Essentially, with custom content, you need to drop widgets inside the cell.
For example, imagine that I want to add custom content to a new column for the attribute Name. First, on the Edit Column Item, you select that attribute:
Then you can drag any widget that you want and use and drop it inside the cell. As an example, the below image shows how this can be achieved for a Badge (with the badge caption set to the Name attribute).
Please note that if you don't need a specific widget, but just show the attributes you mentioned, you don't need custom content, but attribute instead (see image below).
