There is a trick to creating highlight tables in Tableau. The first is to create a text table. See the Creating a text table recipe in this chapter for the steps. Once you have the text table, you can drop a measure onto Colors in the Marks card. This colors your text table with a gradient of colors, which honestly will make your text table very hard to read.
