Customdata should accept a data frame

My understanding is that anything that can be serialized to JSON from R can be passed to customdata, so probably what I want to do is fine for that part I'm not sure where I read this, I can't set customdata to a data frame.

My request is to make it possible to specify in the special "%{}" notation of hovertemplate to access fields of customdata. Or is there a more appropriate way to do this?

I would like something this to work:
plot_ly(x=mpg$displ, y=mpg$hwy, customdata=mpg, hovertemplate="x: %{x}\ny: %{y}\ncustom: %{customdata$year}")
alternatively customdata["year"] with javascript syntax, or whatever is appropriate.

该 issue 没有指明文件、测试或入口点。首先跟踪 customdata 和 hovertemplate 的处理方式，并使用提供的 mpg 示例重现这一限制。当可以将数据框作为 customdata 传入，并且 hovertemplate 能够使用文档所述的语法访问其 year 字段时，即表示完成。
