|
}
|
||
|
|
|
||
|
|
table := tablewriter.NewWriter(os.Stdout)
|
||
|
|
table.SetHeader([]string{"Name", "Sign", "Rating"})
|
||
|
|
|
||
|
|
for _, v := range data {
|
||
|
|
table.Append(v)
|
||
|

#### 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())
|
||
|
|
}
|
||
|
|
```
|
