We’ve just added an Excel-like element! That will let you display list of things in a spreadsheet. Look for the plugin “Excel-like HandsonTable”.
It works very much like a repeating group. You pick a data type, then define the data source. The difference is that you need to select which columns you want to show/hide. And you’re all set.
At this stage, the table will only show “simple” fields (whose type isn’t another custom type), and the table is read-only. You can refer to the thing in the current row as the “Table’s current row’s thing”. You can then display it in a group, modify it, etc.
Edition (with automatic saving) will come later!
