Crate cli_table_derive[−][src]
Rust crate for printing tables on command line.
Usage
Add cli-table
in your Cargo.toms
’s dependencies
section
[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 |
+------------+----------------+
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
.skip
: Used to skip a field from table. Usage:#[table(skip)]

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

Features
derive
: Enables derive macro for creating tables using structs. Enabled by default.csv
: Enables support for printing tables usingcsv
. Enabled by default.
