Wall Table Grouping?

[ACADuser]

I wanted a simple wall table with an added field to show 2x the wall length for drywall length.

But when I added this %(length / 12 * 2).round(2)%  to one of the fields in each wall "object Information" the table displays all walls as line items.

Is there a way to do this and keep the simple table?

Try checking the "sum similar rows" option to see if that gives you what you need.
