Using the variables extension, I want to change the background color of a cell in a table. So far I've done this:

{{#vardefine:green|<span style="background:Green; color:White">text</span>}}

The problem is that, when I add {{#var:green}} to the cell, only the text itself has a green background. Ideally, I want the whole cell to have a background color, like it does if I use this:

| bgcolor="#ff00ff" | test

or this

| style="background:silver" |silver

in the cell.

Does anyone know how to solve this?
