AutoCAD Civil 3D

[#1]

I have set up a table style to display the type of structure, top of casting, and invert in and out elevations. I have also added a column to display the depth (rim to sump height). When the structure is a headwall, no depth is needed; however, the table displays this data as "???". Is there a way to only show depths greater than zero within the table editor for rim to sump height?

you might be able to build an expression that shrinks the text really small when a certain condition exists therefore making it look as if it's not there.

Also if only 1 or 2 structures have the question marks why not just use a wipeout to cover them.

Unfortunately, you can't use an expression for the height of the text within a table. It works just fine within a label style, just won't work for a table. You can use the expression within the table however. I was hoping an expression like IF({Rim to Sump Height},{Rim to Sump Height},-1) and simply tell the text component to hide negative values but that doesn't seem to work. It seems that if there is no {Rim to Sump Height} it simply returns ??? if that value is ever querried.
