A feature in QGIS I rarely use, but if I need it, I’m glad it exists, is conditional formatting in QGIS attribute tables. The similar feature in Excel I use all the time, but QGIS has so many other possibilities to get things done, I use it less often.
So for those of you who haven’t used the feature, what is it? In short you can format cells or rows in the attribute tables based on the content of the cells. In the examples below I used it make empty cells to stand out in a attribute table that contains more than 2000 features. In the next part of this post I’ll go over the details of conditional formatting.
