Table

GoDoc

Pretty-print tables into ASCII/Unicode strings.

  • Add Rows one-by-one or as a group
  • Add Header(s) and Footer(s)
  • Auto Index Rows (1, 2, 3 ...) and Columns (A, B, C, ...)
  • Limit the length of the Rows; limit the length of individual Columns
  • Alignment - Horizontal & Vertical
    • Auto (horizontal) Align (numeric columns are aligned Right)
    • Custom (horizontal) Align per column
    • Custom (vertical) VAlign per column (and multi-line column support)
  • Mirror output to an io.Writer object (like os.StdOut)
  • Completely customizable styles
    • Many ready-to-use styles: style.go
    • Colorize Headers/Body/Footers using github.com/fatih/color
    • Custom text-case for Headers/Body/Footers
    • Enable separators between each row
    • Render table without a Border
  • Render as:
    • (ASCII/Unicode) Table
    • CSV
    • HTML Table (with custom CSS Class)
    • Markdown Table
+-----+------------+-----------+--------+-----------------------------+
|   # | FIRST NAME | LAST NAME | SALARY |                             |
+-----+------------+-----------+--------+-----------------------------+
|   1 | Arya       | Stark     |   3000 |                             |
|  20 | Jon        | Snow      |   2000 | You know nothing, Jon Snow! |
| 300 | Tyrion     | Lannister |   5000 |                             |
+-----+------------+-----------+--------+-----------------------------+
|     |            | TOTAL     |  10000 |                             |
+-----+------------+-----------+--------+-----------------------------+

A demonstration of all the capabilities can be found here: ../cmd/demo-table

If you want very specific examples, read ahead.

Examples

All the examples below are going to start with the following block, although nothing except a single Row is mandatory for the Render() function to render something:

package main

import (
    "os"

    "github.com/jedib0t/go-pretty/table"
)

func main() {
    t := table.NewWriter()
    t.SetOutputMirror(os.Stdout)
    t.AppendHeader(table.Row{"#", "First Name", "Last Name", "Salary"})
    t.AppendRows([]table.Row{
        {1, "Arya", "Stark", 3000},
        {20, "Jon", "Snow", 2000, "You know nothing, Jon Snow!"},
    })
    t.AppendRow([]interface{}{300, "Tyrion", "Lannister", 5000})
    t.AppendFooter(table.Row{"", "", "Total", 10000})
    t.Render()
}

Running the above will result in:

+-----+------------+-----------+--------+-----------------------------+
|   # | FIRST NAME | LAST NAME | SALARY |                             |
+-----+------------+-----------+--------+-----------------------------+
|   1 | Arya       | Stark     |   3000 |                             |
|  20 | Jon        | Snow      |   2000 | You know nothing, Jon Snow! |
| 300 | Tyrion     | Lannister |   5000 |                             |
+-----+------------+-----------+--------+-----------------------------+
|     |            | TOTAL     |  10000 |                             |
+-----+------------+-----------+--------+-----------------------------+

Styles

You can customize almost every single thing about the table above. The previous example just defaulted to StyleDefault during Render(). You can use a ready-to-use style (as in style.go) or customize it as you want.

Ready-to-use Styles

Table comes with a bunch of ready-to-use Styles that make the table look really good. Set or Change the style using:

    t.SetStyle(table.StyleLight)
    t.Render()

to get:

┌─────┬────────────┬───────────┬────────┬─────────────────────────────┐
│   # │ FIRST NAME │ LAST NAME │ SALARY │                             │
├─────┼────────────┼───────────┼────────┼─────────────────────────────┤
│   1 │ Arya       │ Stark     │   3000 │                             │
│  20 │ Jon        │ Snow      │   2000 │ You know nothing, Jon Snow! │
│ 300 │ Tyrion     │ Lannister │   5000 │                             │
├─────┼────────────┼───────────┼────────┼─────────────────────────────┤
│     │            │ TOTAL     │  10000 │                             │
└─────┴────────────┴───────────┴────────┴─────────────────────────────┘

Or if you want to use a full-color mode, and don't care for boxes, use:

    t.SetStyle(table.StyleColoredBright)
    t.Render()

to get:

