Download Table from Data Expression

[WilliamRockwell1]

I can get the source data download from a layer, but not a data expression (same hosted layer in ArcGIS online). Why is this not allowed? It would really help me as the data expression cleans up several fields nicely, but I can't have users download the data without this. Frustrating.

@WilliamRockwell1, did you happen to find a workaround to this?

Right now, I have Table A related to Table B. Table B is related to Table C. Using a data expression, I can create a table that has each feature from Table C, along with info from Table B and Table A (essentially creating a flat file), but like you, I can't download it, and even trying to copy and paste the values into a blank Excel sheet doesn't work well at all (all the values are in a single column with no field headings).
