How can I draw a sample line with a style within a table cell?

Question

I'd like to have a legend (or a note) with a table, describing all the styled lines in a diagram.

so, I'd want something like:

@startuml

!$style1 = "#red,dashed"

!$style2 = "#blue,dotted"

...

legend

| Line Style | Description |

| -[$style1]-> | Scenario 1 |

| -[$style2]-> | Scenario 2 |

endlegend

@enduml

the Line Style column should have to display visually the lines with their styles applied.

So, I'd like to see it something like this (this snippet is just a visualization, demoing what I'd like to achieve within the cells):

Note, that I do have to use the $style1 and $style2 within the legend (cannot put just <color:#red>--></color>, etc., for example) since the styles come from an external configuration.

Is there a way to achieve this?
