#### 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, "testdata/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, "testdata/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   ╪

table.SetBorders(tablewriter.Border{Left: true, Top: false, Right: true, Bottom: false})
table.SetCenterSeparator("|")
table.AppendBulk(data) // Add Bulk Data
table.Render()
```

##### Output 5
```

#### Example - 7 Table Cells with Color

Individual Cell Colors from `func Rich` take precedence over Column Colors

```go
data := [][]string{
	[]string{"Test1Merge", "HelloCol2 - 1", "HelloCol3 - 1", "HelloCol4 - 1"},
	[]string{"Test1Merge", "HelloCol2 - 2", "HelloCol3 - 2", "HelloCol4 - 2"},
	[]string{"Test1Merge", "HelloCol2 - 3", "HelloCol3 - 3", "HelloCol4 - 3"},
	[]string{"Test2Merge", "HelloCol2 - 4", "HelloCol3 - 4", "HelloCol4 - 4"},
	[]string{"Test2Merge", "HelloCol2 - 5", "HelloCol3 - 5", "HelloCol4 - 5"},
	[]string{"Test2Merge", "HelloCol2 - 6", "HelloCol3 - 6", "HelloCol4 - 6"},
	[]string{"Test2Merge", "HelloCol2 - 7", "HelloCol3 - 7", "HelloCol4 - 7"},
	[]string{"Test3Merge", "HelloCol2 - 8", "HelloCol3 - 8", "HelloCol4 - 8"},
	[]string{"Test3Merge", "HelloCol2 - 9", "HelloCol3 - 9", "HelloCol4 - 9"},
	[]string{"Test3Merge", "HelloCol2 - 10", "HelloCol3 -10", "HelloCol4 - 10"},
}

table := tablewriter.NewWriter(os.Stdout)
table.SetHeader([]string{"Col1", "Col2", "Col3", "Col4"})
table.SetFooter([]string{"", "", "Footer3", "Footer4"})
table.SetBorder(false)

table.SetHeaderColor(tablewriter.Colors{tablewriter.Bold, tablewriter.BgGreenColor},
	tablewriter.Colors{tablewriter.FgHiRedColor, tablewriter.Bold, tablewriter.BgBlackColor},
	tablewriter.Colors{tablewriter.BgRedColor, tablewriter.FgWhiteColor},
	tablewriter.Colors{tablewriter.BgCyanColor, tablewriter.FgWhiteColor})

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})

colorData1 := []string{"TestCOLOR1Merge", "HelloCol2 - COLOR1", "HelloCol3 - COLOR1", "HelloCol4 - COLOR1"}
colorData2 := []string{"TestCOLOR2Merge", "HelloCol2 - COLOR2", "HelloCol3 - COLOR2", "HelloCol4 - COLOR2"}

for i, row := range data {
	if i == 4 {
		table.Rich(colorData1, []tablewriter.Colors{tablewriter.Colors{}, tablewriter.Colors{tablewriter.Normal, tablewriter.FgCyanColor}, tablewriter.Colors{tablewriter.Bold, tablewriter.FgWhiteColor}, tablewriter.Colors{}})
		table.Rich(colorData2, []tablewriter.Colors{tablewriter.Colors{tablewriter.Normal, tablewriter.FgMagentaColor}, tablewriter.Colors{}, tablewriter.Colors{tablewriter.Bold, tablewriter.BgRedColor}, tablewriter.Colors{tablewriter.FgHiGreenColor, tablewriter.Italic, tablewriter.BgHiCyanColor}})
	}
	table.Append(row)
}

table.SetAutoMergeCells(true)
table.Render()

```

#### Example 8 - Set table caption
```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"})
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 7
```
+------+-----------------------+--------+
| NAME |         SIGN          | RATING |
+------+-----------------------+--------+
|  A   |       The Good        |    500 |
|  B   | The Very very Bad Man |    288 |
|  C   |       The Ugly        |    120 |
|  D   |      The Gopher       |    800 |
+------+-----------------------+--------+
Movie ratings.
```

#### Example 8 - Set NoWhiteSpace and TablePadding option
```go
data := [][]string{
    {"node1.example.com", "Ready", "compute", "1.11"},
    {"node2.example.com", "Ready", "compute", "1.11"},
    {"node3.example.com", "Ready", "compute", "1.11"},
    {"node4.example.com", "NotReady", "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 8
```
NAME             	STATUS  	ROLE   	VERSION 
node1.example.com	Ready   	compute	1.11   	
node2.example.com	Ready   	compute	1.11   	
node3.example.com	Ready   	compute	1.11   	
node4.example.com	NotReady	compute	1.11   	
```

#### 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:

```go
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())
}
```
