Hi @AM-BE - as an update, in case this fits your use case, customizing background color of cells in Table is now possible in both Retool Cloud, and the latest Retool self-hosted release (version 3.6) in the column-level Appearance > Background setting. Check out @AnsonHwang's comment here describing how to do this using item
I've separately linked this post to a feature request internally to conditionally set _text_ color (not only background color) but I don't currently know of plans to support this. Hopefully background color settings will help get you close to what you're looking for in the meantime!
