Hello @wvdploeg,
Thank you so much for your suggestion. Ability to change background color for single cells is developed and will be released with the pro version of the plugin. But we don’t have an option to change text colors for single cells. We will add it to our development tasks list to discuss. In the meantime, if you are familiar with the CSS, every table container on front-end gets a unique class name that goes as wptb-table-{table-id}. You can target a specific table that you want to add the text color and override it’s children’s element styles.
Best regards.
