CLI Tables Made Easy

Example

use rand::Rng;
use term_table::{row, row::Row, rows, table_cell::*, Table, TableStyle};

fn main() {
    let mut rng = rand::thread_rng();
    let num_draws = 5;
    let num_numbers = 6;
    let range = 1..=99;

    let mut table = Table::builder()
        .rows(rows![row!(TableCell::builder("My Lucky Numbers")
            .alignment(Alignment::Center)
            .col_span(num_numbers))])
        .style(TableStyle::elegant())
        .build();

    for _ in 0..num_draws {
        let mut row = Row::empty();
        for _ in 0..num_numbers {
            let num: i32 = rng.gen_range(range.clone());
            row.add_cell(TableCell::new(num.to_string()));
        }
        table.add_row(row);
    }

    println!("{}", table.render());
}

Here's the result

Table Styles

It is possible to define your own table styles by creating a new instance of TableStyle

This is what the extend table style implementation looks like. This is the default style in term-table-rs

pub fn extended() -> TableStyle {
    return TableStyle {
        top_left_corner: '╔',
        top_right_corner: '╗',
        bottom_left_corner: '╚',
        bottom_right_corner: '╝',
        outer_left_vertical: '╠',
        outer_right_vertical: '╣',
        outer_bottom_horizontal: '╩',
        outer_top_horizontal: '╦',
        intersection: '╬',
        vertical: '║',
        horizontal: '═',
    };
}

TableStyle also implements a simple() table style function and a blank() table style function

Those styles looks like this

Column Widths

It is possible to control the maximum width of table columns. The max_column_width property of Table can be set to restrict the width of all TableCells. The set_max_column_width function of Table can be used to set the max width of a specific column. The set_max_column_widths function provides the ability to set the width of multiple columns by passing in a Vec of tuples containing an index and width.

Disabling Row Separators

There are a few different options for disabling row separation.

Table has three flags for controlling row separation:

1. separate_rows dictates whether rows are separated within the table

   

2. has_top_boarder dictates whether or not the table has a top border

   

3. has_bottom_boarder dictates whether or not the table has a bottom border

   

Separators can also be controlled per row by setting the has_separator flag on Row
