This library displays ascii tables that automatically fit in your terminal and handle most data structures.
To have it in a lein project, add to your project.clj:
[table "0.5.0"]
To have it in a deps.edn project, add to your deps.edn:
{table/table {:mvn/version "0.5.0"}}
To use with babashka, add to bb.edn.
table handles rendering combinations of maps, vecs, lists and sets nested in one another.
$ lein repl
user=> (require '[table.core :as t])
nil
; These three yields the same table
user=> (t/table [["1" "2"] ["3" "4"]])
user=> (t/table '((1 2) (3 4)))
user=> (t/table #{[1 2] [3 4]})
+---+---+
| 1 | 2 |
+---+---+
| 3 | 4 |
+---+---+
user=> (t/table [{:a 11} {:a 3 :b 22}])
+----+----+
| a | b |
+----+----+
| 11 | |
| 3 | 22 |

table can render different styles of tables:
user=> (t/table [ [1 2] [3 4]] :style :unicode)
┌───┬───┐
│ 1 │ 2 │
├───┼───┤
│ 3 ╎ 4 │
└───┴───┘
user=> (t/table [ [1 2] [3 4]] :style :org)
|---+---|
| 1 | 2 |
|---+---|
| 3 | 4 |
|---+---|
# Yes, these will generate tables for github's markdown
user=> (t/table [ [10 20] [3 4]] :style :github-markdown)
| 10 | 20 |
|--- | ---|
| 3 | 4 |
table can also render custom styles:
user> (t/table [[10 20] [3 4]] :style {:top ["◤ " " ▼ " " ◥"]
:top-dash "✈︎"
:middle ["▶︎ " " " " ◀︎"]
:dash "✂︎"
:bottom ["◣ " " ▲ " " ◢"]
:bottom-dash "☺︎"
:header-walls [" " " " " "]
:body-walls [" " " " " "] })
◤ ✈︎✈︎ ▼ ✈︎✈︎ ◥
10 20
▶︎ ✂︎✂︎ ✂︎✂︎ ◀︎
3 4
◣ ☺︎☺︎ ▲ ☺︎☺︎ ◢
table can handle plain maps and vectors of course:
user=> (t/table (meta #'doc))
+-----------+---------------------------------------------------------------+
| key | value |
+-----------+---------------------------------------------------------------+
| :macro | true |
| :ns | clojure.repl |
| :name | doc |
| :arglists | ([name]) |
| :added | 1.0 |
| :doc | Prints documentation for a var or special form given its name |
| :line | 120 |
| :file | clojure/repl.clj |
+-----------+---------------------------------------------------------------+
user=> (t/table (seq (.getURLs (java.lang.ClassLoader/getSystemClassLoader))))

If your terminal width isn't being auto-detected, you can execute this in your shell before using
the repl: export COLUMNS. Alternatively you can bind/alter table.width/*width* to your desired
width.
- Clojure 1.5.0 comes with a similar function clojure.pprint/print-table
- doric is more full-featured than print-table, supporting formats other than text.
table improves on these alternatives by rendering more data structures, supporting different ascii style tables and resizing to fit your terminal.
Please report them on github.
- Handle no rows
- Handle vecs with different sizes
- Escape tabs
