Output:

+----------+----------+----------+
| Header 1 | Header 2 | Header 3 |
+----------+----------+----------+
| Short    | Row      |          |
+----------+----------+----------+
| Full     | Width    | Row      |
+----------+----------+----------+

Styled Table with Custom Options

use lil_tabby::tabby;

let t = tabby![
    { style: modern_rounded, header: green, labels: yellow, color: blue, border: red, bold: true }
    ["Header 1", "Header 2", "Header 3"],
    ["Short", "Row"],
    ["Full", "Width", "Row"]
];
println!("{}", t);

Table from Vec<Vec<String>>

use lil_tabby::tabby;

let data: Vec<Vec<String>> = vec![
    vec!["Header 1".to_string(), "Header 2".to_string(), "Header 3".to_string()],
    vec!["Row 1".to_string()],
    vec!["Row 2 Col 1".to_string(), "Row 2 Col 2".to_string()]
];
let t = tabby!(data);
println!("{}", t);

Post-Creation

Just re-export tabled

use lil_tabby::{tabby, tabled};

let mut table = tabby![
    { style: ascii_rounded, border: bright_green }
    ["a", "b", "c"],
    ["c", "d"],
    ["e"]
];
table.modify(tabled::settings::object::Columns::new(0..), tabled::settings::Alignment::right());
println!("{}", table);

Output:

+---+---+---+
| a | b | c |
+---+---+---+
| d |     e |
+---+-------+
|         f |
+-----------+

Styling Options

The tabby! macro accepts an optional styling block with these parameters:

• style: Table style (e.g., modern_rounded, ascii_rounded, markdown). Defaults to modern_rounded. Maps to tabled::settings::Style
• header: First row color (e.g., green, blue, red). Defaults to white. All colors mapped to tabled::settings::Color::FG_<COLOR>
• labels: First column color (e.g., yellow, cyan). Defaults to white
• color: Content color (e.g., blue, magenta). Defaults to white
• border: Border color (e.g., red, bright_green). Defaults to bright_black
• bold: Whether the header row is bold (true or false). Defaults to false

Limitations

• Table limited to 20 columns, due to const trait implementation, each used size should be covered. So, 20 like 640kb, enough, anyway wont fit the screen.
