How can I define a legende with gradient background colors

Question

How can I use the gradient background colors in legend?
As soon a gradient color is used the color is handled as text

Thank Helmut

@startuml
skinparam backgroundcolor #AntiqueWhite-Gold
skinparam classBackgroundColor #CornflowerBlue|Wheat

package example #GreenYellow/LightGoldenRodYellow {
  class Dummy
note left of Dummy #blue\9932CC
  this is my
  note on this class
end note
}

legend
|<#CornflowerBlue><color:#darkblue> single color class (only first background color can be used darkblue is text color) |  |

|<#AntiqueWhite-Gold><color:#darkblue> background |  |
|<#Wheat|CornflowerBlue><color:#darkblue> multi color class |  |
|<#blue\9932CC><color:#darkblue> note |  |
|<#GreenYellow/LightGoldenRodYellow><color:#blue> package |  |
endlegend

Your question seems to be about tables not supporting gradients rather than legends - I mean if you put the same table into a rectangle, then you get the same non-support for it:

You've probably discounted it already because it doesn't fill the whole cells, but don't forget that you can use the <back> feature with [some] gradients.  It won't colour a whole cell, and it doesn't support all the gradient types, but it might work for some of your use cases:

I think you've asked the wrong question, but I'll answer it as posed ("How can I define a legend with gradient background colors?").
You can use a STYLE to define a gradient background for your legend:

But I think your question is really about adding gradient fill to table cells, and my only suggestion for that is to use <back> (see comment above), but the fact it doesn't fill the whole cell probably makes it not suitable for you.  Although by using monospace and right padding with spaces, you can get close:
