The user can, also, specify some styling information for each column, such as background color.

Applications without support for the APNG extension show only the ...

Editors are encouraged to make use of tools, such as Color Brewer 2 to create Brewer palettes, listed at MOS:COLOR for color scheme selection used in graphical charts, maps, tables, and webpages with accessibility in mind for color-blind and visually impaired users.
