Golang：在Go模板中按切片排序地图

I have a question about how to order a map by a slice in Go Templates and if it is possible.

Problem: I have a slice of ordered variable names that I want to display on a website, accompanying them I have a map of metadata of variable information that I would like to display together with the variable.

If I have the following struct that I pass in to the template:

type Data struct {
       Variables    []string
       Information  map[string]int
}

I would iterate over the slice and pass the variable name in to the map

{{ range $v := .Variables }} {{ index .Information $v }} {{ end }} // Doesn't work.

Here's a Go Playground with the example. https://play.golang.org/p/AL2csnXdoU

Question: How can I do this?

I am fairly new to Golang. Thankful for any input.

The following should work. To access .Information inside range, you should use $, which is basically d in your Playground example.

{{ range .Variables }} {{ index $.Information . }} {{ end }}
