table

Produces a string that represents slice of structs data in a text table, inspired by gajus/table.

Features:

• No dependency.
• Cell content aligned.
• Column width self-adaptation
• Support type of struct field: int, float, string, bool, slice, struct, map, time.Time and everything.
• Support custom table header by declaring optional tag: table.(Thanks @skyfireitdiy)

Installation

$ go get github.com/modood/table

Quick start

goCopy
package main

import (
	"github.com/modood/table"
)

type House struct {
	Name  string `table:"Name"`
	Sigil string
	Motto string
}

func main() {
	hs := []House{
		{"Stark", "direwolf", "Winter is coming"},
		{"Targaryen", "dragon", "Fire and Blood"},
		{"Lannister", "lion", "Hear Me Roar"},
	}

	// Output to stdout
	table.Output(hs)

	// Or just return table string and then do something
	s := table.Table(hs)
	_ = s
}

output:

┌───────────┬──────────┬──────────────────┐
│ Name      │ Sigil    │ Motto            │
├───────────┼──────────┼──────────────────┤
│ Stark     │ direwolf │ Winter is coming │
│ Targaryen │ dragon   │ Fire and Blood   │
│ Lannister │ lion     │ Hear Me Roar     │
└───────────┴──────────┴──────────────────┘

Document

• func Output(slice interface{})

  formats slice of structs data and writes to standard output.(Using box drawing characters)

• func OutputA(slice interface{})

  formats slice of structs data and writes to standard output.(Using standard ascii characters)

• func Table(slice interface{}) string

  formats slice of structs data and returns the resulting string.(Using box drawing characters)

• func AsciiTable(slice interface{}) string

  formats slice of structs data and returns the resulting string.(Using standard ascii characters)

• compare box drawing characters with standard ascii characters

  box drawing:

  ┌───────────┬──────────┬──────────────────┐
  │ Name      │ Sigil    │ Motto            │
  ├───────────┼──────────┼──────────────────┤
  │ Stark     │ direwolf │ Winter is coming │
  │ Targaryen │ dragon   │ Fire and Blood   │
  │ Lannister │ lion     │ Hear Me Roar     │
  └───────────┴──────────┴──────────────────┘
  

  standard ascii:
