Overview

The package implements a write filter that translates tabbed columns in input into properly aligned text. The package is using the Elastic Tabstops algorithm described at http://nickgravgaard.com/elastictabstops/index.html.

tw := tabwriter.NewWriter(os.Stdout, 0, 1, 2, ' ', 0)
defer tw.Flush()
fmt.Fprintf(tw, "Column A\tColumn B\tColumn C\n")
fmt.Fprintf(tw, "a\tbbbbbb\tccc\n")
fmt.Fprintf(tw, "aaaa\tbb\tccc\n")
fmt.Fprintf(tw, "aaaaaaaaaaaaa\tb\tcccc\n")

produces

Column A       Column B  Column C
a              bbbbbb    ccc
aaaa           bb        ccc
aaaaaaaaaaaaa  b         cccc
