There are the following key features:

* **Declarative style.** _Have to write more code, and hell with it._

* **Styling.** _With 7 predefined styles: MySql-like (default), compact, compact lite, compact classic, markdown, 

  rounded and unicode. And you can change it._

* **Header and footer.** _Separated from table body._

* **Multiline cells support.** _See [_example/main.go/_example/04-multiline/main.go](https://github.com/alexeyco/simpletable/blob/master/_example/04-multiline/main.go) for example._

* **Cell content alignment.** _Left, right or center._

* **Row spanning.** _By analogy with the way it is done in HTML. See `Cell.Span` attribute 

  description._

* **Fast!** _Really fast, see [_example/main.go/_example/03-benchmarks-with-others](https://github.com/alexeyco/simpletable/blob/master/_example/03-benchmarks-with-others)._



## Installation

```

$ go get -u github.com/alexeyco/simpletable

```

To run unit tests:

```

$ cd $GOPATH/src/github.com/alexeyco/simpletable

$ go test -cover

```

To run benchmarks:

```

$ cd $GOPATH/src/github.com/alexeyco/simpletable

$ go test -bench=.

```

Comparison with similar libraries see [_example/main.go/_example/03-benchmarks-with-others](https://github.com/alexeyco/simpletable/blob/master/_example/03-benchmarks-with-others)



## Basic example

```go

package main



import (

	"fmt"



	"github.com/alexeyco/simpletable"

)



var (

	data = [][]interface{}{

		{1, "Newton G. Goetz", 532.7},

		{2, "Rebecca R. Edney", 1423.25},

		{3, "John R. Jackson", 7526.12},

		{4, "Ron J. Gomes", 123.84},

		{5, "Penny R. Lewis", 3221.11},

	}

)



func main() {

	table := simpletable.New()



	table.Header = &simpletable.Header{

		Cells: []*simpletable.Cell{

			{Align: simpletable.AlignCenter, Text: "#"},

			{Align: simpletable.AlignCenter, Text: "NAME"},

			{Align: simpletable.AlignCenter, Text: "TAX"},

		},

	}



	subtotal := float64(0)

	for _, row := range data {

		r := []*simpletable.Cell{

			{Align: simpletable.AlignRight, Text: fmt.Sprintf("%d", row[0].(int))},

			{Text: row[1].(string)},

			{Align: simpletable.AlignRight, Text: fmt.Sprintf("$ %.2f", row[2].(float64))},

		}



		table.Body.Cells = append(table.Body.Cells, r)

		subtotal += row[2].(float64)

	}



	table.Footer = &simpletable.Footer{

		Cells: []*simpletable.Cell{

			{},

			{Align: simpletable.AlignRight, Text: "Subtotal"},

			{Align: simpletable.AlignRight, Text: fmt.Sprintf("$ %.2f", subtotal)},

		},

	}



	table.SetStyle(simpletable.StyleCompactLite)

	fmt.Println(table.String())

}

```



Result:

```

 #         NAME            TAX

--- ------------------ ------------

 1   Newton G. Goetz      $ 532.70

 2   Rebecca R. Edney    $ 1423.25

 3   John R. Jackson     $ 7526.12

 4   Ron J. Gomes         $ 123.84

 5   Penny R. Lewis      $ 3221.11

--- ------------------ ------------

             Subtotal   $ 12827.02

```



You can see also [_example/main.go/01-styles-demo/main.go](https://github.com/alexeyco/simpletable/blob/master/_example/01-styles-demo/main.go) for styles demonstration.

```

$ cd $GOPATH/src/github.com/alexeyco/simpletable/_example/01-styles-demo

$ go run main.go

```



More examples:

For more examples see [_example](https://github.com/alexeyco/simpletable/tree/master/_example) directory:

```

$ cd $GOPATH/src/github.com/alexeyco/simpletable/_example

$ ls -F | grep /



01-styles-demo/

02-ugly-span/

03-benchmarks-with-others/

04-multiline/

```



## Styling

There is 6 styles available. To view them, run [_example/main.go/01-styles-demo/main.go](https://github.com/alexeyco/simpletable/blob/master/_example/01-styles-demo/main.go):

```

$ cd $GOPATH/src/github.com/alexeyco/simpletable/_example/01-styles-demo

$ go run main.go

```



## Cell content alignment

You can set cell content alignment:

```go

c := &simpletable.Cell{

	// or simpletable.AlignLeft (default), or simpletable.AlignCenter

	Align:   simpletable.AlignRight, 

	Content: "Subtotal",

}

```



## Column spanning

By analogy with HTML:

```go

c := &simpletable.Cell{

	Span:    2, // Default: 1

	Content: "Subtotal",

}

```

Note: by default `Span` is `1`. If you try to set it to `0`, the value will still be `1`.
