It is not possible to color data grid lines based on an attribute. Therefore I would like an extra (first) column marking rows that need attention. Sorting is not an option in this case. The data grid is filled by a microflow, creating a list by retrieving an entity. Is it possible to add a new column to this list and fill it with a value based on the content of one or two attributes of the entity?
Add an attribute to the grid object. In the source microflow you can iterate over the list. In this loop you can check which rows need to have the "highlight" attribute changed.
When you choose enumeration for the "highlight" attribute and link images to the different enumerations you could show an exclamation mark image at the start of each important row.
