cli-table
Rust crate for printing tables on command line.
Usage
Add cli-table
in your Cargo.toms

[dependencies]
cli-table = "0.4"
Simple usage
use cli_table::{format::Justify, print_stdout, Cell, Style, Table};
let table = vec![
vec!["Tom".cell(), 10.cell().justify(Justify::Right)],
vec!["Jerry".cell(), 15.cell().justify(Justify::Right)],
vec!["Scooby Doo".cell(), 20.cell().justify(Justify::Right)],
]
.table()
.title(vec![
"Name".cell().bold(true),
"Age (in years)".cell().bold(true),
])
.bold(true);
assert!(print_stdout(table).is_ok());
Below is the output of the table we created just now:
+------------+----------------+
| Name | Age (in years) | <-- This row and all the borders/separators
+------------+----------------+ will appear in bold
| Tom | 10 |
+------------+----------------+
| Jerry | 15 |
+------------+----------------+
| Scooby Doo | 25 |
+------------+----------------+
Display
trait implementation
To get a Display
trait implementation of TableStruct
, use display()
function on the struct to get an instance
of TableDisplay
which implements Display
trait.
use cli_table::{format::Justify, Cell, Style, Table};
let table = vec![
vec!["Tom".cell(), 10.cell().justify(Justify::Right)],
vec!["Jerry".cell(), 15.cell().justify(Justify::Right)],
vec!["Scooby Doo".cell(), 20.cell().justify(Justify::Right)],
]
.table()
.title(vec![
"Name".cell().bold(true),
"Age (in years)".cell().bold(true),
])
.bold(true);
let table_display = table.display().unwrap();
println!("{}", table_display);
Below is the output of the table we created just now:
+------------+----------------+
| Name | Age (in years) | <-- This row and all the borders/separators
+------------+----------------+ will appear in bold
| Tom | 10 |
+------------+----------------+
| Jerry | 15 |
+------------+----------------+
| Scooby Doo | 25 |
+------------+----------------+
Derive macro
#[derive(Table)]
can also be used to print a Vec
or slice of struct
s as table.
use cli_table::{format::Justify, print_stdout, Table, WithTitle};
#[derive(Table)]
struct User {
#[table(title = "ID", justify = "Justify::Right")]
id: u64,
#[table(title = "First Name")]
first_name: &'static str,
#[table(title = "Last Name")]
last_name: &'static str,
}
let users = vec![
User {
id: 1,
first_name: "Scooby",
last_name: "Doo",
},
User {
id: 2,
first_name: "John",
last_name: "Cena",
},
];
assert!(print_stdout(users.with_title()).is_ok());
Below is the output of the table we created using derive macro:
+----+------------+-----------+
| ID | First Name | Last Name | <-- This row will appear in bold
+----+------------+-----------+
| 1 | Scooby | Doo |
+----+------------+-----------+
| 2 | John | Cena |
+----+------------+-----------+
Field attributes
title
|name
: Used to specify title of a column. Usage:#[table(title = "Title")]
justify
: Used to horizontally justify the contents of a column. Usage:#[table(justify = "Justify::Right")]
align
: Used to vertically align the contents of a column. Usage:#[table(align = "Align::Top")]
color
: Used to specify color of contents of a column. Usage:#[table(color = "Color::Red")]
bold
: Used to specify boldness of contents of a column. Usage:#[table(bold)]
order
: Used to order columns in a table while printing. Usage:#[table(order = <usize>)]
. Here, columns will be sorted based on their order. For e.g., column withorder = 0
will be displayed on the left followed by column withorder = 1
and so on.display_fn
: Used to print types which do not implementDisplay
trait. Usage#[table(display_fn = "<func_name>")]
. Signature of provided function should befn <func_name>(value: &<type>) -> impl Display
.customize_fn
: Used to customize style of a cell. Usage#[table(customize_fn = "<func_name>")]
. Signature of provided function should befn <func_name>(cell: CellStruct, value: &<type>) -> CellStruct
. This attribute can be used when you want to change the formatting/style of a cell based on its contents. Note that this will overwrite all the style settings done by other attributes.skip
: Used to skip a field from table. Usage:#[table(skip)]
For more information on configurations available on derive macro, go to cli-table/examples/struct.rs
.
CSV
This crate also integrates with csv
crate. On enabling "csv"
feature, you can
use TryFrom<&mut Reader> for TableStruct
trait implementation to convert csv::Reader
to TableStruct
.
For more information on handling CSV values, go to cli-table/examples/csv.rs
.
Styling
Style of a table/cell can be modified by calling functions of Style
trait. It is implementated by both
TableStruct
and CellStruct
.
For individually formatting each cell of a table, justify
, align
and padding
functions can be used from
CellStruct
.
In addition to this, borders and separators of a table can be customized by calling border
and separator
functions in TableStruct
. For example, to create a borderless table:
use cli_table::{Cell, Table, TableStruct, format::{Justify, Border}, print_stdout};
fn get_table() -> TableStruct {
vec![
vec!["Tom".cell(), 10.cell().justify(Justify::Right)],
vec!["Jerry".cell(), 15.cell().justify(Justify::Right)],
vec!["Scooby Doo".cell(), 20.cell().justify(Justify::Right)],
]
.table()
}
let table = get_table().border(Border::builder().build()); // Attaches an empty border to the table
assert!(print_stdout(table).is_ok());
Features
