Example 2 - Without Border / Footer / Bulk Append

data := [][]string{
    []string{"1/1/2014", "Domain name", "2233", "$10.98"},
    []string{"1/1/2014", "January Hosting", "2233", "$54.95"},
    []string{"1/4/2014", "February Hosting", "2233", "$51.00"},
    []string{"1/4/2014", "February Extra Bandwidth", "2233", "$30.00"},
}

table := tablewriter.NewWriter(os.Stdout)
table.SetHeader([]string{"Date", "Description", "CV2", "Amount"})
table.SetFooter([]string{"", "", "Total", "$146.93"}) // Add Footer
table.SetBorder(false)                                // Set Border to false
table.AppendBulk(data)                                // Add Bulk Data
table.Render()

Output 2

                                      +-------+---------+

Example 3 - CSV

table, _ := tablewriter.NewCSV(os.Stdout, "test_info.csv", true)
table.SetAlignment(tablewriter.ALIGN_LEFT)   // Set Alignment
table.Render()

Output 3

+----------+--------------+------+-----+---------+----------------+
|  FIELD   |     TYPE     | NULL | KEY | DEFAULT |     EXTRA      |
+----------+--------------+------+-----+---------+----------------+
| user_id  | smallint(5)  | NO   | PRI | NULL    | auto_increment |
| username | varchar(10)  | NO   |     | NULL    |                |
| password | varchar(100) | NO   |     | NULL    |                |
+----------+--------------+------+-----+---------+----------------+

Example 4 - Custom Separator

table, _ := tablewriter.NewCSV(os.Stdout, "test.csv", true)
table.SetRowLine(true)         // Enable row line

// Change table lines
table.SetCenterSeparator("*")
table.SetColumnSeparator("‡")
table.SetRowSeparator("-")

table.SetAlignment(tablewriter.ALIGN_LEFT)
table.Render()

Output 4

*------------*-----------*---------*
╪ FIRST NAME ╪ LAST NAME ╪   SSN   ╪
*------------*-----------*---------*

Example 5 - Markdown Format

data := [][]string{
	[]string{"1/1/2014", "Domain name", "2233", "$10.98"},
	[]string{"1/1/2014", "January Hosting", "2233", "$54.95"},
	[]string{"1/4/2014", "February Hosting", "2233", "$51.00"},
	[]string{"1/4/2014", "February Extra Bandwidth", "2233", "$30.00"},
}

table := tablewriter.NewWriter(os.Stdout)
table.SetHeader([]string{"Date", "Description", "CV2", "Amount"})
table.SetBorders(tablewriter.Border{Left: true, Top: false, Right: true, Bottom: false})
table.SetCenterSeparator("|")
table.AppendBulk(data) // Add Bulk Data
table.Render()

Output 5

|   DATE   |       DESCRIPTION        | CV2  | AMOUNT |
|----------|--------------------------|------|--------|
| 1/1/2014 | Domain name              | 2233 | $10.98 |

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

table.SetHeaderColor(tablewriter.Colors{tablewriter.Bold, tablewriter.BgGreenColor},

table.SetColumnColor(tablewriter.Colors{tablewriter.Bold, tablewriter.FgHiBlackColor},
	tablewriter.Colors{tablewriter.Bold, tablewriter.FgHiRedColor},
	tablewriter.Colors{tablewriter.Bold, tablewriter.FgHiBlackColor},
	tablewriter.Colors{tablewriter.Bold, tablewriter.FgBlackColor})

table.SetFooterColor(tablewriter.Colors{}, tablewriter.Colors{},
	tablewriter.Colors{tablewriter.Bold},
	tablewriter.Colors{tablewriter.FgHiRedColor})

table.AppendBulk(data)
table.Render()

Table with color Output

Example 6 - Set table caption

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"})
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.

Output 6

+------+-----------------------+--------+
| NAME |         SIGN          | RATING |
