I use the Data Grid control quite heavily. During text editing it would be very useful with syntax highlighting of column separtor commas and other keywords/operators, e.g. bold, links, color and size - for quicker and easier editing. When having large Data Grids, one quickly looses track.
As a workaround, I constantly copy and paste between Balsamiq Data Grids and text editing in Visual Studio Code, making for quite a tedious workflow.
