This workflow snippet shows a possible way to append colors to individual cells depending on the value. We configure the Rule Engine node to determine the colors of the cells depending on the certain condition. The colors could be defined as a string or as a hexadecimal code (see Links for an example). Then we use the string manipulation node to append the colors to individual cells. To explore the result table interactively, right-click on the node "Table View" and select "Interactive View: Table View" in the dropdown.
