Golang模板中的可变参数

Question

Is there any way to "spread" parameters in Go templates?

In my code I have a function that returns the properties of a list of structs as a string slice

"colStr": func(col string, a ...interface{}) []string {
    s := make([]string, len(a))
    for i, v := range a {
        if structs.IsStruct(v) {
            s[i] = db.Str(structs.Map(v)[col])
        }
    }
    return s
},

But how do I pass to this function? In the template itself, I have something that looks like this

{{list (colStr `Number` .QuoteProofs...) `&`}}{{end}}

But that gives me

template: HTML:17: unexpected <.> in operand

Is there any way to do this with templates?
