The {{cell}} template can be used to create a table cell with a specified background color.

{{cell|COLOR}}

The template takes one unnamed parameter as input, which is the background color of the table cell. The default content of each cell is a single non-breaking space with a font-size of 50%. To override the content of each cell, use a second unnamed parameter. To override the default font-size, use the style= parameter.
