I’d avise using Skuid’s conditional rendering to achieve this. Unfortunately conditional rendering is not implemented in Table Columns. So this function would be possible in an individual record (using a field editor where the Sold Funding Type was hidden until the State was Closed Won).
One workaround is to put this in a Table Drawer. You can implement a field editor in the drawer and hide the field as described above. Unfortunately this does not enable mass update.
So good news, bad news. Hopefully you can work it out.
