Hi there,
That is what I'm trying to achieve. However after a long fiddling around, I've managed to achieved a somewhat similar table.
What I did is I made 4 seperate tables (by playing around with zone property and purpose to seperate Ground Floor and Mezz), then I created those 4 seperate tables each with their respective field (ground floor area, mezz area, gross area etc), then I stitch them together on the layout page.
Theoretically it works however I'm still trying to find out if there is a smarter way to achieve this table in a single schedule without creating a bunch of schedules and stick them together. I've added snippets of my schedules with it's scheme settings in hope the experts here can shed some light on this!
