ASCII Table Writer
=========
[![Build Status](https://travis-ci.org/olekukonko/tablewriter.png?branch=master)](https://travis-ci.org/olekukonko/tablewriter) [![Total views](https://sourcegraph.com/api/repos/github.com/olekukonko/tablewriter/counters/views.png)](https://sourcegraph.com/github.com/olekukonko/tablewriter)
Generate ASCII table on the fly ... Installation is simple as
go get github.com/olekukonko/tablewriter
#### Features
- Automatic Padding
- Support Multiple Lines
- Supports Alignment
- Support Custom Separators
- Automatic Alignment of numbers & percentage
- Write directly to http , file etc via `io.Writer`
- Read directly from CSV file
- Optional row line via `SetRowLine`
- Normalise table header
- Make CSV Headers optional
- Enable or disable table border
- Set custom footer support
#### 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
```

- ~~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
