Package table provides a convenient way to generate tabular output of any data, primarily useful for CLI tools.

• Accepts all data types (string, int, interface{}, everything!) and will use the String() string method of a type if available.
• Can specify custom formatting for the header and first column cells for better readability.
• Columns are left-aligned and sized to fit the data, with customizable padding.
• The printed output can be sent to any io.Writer, defaulting to os.Stdout.
• Built to an interface, so you can roll your own Table implementation.
• Works well with ANSI colors (fatih/color in the example)!
• Can provide a custom WidthFunc to accomodate multi- and zero-width characters (such as runewidth)

Download the package:

go get github.com/rodaine/table

Example:

package main

import (
  "fmt"
  "strings"

  "github.com/fatih/color"
  "github.com/rodaine/table"
)

func main() {
  headerFmt := color.New(color.FgGreen, color.Underline).SprintfFunc()
  columnFmt := color.New(color.FgYellow).SprintfFunc()

  tbl := table.New("ID", "Name", "Score", "Added")
  tbl.WithHeaderFormatter(headerFmt).WithFirstColumnFormatter(columnFmt)

  for _, widget := range getWidgets() {
    tbl.AddRow(widget.ID, widget.Name, widget.Cost, widget.Added)
  }

  tbl.Print()
}
