Example 1 - Basic
data := [][]string{
    []string{"A", "The Good", "500"},
    []string{"B", "The Very very Bad Man", "288"},
    []string{"C", "The Ugly", "120"},
    []string{"D", "The Gopher", "800"},
}

table := tablewriter.NewWriter(os.Stdout)
table.SetHeader([]string{"Name", "Sign", "Rating"})

for _, v := range data {
    table.Append(v)
}
table.Render() // Send output
Output 1

table.SetFooter([]string{"", "", "Total", "$146.93"}) // Add Footer
table.SetBorder(false)                                // Set Border to false
table.AppendBulk(data)                                // Add Bulk Data

Example 9 - Set table caption

table.SetHeader([]string{"Name", "Sign", "Rating"})
table.SetCaption(true, "Movie ratings.")

for _, v := range data {
    table.Append(v)
}
table.Render() // Send output

Note: Caption text will wrap with total width of rendered table.

Example 10 - Set NoWhiteSpace and TablePadding option

    {"node3.example.com", "Ready", "compute", "1.11"},

table := tablewriter.NewWriter(os.Stdout)
table.SetHeader([]string{"Name", "Status", "Role", "Version"})
table.SetAutoWrapText(false)
table.SetAutoFormatHeaders(true)
table.SetHeaderAlignment(ALIGN_LEFT)
table.SetAlignment(ALIGN_LEFT)
table.SetCenterSeparator("")
table.SetColumnSeparator("")
table.SetRowSeparator("")
table.SetHeaderLine(false)
table.SetBorder(false)
table.SetTablePadding("\t") // pad with tabs
table.SetNoWhiteSpace(true)
table.AppendBulk(data) // Add Bulk Data
table.Render()
Output 10

Render table into a string

Instead of rendering the table to io.Stdout you can also render it into a string. Go 1.10 introduced the strings.Builder type which implements the io.Writer interface and can therefore be used for this task. Example:

package main

import (
    "strings"
    "fmt"

    "github.com/olekukonko/tablewriter"
)

func main() {
    tableString := &strings.Builder{}
    table := tablewriter.NewWriter(tableString)

    /*
     * Code to fill the table
     */

    table.Render()

    fmt.Println(tableString.String())
}

Create & Generate text based table

Example (Autowrap)
var multiline = `A multiline
string with some lines being really long.`

const (
	testRow = iota
	testHeader
	testFooter
	testFooter2
)
for mode := testRow; mode <= testFooter2; mode++ {
	for _, autoFmt := range []bool{false, true} {
		if mode == testRow && autoFmt {
			// Nothing special to test, skip
			continue
		}
		for _, autoWrap := range []bool{false, true} {
			for _, reflow := range []bool{false, true} {
				if !autoWrap && reflow {
					// Invalid configuration, skip
					continue
				}
				fmt.Println("mode", mode, "autoFmt", autoFmt, "autoWrap", autoWrap, "reflow", reflow)
				t := NewWriter(os.Stdout)
				t.SetAutoFormatHeaders(autoFmt)
				t.SetAutoWrapText(autoWrap)
				t.SetReflowDuringAutoWrap(reflow)
				if mode == testHeader {
					t.SetHeader([]string{"woo", multiline})
				} else {
					t.SetHeader([]string{"woo", "waa"})
				}
				if mode == testRow {
					t.Append([]string{"woo", multiline})
				} else {
					t.Append([]string{"woo", "waa"})
				}
				if mode == testFooter {
					t.SetFooter([]string{"woo", multiline})
				} else if mode == testFooter2 {
					t.SetFooter([]string{"", multiline})
				} else {
					t.SetFooter([]string{"woo", "waa"})
				}
				t.Render()
			}
		}

Functions

func Color

func Color(colors ...int) []int

func ConditionString

func ConditionString(cond bool, valid, inValid string) string

Simple Condition for string Returns value based on condition

func DisplayWidth

func DisplayWidth(str string) int

func Pad

func Pad(s, pad string, width int) string

Pad String Attempts to place string in the center

func PadLeft

func PadLeft(s, pad string, width int) string

func PadRight

func PadRight(s, pad string, width int) string

Pad String Right position This would place string at the left side of the screen

func Title

func Title(name string) string

Format Table Header Replace _ , . and spaces

func WrapString

func WrapString(s string, lim int) ([]string, int)

Wrap wraps s into a paragraph of lines of length lim, with minimal raggedness.

func WrapWords

func WrapWords(words []string, spc, lim, pen int) [][]string

WrapWords is the low-level line-breaking algorithm, useful if you need more control over the details of the text wrapping process. For most uses, WrapString will be sufficient and more convenient.

WrapWords splits a list of words into lines with minimal "raggedness", treating each rune as one unit, accounting for spc units between adjacent words on each line, and attempting to limit lines to lim units. Raggedness is the total error over all lines, where error is the square of the difference of the length of the line and lim. Too-long lines (which only happen when a single word is longer than lim units) have pen penalty units added to the error.
