#### 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 ╪
*------------*-----------*---------*
╪ John ╪ Barry ╪ 123456 ╪
*------------*-----------*---------*

#### 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{"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.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())
}
```
#### TODO
- ~~Import Directly from CSV~~ - `done`
- ~~Support for `SetFooter`~~ - `done`
- ~~Support for `SetBorder`~~ - `done`
- ~~Support table with uneven rows~~ - `done`
- ~~Support custom alignment~~
- General Improvement & Optimisation
- `NewHTML` Parse table from HTML
