#### 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())
}
```
