如何将数据传递到 Go 的 `text/template` 包中的嵌套模板？

package main

import (
    "text/template"
)

func main() {
    // Define the custom function to combine arguments
    func args(vs ...interface{}) []interface{} { return vs }

    // Parse the template with the custom function registered
    t, err := template.New("t").Funcs(template.FuncMap{"args": args}).Parse(...)
    if err != nil {
        // Handle error
    }

    // Render the template with the custom function
    t.ExecuteTemplate(..., template.Args(..., 5))

    // Access the arguments in the nested template
    {{ define "image_row" }}

       To stuff here {{index . 0}} {{index . 1}}

    {{ end }}
}
