#### Example   1 - Basic
```go
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
```
+------+-----------------------+--------+
| NAME |         SIGN          | RATING |
+------+-----------------------+--------+
|  A   |       The Good        |    500 |
|  B   | The Very very Bad Man |    288 |
|  C   |       The Ugly        |    120 |
|  D   |      The Gopher       |    800 |
+------+-----------------------+--------+
```

#### Example 2 - Without Border / Footer / Bulk Append
```go
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
```

    DATE   |       DESCRIPTION        |  CV2  | AMOUNT
+----------+--------------------------+-------+---------+
  1/1/2014 | Domain name              |  2233 | $10.98
  1/1/2014 | January Hosting          |  2233 | $54.95
  1/4/2014 | February Hosting         |  2233 | $51.00
  1/4/2014 | February Extra Bandwidth |  2233 | $30.00
+----------+--------------------------+-------+---------+
                                        TOTAL | $146 93
                                      +-------+---------+

```


#### Example 3 - CSV
```go
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
```go
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   ╪
*------------*-----------*---------*
╪ John       ╪ Barry     ╪ 123456  ╪
*------------*-----------*---------*
╪ Kathy      ╪ Smith     ╪ 687987  ╪
*------------*-----------*---------*
╪ Bob        ╪ McCornick ╪ 3979870 ╪
*------------*-----------*---------*
```

##### Example 5 - Markdown Format
```go
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 |
| 1/1/2014 | January Hosting          | 2233 | $54.95 |
| 1/4/2014 | February Hosting         | 2233 | $51.00 |
| 1/4/2014 | February Extra Bandwidth | 2233 | $30.00 |
```

#### Example 6  - Identical cells merging
```go
data := [][]string{
  []string{"1/1/2014", "Domain name", "1234", "$10.98"},
  []string{"1/1/2014", "January Hosting", "2345", "$54.95"},
  []string{"1/4/2014", "February Hosting", "3456", "$51.00"},
  []string{"1/4/2014", "February Extra Bandwidth", "4567", "$30.00"},
}

table := tablewriter.NewWriter(os.Stdout)
table.SetHeader([]string{"Date", "Description", "CV2", "Amount"})
table.SetFooter([]string{"", "", "Total", "$146.93"})
table.SetAutoMergeCells(true)
table.SetRowLine(true)
table.AppendBulk(data)
table.Render()
```

##### Output 6
```
+----------+--------------------------+-------+---------+
|   DATE   |       DESCRIPTION        |  CV2  | AMOUNT  |
+----------+--------------------------+-------+---------+
| 1/1/2014 | Domain name              |  1234 | $10.98  |