Roll your own Style

You can also roll your own style:

    t.SetStyle(table.Style{
        Name: "myNewStyle",
        Box: table.BoxStyle{
            BottomLeft:       "\\",
            BottomRight:      "/",
            BottomSeparator:  "v",
            Left:             "[",
            LeftSeparator:    "{",
            MiddleHorizontal: "-",
            MiddleSeparator:  "+",
            MiddleVertical:   "|",
            PaddingLeft:      "<",
            PaddingRight:     ">",
            Right:            "]",
            RightSeparator:   "}",
            TopLeft:          "(",
            TopRight:         ")",
            TopSeparator:     "^",
            UnfinishedRow:    " ~~~",
        },
        Color: table.ColorOptions{
            AutoIndexColumn: nil,
            FirstColumn:     nil,
            Footer:          text.Colors{color.BgCyan, color.FgBlack},
            Header:          text.Colors{color.BgHiCyan, color.FgBlack},
            Row:             text.Colors{color.BgHiWhite, color.FgBlack},
            RowAlternate:    text.Colors{color.BgWhite, color.FgBlack},
        },
        Format: table.FormatOptions{
            Footer: text.FormatUpper,
            Header: text.FormatUpper,
            Row:    text.FormatDefault,
        },
        Options: table.Options{
            DrawBorder:      true,
            SeparateColumns: true,
            SeparateFooter:  true,
            SeparateHeader:  true,
            SeparateRows:    false,
        },
    })

Or you can use one of the ready-to-use Styles, and just make a few tweaks:

    t.SetStyle(table.StyleLight)
    t.Style().Color.Header = text.Colors{color.BgHiCyan, color.FgBlack}
    t.Style().Format.Footer = text.FormatLower
    t.Style().Options.DrawBorder = false

Wrapping (or) Row/Column Width restrictions

You can restrict the maximum (text) width for a Row:

    t.SetAllowedRowLength(50)
    t.Render()

to get:

+-----+------------+-----------+--------+------- ~
|   # | FIRST NAME | LAST NAME | SALARY |        ~
+-----+------------+-----------+--------+------- ~
|   1 | Arya       | Stark     |   3000 |        ~
|  20 | Jon        | Snow      |   2000 | You kn ~
| 300 | Tyrion     | Lannister |   5000 |        ~
+-----+------------+-----------+--------+------- ~
|     |            | TOTAL     |  10000 |        ~
+-----+------------+-----------+--------+------- ~

Or restrict the maximum (text) width for a Column:

    t.SetAllowedColumnLengths([]int{0, 6, 9, 6, 10})
    t.SetStyle(table.StyleRounded)
    t.Render()

to get:

╭─────┬────────┬───────────┬────────┬────────────╮
│   # │ FIRST  │ LAST NAME │ SALARY │            │
│     │ NAME   │           │        │            │
├─────┼────────┼───────────┼────────┼────────────┤
│   1 │ Arya   │ Stark     │   3000 │            │
│  20 │ Jon    │ Snow      │   2000 │ You know n │
│     │        │           │        │ othing, Jo │
│     │        │           │        │ n Snow!    │
│ 300 │ Tyrion │ Lannister │   5000 │            │
├─────┼────────┼───────────┼────────┼────────────┤
│     │        │ TOTAL     │  10000 │            │
╰─────┴────────┴───────────┴────────┴────────────╯

Column Control - Alignment & Colors

You can align text in columns horizontally and/or vertically. You can set up per-column color styles that will override the directives from the global Style set through SetStyle().

    t.SetAlign([]text.Align{text.AlignDefault, text.AlignRight, text.AlignDefault, text.AlignDefault, text.AlignCenter})
    t.SetVAlign([]text.VAlign{text.VAlignDefault, text.VAlignMiddle, text.VAlignBottom, text.VAlignMiddle})
    t.SetColors([]text.Colors{{color.FgWhite, color.BgBlack}, {color.FgWhite, color.BgBlack}})
    t.SetColorsFooter([]text.Colors{{color.FgRed}, {color.FgGreen}, {color.FgBlue}})
    t.SetColorsHeader([]text.Colors{{color.FgCyan}, {color.FgMagenta}, {color.FgYellow}, {color.FgBlack, color.BgWhite}})
